PROVISIONAL SPECIFICATION.
Improvements in Gas Producers.
I, JOHN BROMILOW, of Ivy House, Pontymister, near Newport, Monmouth-
shire, Steel Works Manager, do hereby declare the nature of this invention to be
as follows:-
:-
The first part of the invention relates to the application of steam and atmospheric
air in the production of what is known as producer gas as used for the raising of
high temperatures in regenerative and other furnaces, and consists in an arrange-
ment of valves in two sets so that the largest possible amount of steam can be
decomposed in proportion to the amount of fuel used thereby effecting a considerable
saving in fuel and labour.
These valves are connected with steam pipes and regulating boxes, through which
the steam and atmospheric air pass before entering a larger pipe in which they are
mixed before coming in contact with the solid fuel intended to be converted into
gas, and are so arranged that a large proportion of steam or air can be admitted on
either side of the producer as hereinafter explained.
An ordinary steam valve is fixed in each steam pipe, above the regulating
boxes, in order to admit the quantity of steam necessary for the working of the
producer.
At the bottom of each steam pipe is fixed a nozzle the orifice of which is
placed a few inches below the slide or throttle valves in the regulating. boxes.
These valves and boxes are intended to regulate the quantity of atmospheric.
air required to work the producer and maintain the requisite temperature in
the mass of solid fuel with which the producer is filled.
By this arrangement of two sets of regulating valves a large proportion of
air can be forced into one side of the producer and on. the opposite side a large
proportion of steam can be allowed to enter.
The two sets of valves can be arranged so that they can be reversed, in
order to render the producer continuous and regular in its working, by means of
connecting rods and a lever.
The second part of the invention consists in the improved construction of the
bottom of the producer by dividing it into two parts by means of a brick wall
which is carried up a few inches above the door frames thus forming two
separate pockets at the bottom and a little below the level at which the mixed
gases enter and come in contact with the solid fuel with which the producer is
filled.
These pockets also form a convenient receptacle for the deposit of the residue
in the form of clinker formed by the incandescent fuel in its descent while
being converted into gas. The division wall which is built in the middle and
between the back wall and door frames also forms a convenient rest for the solid
fuel above while the clinkers are being removed from the pockets below.
Above the two chamber pockets thus described, and immediately above the
division wall a large rectangular chamber is formed in brickwork by sloping the
four sides thus providing a large area at the top of the producer in order to
allow of free distillation of the solid fuel into gas. The solid fuel is charged
through two separate hoppers placed at the top of the producer in the ordinary
manner.

Improvements in Gas Producers.
1, JOHN BROMILOW, of 137 Warwick Road, Birmingham, Steel Works
Manager, 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 :--
The first part of the invention relates to the application of steam and atmospheric
air in the production of what is known as producer gas as used for the raising of
high temperatures in regenerative and other furnaces, and consists in an arrange-
ment of valves in, two sets so that the largest possible amount of steam can be
decomposed in proportion to the amount of fuel used thereby effecting a considerable
saving in fuel and labour.
These valves are connected with steam and regulating boxes, through which the
steam and atmospheric air pass before entering a larger pipe in which they are
mixed before coming in contact with the solid fuel intended to be converted into
gas, and are so arranged that a large proportion of steam or air can be admitted on
either side of the producer as hereinafter explained.
An ordinary steam valve is fixed in each steam pipe, above the regulating
boxes, in order to admit the quantity of steam necessary for the working of the
. producer.
.
At the bottom of each steam pipe is fixed a nozzle the orifice of which is placed a
few inches below the slide or throttle valves in the regulating boxes. These valves
and boxes are intended to regulate the quantity of atmospheric air required to work
the producer and maintain the requisite temperature in the mass of solid fuel with
which the producer is filled.
By this arrangement of two sets of regulating valves a large proportion of air
can be forced into one side of the producer and on the opposite side a large
proportion of steam can be allowed to enter..
The two sets of valves can be arranged so that they can be reversed in order to
render the producer continuous and regular in its working, by means of connecting
rods and a lever.
The second part of the invention consists in the improved construction of the
bottom of the producer by dividing it into two parts by means of a brick wall which
is carried up a few inches above the door frames thus forming two separate pockets
at the bottom and a little below the level at which the mixed gases enter and come
in contact with the solid fuel with which the producer is filled.
These pockets also form a convenient receptacle for the deposit of the residue in
the form of clinker formed by the incandescent fuel in its descent while being
converted into gas. The division wall which is built in the middle and between
the brickwall and door frames also forms a convenient rest for the solid fuel above
while the clinkers are being removed from the pockets below.
Above the two chamber pockets thus described, and immediately above the
division wall a large rectangular chamber is formed in brickwork by sloping the
four sides thus providing a large area at the top of the producer in order to allow
of free distillation of the solid fuel into gas. The solid fuel is charged through
two separate hoppers placed at the top of the producer in the ordinary manner.
I will now describe my invention with reference to the accompanying drawings
which are to be taken as part of this Specification and read therewith.
Figure 1 is an elevation and Figure 2 a vertical section of my improvement in
gas producers and
Figure 3 a cross section of same.
The same letters of reference indicate similar parts in all the figures.
A. A, are the steam pipes connected with the valves and regulating boxes B. B,
through which the steam and atmospheric air have to pass to the solid fuel to be

page_text: C. C, are the steam valves fixed one in either of the steam pipes to regulate the
quantity of steam admitted, necessary for the proper working of the producer.
E. E, are the nozzles fixed at the bottom of each steam pipe A. A, through which
is admitted the quantity of atmospheric air necessary to maintain the temperature
of the solid fuel and regulated by means of the slide or throttle valves F. F, as
hereinbefore described.
G, is the lever and rods for reversing the valves F. F, to maintain a regular and
continuous working of the producer.
H. H, are the two separate chamber pockets referred to in the second part of my
invention which form convenient receptacles for the deposit of clinker.
J. is the division wall constructed as described and forms a conveenent rest for
the solid fuel while the clinker is being removed from the pockets H. H.
K, is the rectangular chamber over the pockets at the top of the producer for
allowing free distillation of the solid fuel into gas.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The arrangement of valves for regulating the quantities of gases, viz., steam
aud atmospheric air required in the production of producer gas and the application
of the arrangement for reversing the same and thereby causing a regular and
continuous working, and consequently double acting, water gas producer, sub-
stantially as herein before described in the first part of my Specification, and
illustrated in the accompanying drawings.
2. The division of the producer at the bottom into two separate chambers or
pockets in one of which nearly pure water gas can be produced, while in the other
part the proper temperature is being maintained by the forcing in of a large
volume of atmospheric air substantially as herein before described and illustrated in
the accompanying drawings.
3. The advantage derived from the arrangement of the wall dividing the bottom
part of the producer, by the supporting of the solid fuel above while the clinker
and ashes are being removed from the pocket chambers below substantially as
hereinbefore described and illustrated in the accompanying drawings.
