IMPROVEMENTS IN GAS PRODUCERS
Year: 1884

page_text: I, GEORGE ROBERTSON HISLOP, of Paisley, in the County of Renfrew, Gas
Engineer, do hereby declare the nature of my said Invention for "IMPROVEMENTS
IN GAS PRODUCERS"; to be as follows:-
This Invention relates to improvements in the construction of gas producers, and
in means for regulating the admission of air and water vapour thereto.
The improved gas producer consists of an oblong chamber, covered by an arch,
through which the fuel is charged by an opening provided with a door. The floor
of the producer is formed by brickwork built up of slopes or half arches springing
from a central block to the side walls and back end of the oblong chamber, in a
highly inclined manner, and supported upon iron plate. The mass of fuel confined
within the side walls and inclined floor of the producer, thus approximates in cross
section to a triangle, whose base is near the arched roof, and whose apex is in the
centre of the floor. In each side of the inclined floor, near the inner and lower side
of the archway, are fitted a number of openings, cased with metal, which conduct
air into the lower part of the fuel in the producer from the archway beneath the
metal plates. The archway on each side is confined by the piers of brickwork
forming the side walls of the producer chamber; and at the front end of each
archway is fitted a door, provided with a grating, or with similar means of
regulating the admission of air to the archway from which the producer is supplied
with air, through the cased openings in the floor. On the floor of the archway at
each side, is fitted a trough or pan, into which water is caused to trickle through
pipes; and the ashes and clinkers are raked out of the bottom of the producer
through the air openings or ports, into the water troughs, while the water is
vaporised by the heat, and the vapour enters the ports along with the air supply.
A main doorway, provided with an air-tight door, is fitted in the front wall of the
producer, to give access for repairs and raking out clinkers and ash; and access is
obtained to the ash pans or troughs through the doorways by which air is admitted
to the inlet ports. The gases generated from the fuel in the producer are led away
by an outlet or outlets near the arched roof.

page_text: I, GEORGE ROBERTSON HISLOP, of Paisley, in the county of Renfrew, Gas
Engineer, do hereby declare the nature of my said invention for "IMPROVEMENTS
IN GAS-PRODUCERS," 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 improvements in the construction of gas-producers, and
in means for regulating the admission of air and water vapour thereto.
The invention is illustrated by the accompanying drawings, in which figure 1 is
a transverse vertical section, and figure 2 a longitudinal vertical section of the
improved gas producer. Figures 3 and 4 are similar views showing the improved
gas-producer as applied for heating gas retorts.
The improved gas producer consists of an oblong chamber A covered by an
arch A' through which the fuel is charged by an opening B provided with a
door C. The floor of the producer is formed by brickwork built up of slopes or
half arches A springing from a central block A³ to the side walls and back end of
the oblong chamber A in a highly inclined manner, and supported upon iron..
plates D. The mass of fuel confined within the side walls and inclined floor of the
producer, thus approximates in cross section to a triangle, whose base is near the
arched roof and whose apex is in the centre of the floor. In each side of
the inclined floor A³ near the inner and lower side of the archway, are fitted a
number of openings E cased with metal, which conduct air into the lower part of
the fuel in the producer from the archways F beneath the metal plates. The
archway F on each side is confined by the piers G of brickwork forming the side
walls of the producer chamber; and at the front end of each archway F is fitted
an air-tight door H provided with a grating h or with similar means of regulating
the admission of air to the archway from which the producer is supplied with air,
through the cased openings E in the floor. On the floor I of the archway F at
each side, is fitted a trough or pan J, into which water is caused to trickle through
pipes j; and the ashes and clinkers are raked out of the bottom of the producer
through the air openings or ports E into the water troughs J, while the water is
vaporised by the heat, and the vapour enters the ports E along with the air supply.
A main doorway K, provided with an air-tight door K¹ is fitted in the front wall
of the producer to give access for repairs, and for occasional raking out of clinkers
and ash; and access is obtained to the ash-pans or troughs J through the
doorways H by which air is admitted to the inlet ports E. In lieu of permitting
the air and water vapour to enter the ports E by natural draught, air and steam
may be forced through the archways F into the ports E to accelerate combustion
of the fuel within the producer chamber A, the doors H and air openings being in
such case closed air-tight. Such forced combustion is especially applicable when
Black, breeze, or other inferior fuel is used. The gases generated from the fuel in
the producer, are led away by an outlet or outlets L near the arched roof A¹ to the
point where the heat is to be applied. In figures 3 and 4, the outlets L through
which the gases pass from the producer are connected to the combustion chamber M
provided in connection with a series of gas retorts N enclosed within a chamber (
through which the burning gases circulate, the combustion of the gases in the
chamber M being effected by introducing air which has been previously heated by
traversing a series of regenerator flues P in which the air travels backward and
forward as shown by the arrows before entering the combustion chamber by the
ports p while the waste gases travel in the opposite direction through central
flues on their way to the chimney.

page_text: 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,―
First. The arrangement or combination of parts forming the improved gas
producer herein described and illustrated.
Second. A gas producer consisting essentially of a chamber, the floor of which is
formed by arches springing from the centre or near the centre to the side walls,
such arches being supported by metal plates and pierced or formed with cased
ports for the admission of air and water vapour, substantially as herein described
and illustrated.
Third. The arrangement in a gas-producer of the arched chamber F provided
with air admission and regulating doors, capable of being made air tight, substantially
as herein described and illustrated.
