Results

Testing of ArcelorMittal's pellet indurating furnace waste gas stacks began on March 11, 2008 and

continued until March 22, 2008.

There were several significant interruptions of data collection due to a plant breakdown and testing

equipment failures. An interruption occurred with a plant shutdown on March 14 at 6:30 p.m. and

continued until the plant was restarted and the furnace process stabilized on March 17 at 5:00 p.m.

The primary problems with the test equipment were with the airflow measuring equipment. Several

times moisture migrated into the pitot lines and froze giving false readings. Affected data was

flagged when the problem appeared until the problem was corrected. S02 testing continued with the

NOx RVI tests. Periods of process shutdown and invalidated hours due to instrument failure are

identified in the dataset.

The S02 analyzer located on Stack C (SVO16) failed to continuously output the correct signal to the

data logger. Data was not collected on stack C until March 20 at 1:00 p.m. when stack B S02

analyzer was moved to Stack C. Data interpolation was performed to estimate the S02 concentration

of Stack C from March 11 through March 20 and from March 20 to March 22 on Stack B. A

discussion of the procedure used to estimate the concentrations is provided in Appendix A.

Interpolated concentration data was used to generate Ib/hr emission using measured airflow from that

stack.

Forty-five minutes of acceptable data in an hour was used to represent one hour of valid data as

would be allowed by a CEMS system. This allowed normal daily analyzer drift checks to be

performed without omission of data as long as the procedure could be completed in fifteen minutes.

Similarly, when sample gas filters required changing, the procedure was normally completed in less

than fifteen minutes. These events are identified in the data spreadsheet.

The data collection system used during the test experienced an occasional fault. As a result, the

system recorded a significantly lower value for each parameter during a ten second averaging period.

This error occurred nine times during the testing. In cases where it was obviously a data collection

error, the fifteen-minute average was calculated using fourteen minutes of unaffected data. The result

has a minimal effect on the data as only one minute out of sixty minutes during that hour was

excluded. This exclusion is much less than the fifteen minute exclusion described above.

Process description

ArcelorMittal mines taconite ore (magnetite) and produces iron pellets that are shipped to the

company's blast furnaces in Indiana. The emission sources tested capture the waste gases from the

pellet indurating process.

Concentrate slurry flows to the thickener after which limestone is added for compression strength.

The moisture ofthe concentrate is reduced by disk filters and then mixed with bentonite and

conveyed to balling disks. Green balls produced on the balling disks are discharged to a roll screen to

control the pellet size. The green balls are transferred to an oscillating conveyor and then to a roll

conveyor for additional removal of less than Y4 inch material. The green balls are distributed evenly

across the pallet cars, prior to entry into the pellet furnace. The pallet cars have a layer of fired

pellets, called the hearth layer, on the bottom and sides of the car. The hearth layer allows for even

airflow through the pellet bed and acts as a buffer between the pallet car and the heat generated

through the exothermic conversion of magnetite to hematite.

There is one natural gas fired furnace at ArcelorMittal's taconite plant. The straight grate furnace has

several distinct zones. The first two stages are updraft and downdraft drying zones. The next zones

are the preheat zone and firing zone. The temperature increases as the pellets pass through each zone

reaching a peak in the firing zone. The pellets enter the after-firing zone, where the conversion of

magnetite to hematite is completed. The last two zones are cooling zones that allow the pellets to be

discharged at a temperature of around 120 degrees Fahrenheit. Heated air discharged from the two

cooling zones is recirculated to the first zones ofthe furnace for drying and preheating the green

balls. Off-gases from the furnaces are vented primarily through two ducts, the hood exhaust that

handles the drying and recirculated cooling gases, and the windbox exhaust handles the preheat,

firing, and after-firing gases. The windbox exhaust flows through a multiclone, which protects a

downstream fan, and then is combined with the hood exhaust stream into a common header. The

exhaust gases are subsequently divided into four streams which lead to four venturi rod scrubbers and

exhaust from individual stacks.

Stack testing procedures and methods

The testing was performed from ports meeting EPA Method 1 criteria. Test port location and full

traverse drawings are provided in Figures 1 and 4.

An initial airflow using an S-type pitot was performed using EPA Method 2 criteria at each stack. An

S-type pitot tube was fixed at the point in the stack most representative of the average differential

pressure. A calibrated Dwyer Magnesense gauge was used to read the differential pressure at this

point. Calibrated type "K" thermocouples were positioned in the stack to measure stack temperature.

Calculations of volumetric airflow were made with fifteen-minute average data values for velocity

pressure, temperature, barometric pressure, oxygen and carbon dioxide. Stack gas moisture was

measured using an approximation method (wet bulb-dry bulb technique) from EPA Method 4.

Several daily readings indicated that wet bulb temperatures were consistently one degree Fahrenheit

less than dry bulb temperatures; therefore all subsequent moistures were calculated assuming a wet

bulb one degree less than the measured dry bulb value. A single continuous static pressure sensor

was placed in Stack A but malfunctioned. When the error was discovered static pressures were read

at each stack on March 19 and those values were used for their respective stack airflow calculations

for the entire test. This has little impact on the overall results since the static pressure does not affect

the airflow significantly and changes to static should remain relative to one another.

