INTRODUCTION.

By JOSEPH A. HOLMES.

The tests of washing and coking coals and of the behavior of the 

resulting coke in cupola practice, as reported herein, were made 

during the fiscal years 1905 and 1906 at the St. Louis fuel-testing 

laboratory of the United States Geological Survey. These tests 

were carried on in connection with similar investigations of the 

steaming and gas-producing qualities of the same coals and of the 

possibility of improving such coals by briquetting. This work was a 

part of the general inquiry concerning the most economical manner 

.of utilizing each type of coal tested.

Many coals as received from the mine were found to be too high in 

ash, in sulphur, or in phosphorus to make satisfactory metallurgical 

coke without prior treatment, and some coals possessed better coking 

qualities than others. It was found that the washing of some coals 

so reduced the percentage of ash and sulphur as .to make available 

for the production of coke a- coal which otherwise would have had no 

value for this purpose. In the following pages are reported the 

details of the washing of coal, the production of coke therefrom, and 

the behavior of the coke in the cupola when utilized for the 

production of castings, the results of each test being tabulated in 

full. A study of these tables indicates many important facts as to 

the behavior and treatment of the coals mined in the various portions 

of the 'United States when prepared as metallurgical coke.

The washing tests of 1905 were not as satisfactory as the later tests 

because of inadequate storage facilities and the lack of certain equipment, but the latter was added in time for the tests of 1906. An

important result of the washing tests is shown in the percentage of 

ash and sulphur actually removed. The reduction of these impurities by washing, of course, increases the percentages of fixed carbon, 

and volatile matter over the amounts present in raw coal. These 

facts, the number of washings, and the methods of washing, are 

recorded, thus furnishing valuable data as a guide to the treatment necessary to render each coal tested most suitable for coking. 

Altogether there were 101 regular washing tests and 12 special tests.

The results of these tests show an increase in moisture of 10 to 30 

per cent, a reduction in ash in the 1905 tests of 15 to 50 per cent and 

in the 1906 tests of 20 to 60 per cent, and a reduction in sulphur in 

the 1905 tests of 10 to 40 per cent and in the 1906 tests of 10 to 50 

per cent. A few examples of the total amount of reduction may be 

mentioned. A raw coal containing 5.05 per cent of sulphur contained after washing 2.47 per cent, a total removal of 55 per cent. 

Proportionate reductions in sulphur were made in coals containing 

lesser amounts. The ash in a raw coal containing 42.56 per cent 

was reduced by washing to 29.67 per cent, a total removal of 65 per 

cent. In a similar manner ash in a raw coal containing 15.72 per 

cent was reduced to 10.16 per cent, a total removal of 41 per cent; 

and in a coal containing 9.81 per cent to 5.38 per cent, a total removal 

of 59 per cent. It is evident that coals which are in the raw state 

utterly unfit for steaming purposes can be made fairly good steaming 

coals by washing, and that coals unsuited for coking can be made 

available in the same way.

It is proposed to conduct during the next fiscal year washing tests 

with much improved apparatus at the fuel-testing plant recently 

established at Denver, Colo., where experiments in washing and coking 

will be made on the coals mined in the Rocky Mountain region, with 

a view to determining what can be done to make them available for 

the production of metallurgical coke.

The coking tests were made in ovens of the regular beehive pattern, 

two of standard size 7 feet high, and one of standard diameter 6 feet 

4 inches high. Samples of coke were taken from five different parts 

of the oven in practically the same location for each test, so as to give 

a standard method of comparison for each coke. The present report 

covers 192 tests, made on 100 coals, the samples having been collected from 17 States and 1 Territory. One hundred of these tests 

were made on raw coal, 82 on washed coal, and 10 under miscellaneous conditions. In some of these tests it was found that the addition 

of pitch produced coke from coal which wben tested raw gave either 

no coke or coke of an inferior quality. In other tests the addition of 

pitch did not improve the quality of the coke. The tabulated results 

of the coking tests should be studied in the light of the description of 

the resulting coke which accompanies the tables. The physical tests
INTRODUCTION. 7

to determine the compressive strength of the coke or, in other 

words, the height of the furnace burden which the coke will support showed only the worthlessness of such determinations. The 

compressive strength of a given coke made with the same coal ranged 

from about 700 pounds ultimate strength per square inch to over 

2,000 pounds. As a coke with compressive strength of 48 pounds 

will support the burden of any modern furnace, it is evident that 

this test is of little or no practical value, especially as the burden 

borne by the coke may be greatly modified by the action of heat, by 

attrition, and by other factors. The inquiries seem to indicate that 

the yield of coke is increased and the proportion of breeze reduced 

by preliminary crushing. Further experiments are necessary to 

verify these determinations, as well as to indicate the limit of fineness of such crushing. Fine crushing appears to increase the strength 

of the coke, which is apparently influenced also by the amount and 

distribution of ash.

