Improvements in Gas Producers.
I, CHARLES DENTON ABEL, of No. 28 Southampton Buildings, Chancery
Lane, in the County of London, Consulting Engineer and Chartered Patent
Agent, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved construction of gas producers whereby
strongly slagging or caking fuel, such as coke, can be used for the manufacture of
combustible gas with the same facility as anthracite, inasmuch as it permits of a
rapid and effectual clearing of the producer chamber from the accummulated slag
or caked material. .
In addition, the improved construction of gas producer enables a variation
between wide limits of the quantity of gas produced to be effected without in any
was altering the quality thereof.
I will describe the construction of the improved gas producer with reference to
the accompanying drawings in which
Figs. 1 and 3 shew vertical sectious of the gas producer at right angles to each
other;
Figs. 2 and 4 shew cross sections taken respectively on lines c d and a b.
A is the producer chamber, built of fire brick J; C is the charging hopper,
closed by a double valve; B is the discharge pipe for the gas, R is the grate,
and L is the ashpit.
The supply of air and steam is effected by means of several injectors V V₁ V".
Each injector is supplied with steam through a pipe M and nozzle N, the steam jet
being made to carry the air along with it so as to enter in combination therewith
through the pipe Z into the ashpit below the grate.
The mixture of air and steam in penetrating through the grate among the
incandescent fuel above the same, and in decomposing the fuel, forms therewith
the producer-gas composed mainly of carbonic oxide, hydrogen and nitrogen in
the well known manner, which gas passes off through the pipe B to wherever
required.
In order to enable the slag or caked material that adheres to the sides of the
chamber H to be readily removed, the lower part thereof H is enlarged to a
rectangular form, this being effected to the height to which the adhesion of the slag
can take place.
On opposite sides of this enlarged part are formed rectangular openings of the
full width, and to these openings are fixed cast iron frames with doors G G of the
same size as the openings, which doors are made to close air tight. In order to
ensure the maintenance of such airtight closure, notwithstanding the intense heat
of the bottom layer of fuel, protective shields F lined with firebrick like the
doors Gare slid into the openings H in front of the doors, so as to leave a non
conducting body of air between the two. On opening the doors G and withdrawing
the shields F, the accummulated slag can be readily detached from the grate and
sides of the chamber, and removed through the openings.
The doors D to the ashpit serve for the removal of the ashes.
The employment of several injectors V V V has for its object to regulate the
quantity of gas produced according to requirements, by putting one or more thereof
into or out of action. By this means a much more perfect regulation can be

page_text: obtained than by the usual method of throttling the steam supply, because by such
variation of the steam jet the air supply is not increased or decreased in the same
proportion as the quantity of steam, and consequently the most benefial proportion
of air and steam is not maintained.
With the above described improved arrangement, on the other hand, the volume
of steam and air of each injector is maintained constant and consequently, whether
one or several injectors are put in action, the most beneficial proportions of the air
and steam are always maintained.

Improvements in Gas Producers.
I, CHARLES DENTON ABEL of No. 28 Southampton Buildings Chancery Lane
in the County of London, Consulting Engineer and Chartered Patent Agent, do
hereby declare the nature of this invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement thereof:-
This invention relates to an improved construction of gas producers whereby
strongly slagging or caking fuel, such as coke, can be used for the manufacture of

caked material.
In addition, the improved construction of gas producer enables a variation
between wide limits of the quantity of gas produced to be effected without in any
way altering the quality thereof.
will describe the construction of the improved gas producer with reference to
the drawings accompanying my Provisional Specification in which Figs. 1 and 3
shew vertical sections of the gas producer at right angles to each other; Figs. 2
and 4 shew cross sections taken respectively on lines c d and a b. A is the producer
chamber, built of fire brick J; C is the charging hopper, closed by a double valve;
B is the discharge pipe for the gas, R is the grate, and L is the ashpit.
The supply of air and steam is effected by means of several injectors V V₁ V".
Each injector is supplied with steam through a pipe M and nozzle N, the steam jet
being made to carry the air along with it so as to enter in combination therewith

In order to enable the slag or caked material that adheres to the sides of the
chamber A to be readily removed, the lower part thereof H is enlarged to a
rectangular form, this being effected to the height to which the adhesion of the
slag can take place.
On opposite sides of this enlarged part are formed rectangular openings of the
full width, and to these openings are fixed cast iron frames with doors G G of
the same size as the openings, which doors are made to close airtight. In order to
insure the maintenance of such airtight closure, notwithstanding the intense heat of
the bottom layer of fuel, protective shields F lined with firebrick like the doors G

the chamber, and removed through the openings.
The doors D to the ashpit serve for the removal of the ashes.

Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
1. A gas producer whose chamber A is enlarged to a rectangular shape at the
lower part H and is there provided with two opposite doors G G of the full width
of the chamber for the purpose of enabling the slag or caked material adhering to
the sides of the chamber to be readily removed, substantially as described.
2. In a gas producer constructed as set forth in the preceding claim, the use of
loose protecting shields F F placed in front of the doors G G so as to leave a
protective body of air between the two substantially as described.
3. In combination with a gas producer such as is herein referred to, the use of
two or more steam jet injectors V V₁ V" any one or more of which are put in or
out of action for the purpose of increasing or decreasing the quantity of gas to be
produced, substantially as described.