The oxygen and carbon dioxide concentrations ofthe stack gas were measured at one stack

continuously during the testing, with daily measurements made at the other three stacks. The 02/C02

analyzer was calibrated per EPA Method 3A and was fed a split gas stream off the NOx system. The

oxygen and carbon dioxide concentrations used for calculation of gas stream molecular weights for

the three stacks which had only spot checks were performed using the previous data set average until

another reading was taken.

Sulfur dioxide concentrations were determined using a modified EPA Method 6C. Protocol 1 gas

standards were used for daily instrument calibration, system bias checks. Analyzers were calibrated

at the beginning of the project and after the plant shutdown. No intermediate instrument calibration

adjustments were performed. The upper span gas used to determine maximum drift and system bias

was 18.4 ppm S02. A single system bias was performed at the beginning of the project for each

analyzer system. Subsequent calibrations were performed at the analyzers to conserve time on the

NO x data collection. No bias corrections were made to the S02 data.

A Campbell Scientific CRI 000 with multiplex board data logger system was used to record the

output signals from the differential pressure gauge (pitot), stack thermocouple, S02, oxygen, carbon

dioxide concentrations and ambient temperature. The data logger was programmed to collect data

every ten seconds and generate one-minute and fifteen-minute averages. Four fifteen-minute

averages were averaged to make one-hour averages. Data was averaged into hourly values two ways.

One approach was to maximize the number of valid one-hour data points within the data set, the

other was to obtain on the hour averages to coincide with process data. Both versions are in the

spreadsheet.

Method Used for S02 Data Replacement

ArcelorMittal Minorca Mine

Furnace Line Waste Gas S02 Testing

Estimated values were used during times ofinvalid data on stacks B and C. These values

were generated by determining the relationship between stacks [Ex: (BID), (BIA), (CID),

and (CIA)] during times of valid data. Using these relationships we extrapolated values

for Band C based on A and D independently. These values were averaged to determine

our estimate. The complete data set, including estimated data, was graphed to determine

accuracy ofthe representation.

Method 3A Determination of Oxygen and Carbon Dioxide Concentrations in

Emissions from Stationary Sources. A calibrated analyzer will be

used to check the oxygen and carbon dioxide levels daily. The

analyzer will continuously record from one of the sources and will

be used as an indicator of significant change in the oxygen and

carbon dioxide concentrations.

Method 4 Determination of Moisture Content in Stack Gases. Daily wet

bulb/dry bulb readings will be taken. In the event the sources are

consistently saturated, further moisture calculations will assume

saturation at the average stack temperature.

Method 6C Determination of Sulfur Dioxide Emissions from Stationary

Sources. The measurement of S02 concentration will be

performed simultaneously at all four stacks following EPA Method

6C. The method performance will be modified by collecting data

over up to 150 hours of representative plant operation. All

analyzers will be calibrated initially for linearity and daily for zero

and span checks. Data will be considered to be valid it drift is

within the limits for a normal CEM system. Instruments will read

All tests will be performed using the following USEPA reference test methods. 

Pollutant, Test Method1 

parameter 

SOx, Method 1 Sample and Velocity Traverses for Stationary Sources. Twelvevolumetric point traverse for selecting representative point for continuous 

air flow rate, monitoring 

temperature Method 2 Determination of Stack Gas Velocity and Volumetric Flow Rate. 

and moisture An US" type pitot tube fixed at a representative point in each stack. 

Differential pressure recorded with one minute and one hour 

averages in inches of water. 

Stack temperature using a type K thermocouple, recorded with 

one minute and one hour averages in of. 

Method 3A Determination of Oxygen and Carbon Dioxide Concentrations in 

Emissions from Stationary Sources. A calibrated analyzer will be 

used to check the oxygen and carbon dioxide levels daily. The 

analyzer will continuously record from one of the sources and will 

be used as an indicator of significant change in the oxygen and 

carbon dioxide concentrations. 

Method 4 Determination of Moisture Content in Stack Gases. Daily wet 

bulb/dry bulb readings will be taken. In the event the sources are 

consistently saturated, further moisture calculations will assume 

saturation at the average stack temperature. 

Method 6C Determination of Sulfur Dioxide Emissions from Stationary 

Sources. The measurement of S02 concentration will be 

performed simultaneously at all four stacks following EPA Method 

6C. The method performance will be modified by collecting data 

over up to 150 hours of representative plant operation. All 

analyzers will be calibrated initially for linearity and daily for zero 

and span checks. Data will be considered to be valid it drift is 

within the limits for a normal CEM system. Instruments will read 

PPM dry. 1 All test methods and are found In 40 CFR 60 Appendix A

Arcelor Mittal and Barr Engineering contacts will make themselves available for a pretest

meeting prior to March 3. At the preference ofthe MPCA, ArcelorMittal suggests the pretest

meeting be conducted by telephone.

Maintenance: A description of any necessary work done within 30 days prior to the test and the

normal maintenance schedule followed will be included in the test report.

Test Reports: One hard copy ofthe test report will be submitted to the MPCA. ArcelorMittal

requests that the required test report submittal be extended to 60 days following test completion

because ofthe large volume of data to be processed and summarized. SOx emissions

concentration data and calculated emissions rates will be submitted on CD-ROM in a nonprotected spreadsheet format (Excel).