More complete coking tests will be carried on with a view to procuring more conclusive data along the lines above indicated, also 

with a view to determining more accurately the loss of sulphur from 

coal to coke, which varies with the coals and the method of treatment. These coking tests are being continued at the new plant at 

Denver on beehive ovens with two heights of crown, in order to determine the treatment necessary to produce good metallurgical coke 

from the coals mined in the Rocky Mountain region.

The great need of the immediate future in connection with coking 

experiments is the conduct of such tests in by-product ovens, and it 

is hoped that funds may soon be had which will permit the erection 

and operation of such ovens.

The cupola tests of coke in 1905 and 1906 were carried on along 

lines fully described in Professional Paper No. 48. The. results as 

set forth in the following tables give the details of 170 cupola tests. 

The data concerning record of melt, taken in connection with the 

indications of the source of the coals and the analyses of the corresponding coke, furnish interesting facts as to the melting ratio of 

iron to coke, the rate of melting per' hour, and the amount of iron 

recovered. Equally interesting is the table giving the chemical 

effect on iron from cupola tests of cokes made from coals mined in 

various States. It is not contemplated that these cupola tests will 

be continued during the fiscal year, in view of the necessity of devoting the available funds to the study of the coking qualities of western 

coals.

REPORT FOR 1905. 

IMPROVEMENT IN EQUIPMENT.

The lack of adequate storage facilities and the constant demand 

on the weighing and conveying apparatus for delivering coal to the 

other sections of the fuel-testing plant, which greatly interfered with 

the washing tests made during 1904,a were again felt in 1905 and 

tended somewhat to vitiate the results, although much improvement 

was made in the equipment.

In order to eliminate these difficulties, important changes were 

made during the year in the arrangement of the washer equipment. 

The storage capacity available during 1904 was increased'from 175 

tons to 350 tons. Additional "shed bins" of 150 tons aggregate 

capacity were provided outside the washer plant for storing coal at 

.times when the regular washer bins were filled.

The coal was shoveled from the cars direct to the crusher or to a 

topper scale. By means of a combination elevator conveyor the 

coal could 1)6 ttansleired fr-om the hopper scale or crusher to any one of 

the twelve regular storage bins, or from-one bin to another; or could 

be transferred to belt conveyors for delivering the coal to the boiler 

section and. pther divisions of the plant. The elevator conveyor 

referred to was relieved of a large portion of the work of handling 

coals for the gas-producer and boiler sections by a 30-inch Jeffrey belt 

conveyor, wjiich was installed to run from the car siding to the bins of 

these sections for the purpose of delivering coal to them direct from 

the cars.

All washing tests made during 1905 were made on the Stewart jig 

used during 1904, at a speed of 35 revolutions per minute and 6-inch 

stroke. The sludge-recovery system, with the customary perforatedbucket elevators, was used in reclaiming the washed coal and refuse

No. 48, 1906, p. 1460.

after washing. Owing, however, to the fact that there were only two 

sludge tanks one for the washed coal and one for the refuse only 

one jig could be operated at a time, since if two or more jigs were 

operated their output would become mixed in the sludge tanks.

With the existing arrangement of the washery it was necessary to 

use the same water over and over again. The washed-coal sludge 

tank, supplied with water from the city mains, was used as a reservoir from which the water was delivered, principally beneath the 

screens of the jigs. A considerable amount of fine coal was thus carried over from the sludge tank. The bulk of this fine coal settled to 

the bottom of the jig body, where it became mixed with the refuse 

and was carried on to the refuse sludge tank.

All coals tested were passed through an 18 by 24 inch Cornish 

tooth-roll crusher, which breaks the coal down to a maximum size 

of about 2 inches, although, of course, a considerable proportion may 

be much smaller, depending on the nature of the coal.

The. power for operating the plant was furnished by a 12 by 16 inch 

Frost steam engine, belted to a main shaft from which the jigs and 

other machinery of the plant were driven. The steam for this engine 

was received from the boiler section.

PERSONNEL.

The 1905 tests were made under the direction of John D. Wick.

REPORT FROM JANUARY i, 1906, TO JUNE 30, 1907. 

