IMPROVEMENTS IN THE PRODUCTION OF COMBUSTIBLE GASES FROM FINELY PUL- VERIZED COAL, PEAT, WOOD SAWDUST, OR OTHER MATERIAL
Year: 1885

page_text: I, FREDERICK, JOSIAH, JONES of "The Bank " Bewdley in the county of
Worcester, Civil Engineer do hereby declare the nature of my invention for
IMPROVEMENTS IN THE PRODUCTION OF COMBUSTIBLE GASES FROM FINELY PUL-
VERIZED COAL, PEAT, WOOD SAWDUST, OR OTHER MATERIAL and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement:―
This invention relates to the production of combustible gases for heating and
illuminating purposes, and consists essentially in passing a regular supply of finely
pulverized coal, peat, wood sawdust, or other suitable material, through an
hermetically closed chamber of suitable construction, provided with the necessary
inlets & outlets & heated to a temperature sufficient for evolving combustible gases
from the materials introduced.
According to one arrangement which is especially applicable to iny purpose, I fix
an ordinary iron gas retort over a furnace provided with a chimney & flues in the
usual manner and I elevate one end of the retort to allow the pulverized coal, etc,
which is there admitted to gravitate to the exit provided at the lower end.
When requisite I insert in a convenient position a pipe for the admission of
superheated steam, or jet of gas, to assist the finely pulverized coal etc, in its
passage through the retort. The finely pulverized coal, peat, wood sawdust, etc is
supplied to the interior of the retort by means of a hopper, mill, or other suitable
contrivance, placed in this particular arrangement at the elevated end of the
retort.
An exit is provided for the carbonized coal, etc, which may be removed from the
receptacle into which it passes by an endless screw or other suitable means for
preventing an inrush of air.
By this method a supply of gas is regularly generated.
And the gas so produced is conducted where required, by pipes & valves suitable
for the purpose.
A proper amount of air may be mixed with the gases, when required for
producing an intense and smokeless heat.
When heated air is required for adding to the gases a pipe is inserted into the
furnace chimney or flues and a supply drawn therefrom.

page_text: The gases produced by this system are available for heating marine and land
steam boilers, and other purposes where a steady and easily regulated heat is
necessary.
The gases may also be condensed for illuminating purposes in the usual way.
The solid residuum of carbonization I utilize as fuel in the furnace heating the
retort.
DESCRIPTION OF DRAWING.
The annexed drawing shews a longitudinal section of one method by which I
propose to carry out my invention. A A. is an ordinary iron gas house retort, closed
at both ends and fixed at such an angle as to allow the pulverized coal, peat, &c,
which enters through the hopper or mill B, to gravitate to the exit pipe C, through
which it passes to the cylinder, or other receptacle D, from whence it is removed
by a revolving screw or other means preventing an inrush of air to the interior of
the retort. E is the pipe provided for the exit of the evolved gases. F is a pipe
for providing heated air for mixing with the gases when requisite. G is the
furnace for heating the retort to gassing temperature. H, H, are the furnace flues.
K is the pipe for supplying super heated steain, or gas under pressure, to assist the
pulverized coal, etc, in passing through the retort. N, is the chimney connected
with the furnace G.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
The production of combustible gases by passing finely pulverized coal, peat wood
sawdust or other suitable material through a highly heated and air tight chamber
or retort, of suitable form and material, substantially as described.
