BRIERLEY DENHAM HEALEY, of 37 Victoria Street, Liverpool, in the County of
Lancaster, Civil Engineer, do hereby declare the nature of my invention for
IMPROVEMENTS IN MAKING AND WORKING GAS GENERATORS AND UTILISING HEAT
THEREFROM to be as follows:-
My invention has reference to improvements in making and working generators
which are used for converting slack coke coal and wood into gaseous fuel and
utilising otherwise waste heat therefrom.
The lower part of the generator has horizontal firebars resting on suitable
bearers or supports, special bearers at front end over which are driven the falsebars
when removing the clinkers from the firebars, and a central bridge which carries
inner end of firebars and falsebars through which bridge air is admitted from
steam blower to the underside of the firebars.
The ends of the firebar bearers pass through slots in outer casing into boxes in
which screws are provided for lowering the bearers before starting to remove the
The
clinkers, and for raising the bearers after the clinkers have been removed.
said boxes are secured to the outer casing, and the clinkering 'doors are placed on
opposite faces of the firegrate, all of which are air tight.
The ashpit is built nearly rectangular for about twenty inches in height, above
the fire bars the for is circular the inner lining sloping outwards for a short length,
above this it is built vertical up to level of roof springing. The roof is formed of
fireclay slabs set at an angle of about 20° with a central opening through which
the fuel is fed by bell and hopper arrangement somewhat as shewn in the
specification of a patent granted unto me A.D. 1872. No. 85.
The whole is retained within a plate iron casing, and in order fo fully utilise the
otherwise waste heat, I surround the casing with a water jacket, this I encircle by
another annular space through which the gas is conveyed from the top to an
annular main near the bottom of the apparatus, and outside the latter I form an
air space to which I connect the suction of steam blower near the top.

page_text: In a simpler form of apparatus I dispense with the annular water and gas spaces
still using the annular air space, and in the simplest form of apparatus I dispense
with all the annular spaces using air direct from surrounding atmosphere and
taking off the gas by a branch pipe.
The heated water from casing may be used for any purpose for which it is
suitable, and part of the heated air may be used in the combustion of the gas
producer.
Utilising Heat therefrom.
I, BRIERLEY DENHAM HEALEY of 37 Victoriá Street, Liverpool, in the County
of Lancaster, Civil Engineer, do hereby declare the nature of my invention for
IMPROVEMENTS IN MAKING AND WORKING GAS GENERATORS AND UTILISING HEAT
THEREFROM and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention has reference to improvements in making and working generators
which are used for converting slack coke coal and wood into gaseous fuel and
utilising otherwise waste heat therefrom.
The lower part of the generator has horizontal firebars resting on suitable
bearers or supports, and special bearers at front end, over which are driven the
false bars when removing the clinkers from the firebars, and a central bridge which
carries inner end of firebars and false bars, through which bridge air is admitted
from steam blowers to the underside of firebars. The ends of the firebar bearers
pass through slots in outer casing into boxes in which screws are provided for
lowering the bearers before starting to remove the clinkers and for raising the
bearers after the clinkers have been removed. The said boxes are secured to the
outer casing, and the clinkering doors are placed on opposite faces of the firegrate,
all of which are air tight.
The ashpit is built nearly rectangular for about 20 inches in height and above
the firebars the form is circular, the inner lining sloping outwards for a short
length above which point it is built vertical up to level of roof springing.
The roof is formed of fireclay slabs or lumps set at an angle of about 20° with a
central opening through which the fuel is fed by bell and hopper arrangement
somewhat as shewn in the specification of a patent granted to me in 1872 and
numbered 85,

page_text: The whole is retained within a plate iron casing and in order to fully utilise the
otherwise waste heat I surround the casing with a water jacket, this I encircle by
another annular space through which the gas is conveyed from the top to an
annular main near the bottom of the apparatus, and outside the latter, I form an
air space to which I connect the suction of steam blower near the top. In a
simpler form of apparatus I dispense with the annular water and gas spaces still
using the annular air space, and in the simplest form of apparatus I dispense with
all the annular spaces using air direct from surrounding atmosphere and taking off
the gas by a branch pipe.
The heated water from casing may be used for any purpose for which it is
suitable, and part of the heated air may be used in the combustion of the gas
produced.
The accompanying sheet of drawings are intended to form part of this speci-
fication. Figure 1 represents a section of the first type of my producer of which
figure 2 is a plan in section. Figure 3 is a section of the second type of producer.
Figure 4 is a plan in section of the second type of producer one half of which is
taken on line A B the other half on line Û D.
The reference letters where repeated on the various figures refer to the same or
corresponding parts.
Referring to figs. 1 and 2 the annular space a is the water space the gases from
the producer pass through the opening 6 shewn in the arch, and then descend by
the annular space c collecting in the annular main d, from which they are led to
any position desired for use. The outer annular space e is intended for the purpose
of heating the air part of which may be led to the point where combustion of the
gas takes place.
Referring to the type of producer shewn by figs. and 4 it will be seen that
there are two sets of firebars e the inner ends of which are supported by a central
bridge which may be hollow as shewn or of a solid form or plain bars f¹ may be
used as bearers but I prefer the hollow type owing to its greated durability.
The blast of air and steam enters from the blower through the hollow space f of
the bridge and passes into the fuel through the spaces between the firebars and
through the holes g which keep the upper part of bridge from burning away. The
firebars are supported at the front end by bearer bars h which pass through slots
in outer casing into boxes i, in which screws j are provided for lowering the said
bearer bars before commencing to remove the clinkers, and for elevating the bearer
bars after the clinkers have been removed. The said boxes j and the clinkering
doors in which are placed on opposite faces of the fire grate are secured to the
casing and are all made practically air tight. The doors m are provided with
cross bars and screws n. The ashpit o is of a rectangular form for about 20 inches
in height and above the firebars the producer is of nearly octagonal form the inner
lining p sloping outwards for a short length. The corners p' above level of fire-
grate are hatched over by suitable lumps so as to bring the upper part or trunk
of the producer q to a circular form. The roof r is formed of fireclay lumps & set
at an angle of about 20° with a central opening t through which the fuel is fed by
bell and bopper arrangement u. False bars are driven in over the special bearers v
before the clinkers are withdrawn by the use of which the loss of coke in
clinkering is greatly reduced.
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
1st The method of lowering or elevating firegrates substantially as herein shewn
and described.
2nd The arrangement shewn for heating the water and air substantially as
herein shewn and described.
3rd The system of arranging two sets of fire bars and clinkering doors sub-
stantially as herein shewn and described.

page_text: 4th The general arrangement of the several parts substantially as herein shewn
and described.
5th The method of developing the inner lining from rectangular form to
octagonal and then to circular form as herein shewn and described.
6th Using part of the otherwise waste heat from said gas generators for heating 5
the air for the combustion of the gas produced.