EQUIPMENT AND OPERATION.

On February 22, 1906, the washery plant was almost entirely 

destroyed by fire, and with it a few samples of coal that were on hand 

in the storage bins. The plant was immediately rebuilt, the former 

arrangement being followed throughout.

From January 1 to December 15, 1906, one Stewart jig was used 

in making all the washing tests. During December, 1906, a special jig 

was installed. This jig was of the center-plunger type, i. e., the 

plunger was directly beneath the screen, and the upstroke of the 

plunger caused the pulsation. The plunger had no valves, but valves 

Avere arranged in the sides of the jig body to admit the supply water 

on the downstroke of the plunger. Cams and springs were used in 

such a manner that the plunger had a slow downward and a quick 

upward stroke. The screen of this jig was. 4 feet wide by 5 feet long 

and was made of strips of No. 10 wire running lengthwise of the screen 

frame and set one-sixteenth inch apart. The length of the stroke 

was adjustable up to 4 inches. The depth of the coal bed was also 

adjustable.
10 WASHING, COKING, AND CUPOLA TESTS.

Owing to the fact that the power for operating the washer plant 

was furnished by a 12 by 16 inch Frost steam, engine, belted to a main 

shaft from which the jigs and other machinery were driven, it was 

impossible to change the speed of the jigs. Better results could have 

been obtained on some coals tested had it been possible to change the 

speed to suit the length of stroke used.

As the only crusher available for this work was an 18 by 24 inch 

Cornish tooth-roll crusher, it was impossible to crush some coals down 

as fine as they should have been crushed. However, an adjustablemesh bumping screen was installed in January, 1907, in such a manner that the coal was first passed over this screen, and the tailings 

then passed on to the crusher, while the fuel which went through the 

.screen dropped into the bin over the jig. The product of the crusher 

was then elevated again to the screen, and this cycle of operation was 

repeated until all the coal passed through the screen.

In December, 1906, a float and sink testing equipment was installed. 

Before each washing test was made, samples of the raw coal, quartered down to 2 kilograms each, were tested on four 'different specificgravity solutions. In this manner it was possible to make a preliminary determination of the result of a separation under varying percentages of washed coal and refuse. The coal was then washed with 

the jig regulated to discharge as refuse a percentage about equal to 

the percentage found advisable from the float and sink tests. After 

a washing test was made, a sample of the refuse was taken and quartered down to four samples of 2 kilograms each, and these were also 

tested on the specific-gravity solutions. The test showing the highest percentage of float coal and having an analysis which agreed 

fairly with that of the washed coal was then used in determining the 

percentage of "loss of good coal in the refuse." In this manner the 

efficiency of the test was shown.

PERSONNEL.

John D. Wick, assisted by Edward Moore, was in charge of the 

washing tests from January 1 to June 30, 1906; J. H. Gould from 

July 16 to October 12, 1906; and G. R. Delamater from November 

15, 1906, to June 30, 1907.

EXPLANATION OF TABLES.

"Percentage of reduction" and "amount actually removed." The 

"percentage of reduction" is the comparison made of the percentages 

of the impurities in the raw coal and in the washed coal. It will be 

readily understood that if the ash alone is reduced by washing, the 

fixed carbon and volatile matter will form a higher percentage of the 

washed coal than of the raw coal. In actual practice, however, it is
WASHING TESTS. 11

impossible to make so perfect a separation that the washing process 

will not remove portions of some constituents other than the impurities, and therefore the percentage of each constituent in the washed 

coal is affected by the reduction of each of the other constituents. 

This is clearly indicated in test 192, on Alabama No. 6, and test 198, 

on Virginia No. 6. A comparison of the raw-coal and washed-coal 

analyses in these two tests shows that in the test on Alabama No. 6 

the percentage of sulphur was the same in the washed coal as in the 

raw coal; and in the test on Virginia No. 6 the sulphur in the washed 

coal was higher than in the raw coal. It will therefore be seen that a 

simple comparison of the raw-coal and washed-coal analyses will not 

always show whether any of the sulphur in the raw coal was actually 

removed with the refuse in washing.

Formulas. In order that these percentages might be determined, 

the following formulas were compiled and used in making up this 

report. It will be noted by referring to the test data (p. 15) that 10 

per cent of the original sulphur in the raw coal was actually removed 

with the refuse in washing Alabama No. 6, and that 13 per cent was 

actually removed in washing Virginia No. 6: 

Let X = the percentage of reduction of any constituent.

Y = the percentage of any constituent removed by washing.

M = the percentage that the amount of the constituent in the 

washed coal is of the raw coal..

a = the percentage that the washed coal is of the raw coal. 

& = the percentage of the constituent in the washed coal. 

c = the percentage of the constituent in the raw coal.

Then X = , M = a&, and Y = ^ ^.

COKING TESTS.

By A. W. BELDEN.

EQUIPMENT.

The ovens in which the tests of the coking qualities of coals have 

been made are of the regular beehive pattern. Of the battery of three 

ovens two are of standard size, 12 feet in diameter and 7 feet high, 

the third is 12 feet in diameter and 6 feet 4 inches high. This change 

was made by raising the bottom of one of the standard ovens 8 inches 

with well-tamped loam and bottom tile of the usual size. The object 

of the change was to bring the charge nearer the dome of the oven 

and effect a more rapid penetration of heat.

For the first nineteen tests the small oven only was used. In the 

twentieth charge one of the 7-foot ovens was blown in, and two ovens 

were used continuously during the remainder of the work one of each 

size. Owing to the small supply of coal it has not been possible to use 

more than two ovens, and they may, therefore, be considered as end 

ovens. Some suppose that end ovens yield results less favorable 

than those from ovens located between other heated ovens, but, 

even if this supposition is correct, the difference is fully balanced by 

the greater care bestowed on these experimental ovens as compared 

with ovens operated under normal conditions. As both of the ovens 

used are, in the sense indicated, end ovens, the results obtained in each 

are comparable one with the other.

In' charging the ovens for the first nineteen tests the larry used held 

less than 1 ton. This necessitated the filling and emptying of the 

larry six to eight times before the charge was completed. Each posr 

tion thus became hot and began invariably to gas, and often to blaze 

before the next portion of the charge was added. This unfortunate 

state of affairs is believed to be responsible, at least in some measure, 

for cross lamination and cross breakage of the coke, layers of coal as 

charged showing plainly in many of these tests in each oven drawn. 

The average time of charging with this device was about one hour. 

After the nineteenth charge a standard-size larry was installed and the 

time of charging was reduced to an average of seven minutes. With 

this change the lamination and cross breakage referred to disappeared,, 

showing that the whole charge should be put in at once.

PERSONNEL.

The writer took charge of this work in May, 1905, succeeding Fred 

W. Stammler, of Johnstown, Pa. He was assisted by W. E. Vickers, 

of Pocahontas, Va., to whom in large measure is due whatever sue-, 

cess has been obtained during these investigations.

PROCEDURE OF TESTS.

All coal was finely crushed through a Williams mill unless otherwise tested for definite comparison of results, and these exceptions 

are noted in the subjoined detailed report (pp. 21-26). The coals 

not crushed were, when unloaded from the cars, put through rolls 

having an aperture of 1| inches. The coals put through the Williams 

mill will vary somewhat, depending on the nature of the coal, but will 

practically all pass through a 10-mesh sieve, as shown by the following 

report by the laboratory on an average sample: Amount remaining 

on 10-mesh, 15.08 per cent; on 20-mesh, 35.71 per cent; on oO-mesh, 

12.89 per cent; on 40-mesh, 8.53 per cent; on 60-mesh, 9.33 per cent; 

on 100-mesh, 9.13 per cent; through 1 OO-mesh, 9.33 per cent.

Both the door and the trunnel head of the oven were always closed 

directly after the oven was drawn and it was allowed to gather heat, 

the length of time varying as necessity demanded. The average time 

was one arid one-half hours.

The sample' of coal was taken at regular intervals as the charge was 

emptied from bin to larry, by means of a small shovel holding about 

one-fourth pound. The total weight of the sample averaged 45 

pounds.

The sample of coke was taken from five different parts of the oven, 

as nearly as possible from the same location for each test, as follows: 

2 feet from the oven door; 2 feet from each side, on a line drawn from 

the center of the oven; at the center; and 2 feet from the back wall, 

on a line with the point of selection of the pieces taken from the door 

and the center. The separate pieces of coke extended the whole 

height of the charge and were as nearly uniform in size as possible. 

-* In beginning the series of tests, before the ovens were fully seasoned, 

the first'charges showed a rather large percentage of breeze, and black 

butts due to cold bottom were produced. It was unfortunate that 

these first tests should have been made on coals that were supposedly 

noncoking, as the condition of the oven did not permit it to give as 

effective service as it would probably have given .under other and 

more favorable conditions.

EXTENT.OF TESTS.

In the scope of this report, covering the period from July 7, 1905, 

to February 20, 1907, are included results from 192 tests of 102 coals 

from seventeen States and one Territory, "as shown in the accoin-
20 WASHING, COKING, AND CUPOLA TESTS.

panying table. Of these tests, 100 were made on raw coal, 82 on 

washed coal, 1 on raw coal with the addition of pitch, 6 on washed 

coal with the addition of pitch, 1 on washed coal with the addition of 

asphalt, and 2 on coals of widely varying composition. Of the 102 

different coals, 8, viz, Arkansas No. 9, Illinois No. 19, Indiana Nos. 3 

and 18, Ohio No. 3, Maryland No. 1, and. Wyoming Nos. 3 and 5, 

produced no coke. Arkansas No. 9 and Maryland No. 1 were coked 

by the addition of pitch to washed coal. Four tests were made on 

Pennsylvania No. 9 (pp. 24, 32, 41); two tests with raw coal gave only a 

few pieces of coke; a third, with washed coal', produced coke of inferior 

quality; and the fourth, with the addition of 5 per cent pitch to raw 

coal, produced coke of no better quality than that from washed coal. 

Of Indiana No. 3, Ohio No. 3, and Wyoming Nos. 3 and 5, there was 

not enough for further tests.

TABULATION OF RESULTS.

The results of the coking tests will be found in the detailed report 

on each sample, presented below. For convenience of comparison 

data are given as to the yield of dry coke from dry coal as well as coke 

as received from coal as charged. The analyses of both coal and coke 

as received and on dry basis are also given. No distinction is made 

between breeze and ash, as it was found impossible to separate them 

with any degree of accuracy, and both are represented in this report 

in the item "breeze." This breeze includes everything that will pass 

through a fork with tines 1| inches apart, after thorough shaking, and 

its percentage is much higher than that from regular operations, but 

is comparable in all tests. It was not deemed necessary or advisable 

to size the coke, and under this caption is included everything over 

the l|-inch tine fork. Except in a few special cases the determination of phosphorus was not made on coke having over 2 per cent of 

sulphur, and when more than one test was made on a coal in the same 

condition this determination was also omitted.

36 WASHING; COKING; AND CUPOLA TESTS. 

DESCRIPTIONS' OF COKE AND REMARKS.

The following notes are given to supplement the information 

contained in the preceding table:

"Cell structure" refers to the general appearance as to size and 

not to the number of cells as given by percentage of cells by volume. 

In many tests the cell structure as determined from general appearance is small when the percentage by volume indicates quite the 

reverse. (See, for example, test 29, Pennsylvania No. 8 coal, p. 24.)

Alabama No. 2 B. Test 142: Soft, dense coke; dull appearance; cell structure.Very 

small; breakage, lumps of irregular size; 1-inch black butts.

Alabama No. 3. Test 138: Dark-gray color, some deposited carbon; cell structure 

good; breakage good; long, large pieces; good, hard, heavy coke, with exception of f-inch black butts, which should.be easily removed; ash high; washing 

would probably reduce ash and improve quality of coke.

Test 139: Light-gray color, some silvery deposit of carbon; good ring; cell structure good; breakage good; long, large pieces; good, strong, hard, heavy coke; 

improved very materially by washing.

Alabama No. 4- Test 131: Light-gray and silv.ery-color; metallic ring; cell structure 

good; breakage somewhat cross fractured, but pieces of good, large, uniform 

size; good, strong, heavy coke; ash high; probably could be reduced by washing. 

Test 136: Light-gray and silvery color; metallic ring; cell structure rather large; 

breakage 'somewhat cross fractured, but pieces of good, uniform size; good, 

strong coke; ash very materially reduced by washing.

Alabama No. 5. Test 171: Light-gray and silvery color; metallic ring; cell structure 

good; breakage good; uniform size; ash and sulphur high, both would probably 

be reduced by washing.

Alabama No. 6. Test 172: Light-gray and silvery color; metallic ring; cell structure 

good; breakage somewhat cross fractured, but pieces of. good, uniform size; 

good, heavy coke.

Test 174: Light-gray and silvery color; metallic ring; cell structure good; breakage 

somewhat cross fractured, but pieces of good, uniform size; good, heavy coke, 

somewhat better than coke from raw coal, but low ash and sulphur of this coal 

would not warrant washing. ' ......_ . .

Arkansas No. 1 B. Test 95: Dull-gray color; soft, dense, punky coke; cell structure

very small; breakage very bad and irregular; large and small chunks. 

Test 96: Dull-gray color; soft, dense, punky coke, with no apparent cell structure; 

drawn from oven in large and small chunks, very easily crushed; test was run 

slowly and high enough heat was not obtained, which accounts for the large 

percentage of breeze. 

Test 97: Dull-gray color; soft, dense coke; cell structure small; better than coke

from washed coal.

Test 100: Dull-gray color; soft, dense, punky coke; possibly little better than 

coke from this coal, with addition of 10 per cent of pitch.

Arkansas No. 7 B. Test 104: Dull, dark color; very soft, light-weight coke; no apparent cell structure; drawn from oven in large and small lumps; bottom 6 inches 

did not coke, burning to ash, all volatile being expelled, but did not stick 

together.

Test 105: Soft, dense, punky coke; drawn from oven in large and small chunks; 

somewhat better and heavier than coke from coal containing no pitch.

Arkansas No. 9. Test 98: No coke produced; charge ashed over top and down about 5 inches. ," " - ---- -- --
COKING TESTS. 37

Arkansas-No. 9. Test 99: No coke produced; ashed down about 4 inches. 

: Test 101: No coke produced; ashed down about 6 inches.

Test 102: Soft, dense, punky coke; drawn from oven in large and small chunks. . 

Test 103: Soft, dense, punky coke; drawn from oven in large and small chunks;

high yield-of breeze, due to large amount of coal whose volatile was expelled,

not sticking together; 5 per cent of pitch not sufficient .for this coal. 

Georgia No. 1. Test 173: Poor, dense coke; large pieces of irregular size; ash high;

probably reduced ash and materially improved by washing. 

Illinois No. 7 D. Test 1: Good, hard coke with medium cell structure; breakage

straight and long. This was the first charge after firing ovens, and results were

not as good as might be expected. 

Test 4: Light-gray and silvery color; metallic ring; cell structure good; breakage

somewhat marred by cross fracture, but pieces'of good size; good, strong coke,

much improved by washing. 

Illinois No. 11 D. Test 5: Light-gray and silvery color; metallic ring; cell structure

good; breakage, good long pieces; good, strong coke. 

Illinois No. 18. Test 2: Dull-gray color; cell structure good; breakage marred by

cross fracture, probably due to successive charging of small portions. 

Test 3: Dull-gray color; cell structure small; cross breakage more pronounced than 

from washed coal.

Illinois, No. 16. Test 7: Accident to charging larry necessitated discontinuing test.

Coal burned to keep oven hot. 

Test-10: Dull-gray color; cell structure small.

Illinois No. 19 .4. -Tests 11, 15, and 19: No coke produced; the whole charge was 

burned and volatile was expelled, but the residue would not bind together.

Illinois No. 20. Test 106: Dull-gray color; cell structure small; breakage bad; separate and distinct cross fracture all over oven, coking in layers; ash and sulphur 

high.

Test 107: Dull-gray color; some little deposit of carbon; .metallic ring; cell 

structure small, but not dense; breakage somewhat marred by cross fracture; 

pieces of good size; great improvement over former test; ash and sulphur high.

Illinois No. 21. Test 126: No coke produced.

Test 137: Burned very vigorously for 12 hours, afterwards falling off rapidly to small 

candles all over surface of charge; when pulled, after 45 hours, product was mixture of unburned coal and slightly coherent mass of coal of original size showing 

no trace of cell structure; all volatile apparently expelled.

Illinois No. 22 B. Test 117: Dull-gray color; cell structure medium; breakage very 

irregular, probably owing to high amount of slate; poor coke; heavy clinker 

over whole surface; ash and sulphur high.

Test 118: Light-gray color; upper 12 inches fingered, two 6-inch sections below 

in chunks; upper 12 inches had metallic ring and good cell structure; the remaining coke poor. This oven was held 72 hours on account of accident. Under 

more favorable conditions, the whole charge would have probably been better 

coke. Ash and sulphur high.

Illinois No. 23 A. Test 111: Light-gray color; some silvery deposit of carbon; cell 

structure a little large; breakage large-fingered pieces; metallic ring; ush and 

sulphur high.

Illinois No. 23 B. Test 112: Light-gray color; a little silvery deposit of carbon; metallic ring; cell structure a little large; breakage, long, thin pieces; larger charges 

would probably make better coke; ash and sulphur high.

Test 114: Light-gray color; a little silvery deposit of carbon; metallic ring; cell 

structure good; breakage, long, thin pieces and large 6-inch chunks; bottom 

very hot; bottom 6 inches probably coked upward; ash and sulphur high.
38 WASHING, COKING, AND CUPOLA TESTS.

Illinois No. 24 A. Test 119: No coke produced; ashed down about 4 inches.

Test 155: No coke produced; all volatile driven off; high heat of by-product ovens 

quickly applied might produce coke.

CONCLUSIONS.

It is unfortunate that the necessary routine' work in order to cover 

so many coals permitted so few tests on each, and that the supply 

of coal in many cases permitted only one test to be made on that particular coal. The data here presented show the results' obtained 

under the best conditions possible to one not conversant with the 

burning -of these coals, based on observations made from time to 

time.as coking proceeded. These facts should be distinctly'borne 

in. mind when analyzing the results here presented. It is hoped 

that in future work it may be possible to vary conditions, make 

changes as they suggest themselves, and compare results on many 

different tests of the same coal and thus draw conclusions of a more 

definite nature. It is to be regretted that no comparisons can be 

made between beehive and by-product coke, but the nature of the 

work here recorded and the facilities provided confined operations 

to ovens of the beehive pattern exclusively.

No data are given in the detailed statement for compressive strength 

or height of furnace burden supported, as the results obtained" show 

conclusively the worthlessness of these determinations. This' conclusion was reached after careful attempts to obtain results on 1-inch 

cubes. Four cubes were selected from each coke made, care being 

taken to obtain pieces with no fracture and representing as nearly 

as possible the average of the coke. The cubes were cut by means 

of an emery wheel and guide, and although by no means perfect 

they were as nearly so as possible and always the two sides used in 

the machine were parallel. The machine used for breaking was a 

Tinius Olsen patent machine of 10,000 pounds capacity and gave 

direct readings of the ultimate strength. '

Only a few of these results, taken at random, are given, and these 

only to show their great variation and the worthlessness of this 

method of drawing conclusions. Illinois No. 16, test 10, 910 pounds, 

1,330 pounds, 2,190 pounds, and 2,270 pounds; Indiana No. 4, test 6, 

640 pounds, 790 pounds,-1,060 pounds, and 1,245 pounds; Kentucky 

No. 1, test 76, 880 pounds, 1,0.65 pounds, 1,920 pounds, and 2,570 

pounds; Ohio No. 9, test 94, 535-pounds, 890 pounds, 1,170 pounds, 

and 1,600 pounds; Virginia No. 1, .test 68, 740 pounds, 1,120 pounds, 

1,280 pounds,: and. 2,060 pounds; West Virginia No. 16, test 49, 

520 pounds, 1,500 pounds, 1-,7.80 pounds, and 2,100 pounds.

The difficulty of obtaining a cube, or any number of cubes, to represent anything more than the piece of coke from which it is taken is so 

apparent that results pretending to show compressive strength of any
46 WASHING, .COKING, AND CUPOLA TESTS.

amount of coke are worse than useless in fact, misleading. Even 

if coke is selected the whole height of the charge and tests are made 

on cubes in number representing the number of inches the results 

still show only the strength of the one piece of coke from some particular part of the oven and it is practically impossible to procure 

even approximately similar results from other pieces taken from 

different places. The condition of burning, the quenching either 

inside or out, and any number of factors which it is not possible to 

know, much less control, make different portions of the same oven 

vary greatly.

A simple calculation will show that coke with a compressiye 

strength of 48 pounds will support the burden of any modern furnace; 

consequently this test gives no data of practical value. Moreover, 

there are so many other factors, such as action of heat and gases, attrition of coke against coke, against other ingredients of charge/ and 

against the side walls, etc., that any calculation to show the burdenbearing capacity of the coke, even if it were possible to select cubes 

representing the whole charge, would be inaccurate if based simply 

on a compression test.

An endeavor was made to compare the different cokes by approximating the amount of breakage under conditions of present-day 

handling, showing the percentage of coke over 2-inch size that may be 

expected to reach the top of the charge in the blast furnace. Fifty 

pounds of each coke were selected, as nearly as possible representing 

the average size of the coke after handling at the ovens. This coke 

was dropped a distance of 6 feet onto a rigid (1-inch) iron plate. All 

pieces over 2 inches in size were weighed and again dropped, the 

operation being repeated three times. The results of these drop tests 

are shown in the detailed statement.

The yield of coke appears to be increased and the amount of breeze

reduced by preliminary crushing. Whether there is a limit to the 

degree of fineness, or whether a point may be reached beyond which 

finer crushing gives no appreciable improvement or has opposite 

effects, can not be determined from the present results; but the data 

available indicate that it would be economical to crush all coal before 

charging into the ovens, even though a coke of good quality may be 

obtained without this preliminary treatment. Fine crushing also 

appears to increase the strength of the coke and make the fracture 

less irregular, by the greater uniformity and distribution of the ash, 

but the weight per cubic foot is reduced. The strength of the coke 

is probably influenced by the amount, composition, and distribution 

of the ash, but the results so far obtained show no definite relations 

between these factors or their relative importance.

The matter of investigating the action of C02 on red-hot coke as 

determining its value for furnace work was thoroughly considered.
COKING TESTS. 47

The conclusion was reached that it was of no practical importance, as 

there are so many other factors in the blast furnace. In view of the 

fact that the gases in the furnace are mixtures of C02 , CO, H, 0, N, 

water vapor, and probably others, it appears that action of CO2 

is of little value unless the action of these other gases, either independently or in connection with C02 , is known. An investigation of 

the action of CO2 on red-hot coke, as a means of making comparison, 

of hardness, is being made and gives evidence of yielding some positive 

results, but work along this line has not progressed far enough to 

draw any definite conclusions.

The loss of sulphur from coal to coke by volatilization varies with, 

the different coals, depending on several factors, among which, in the 

order of their importance, are the condition in which sulphur exists 

in the coal, the heat of the oven, the rapidity of coking, and watering. 

The sulphur loss ranged from 20.79 per cent on Arkansas No. 1 (test 

95) to 63.07 per cent on Illinois No. 29 (test 170), the average for all 

tests being 43.27 per cent.
CUPOLA TESTS OF COKE.

By RICHARD MOLDENKK. '

EQUIPMENT.

Owing to the removal of one of the cupolas which served for the 

foundry tests during the Louisiana Purchase Exposition all the tests 

made since then have been.conducted in the 36-inch foundry cupola 

loaned by the Whiting Foundry Equipment Company, of Chicago. 

The remaining apparatus was rearranged and the 36-inch shell of the 

cupola was relined to 26 inches internal diameter. There were four 

horizontal tuyeres measuring 4 by 6 inches on the outside and 3 by 13 

inches on the inside of the cupola which' were situated 11 inches above 

the sand bottom. The total tuyere area was 96 square inches, giving 

a ratio of Tto 5.96 with the cupola area. A No. 6 Sturtevant fan run 

at 2,514 revolutions per minute furnished the blast, which was kept 

at about 7 ounces.

By proper training, the crew was able to run off two heats a day 

without interruption. The melted iron was poured into molds for 

sash weights, thus reducing to a minimum the amount of scrap made.

PERSONNEL.

The cupola tests were conducted by W. G. Ireland, under the 

direction of A. W. Belden, coke expert of the Geological Survey, and 

by the advice of Richard Moldenke, foundry expert in charge of the 

cupola tests of the fuel-testing plant.

METHOD OF TESTING.

The method of testing has been fully described in the report of the 

fuel-testing plant for 1904.° Toward the end of the tests it was sometimes necessary to vary the proportion of scrap to pig iron according 

to the supply, but the total amounts were kept correct as planned for 

the general series of tests.

After completing the tests on the available cokes in the regular 

way, so that the results might be comparable with the previous work

oProf. Paper U. S. Qeol. Survey No. 48, part 3,1906, pp. 1367-1370. - 

48
CUPOLA TESTS OF COKE. 49

of the division, a series of further tests was made on some of these 

cokes. In these tests the coke bed was not kept at a constant height 

above the tuyeres, but the carbon content was calculated from the 

.analysis of the particular coke and an amount taken to make up 175 

pounds of carbon regardless of the height above the tuyeres. The 

results show interesting features. Some cokes gave melting ratios 

and melting rates per hour which were better than with the ordinary 

test methods and others gave inferior results. The tests were made 

to show the advisability on the part of the manufacturer as well as 

of the foundryman of studying the conditions of cupola practice in 

order to determine those which give the best results.

D'ETAILED RESULTS.

The detailed results of the regular tests as well as of the special 175- 

pound carbon bed tests will be found in the following tables. Results 

of a typical test of Connellsville 72-hour coke are given at the head of 

the first table as a standard for comparison. All the tests here 

reported were made within the calendar year 1906 except test 190, on 

coke from Pennsylvania No. 21 coal, the date of which was February 

13, 1907. Many of the coals tested, however, were received during 

1905.
