CONVEYANCE & DISCHARGE
Year: 1884

page_text: At the top of hot air chamber are fixed three or more outlets or port holes for
discharging the heat.
GAS CONVEYANCE & DISCHARGE,
There are two or more seperate air tight flues carried from the gas producer
right across the hot air chamber which convey the gas (evolving from the fuel) to
the point of contact with the heat at top front of aforesaid hot air chamber when
it instantanously ignites and attains perfect combustion by passing through and
around the interior of furnace chamber.

CUADRAZZIC WEAL CORREC
GAS PRODUCER.
The gas producer is made large enough to hold and contain sufficient gas for a
regular supply according to size of furnace chamber.
The aforesaid producer is built to incline from roof to grate bars at an angle
of 60 to 70 degrees the fuel descends down to grate bars from a door placed against
the centre end near the top of the aforesaid gas producer roof.
To the aforesaid door is attached an hopper which is placed convenient for
workmen to fill to feed the gas producer with fuel.
The aforesaid door works in a groove acted upon by a lever and is made air tight
an aperture is made in the centre of gas producer roof fitted with a small lid for
the purpose of solidifying the fuel when required also of cooling down the aforesaid
gas producer if required at any time.
The fire grate bars are open to the atmospheric air.
SPECIALITIES.
The specialities claimed by our Invention in the improvement of furnaces, kilos
stoves or ovens are as follows:
Firstly. The direct process of conveying the gas.
Secondly. The brick passages or flues for conveying the heat and air utilizing all
waste heat.
Thirdly. The small air valves placed around the furnace and gas producer
thus giving an equal distribution of-air.
Fourthly. The chequered partitions across flues and draughts preventing cutting
currents.
Fifthly. The abatement of the smoke nuisance.
The fundamental aim and object in view with our Invention is the utilization of
heat for the purpose of consuming the gas arising from the fuel.

Sheffield do hereby declare the nature of our Invention for AN IMPROVEMENT IN
FURNACES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The improvements consist in supplying naturally compressed air into sheet iron
or cast metal valves to which lids are fixed that they can easily be regulated by
workmen and placed easy of access at flues and grates of furnaces. The aforesaid air
is quickly conveyed into hot air passages where it becomes heated in transit to the
hot air chamber which is placed between chamber of furnace, and gas producer or
grate the said chamber for hot air is made sufficiently spacious to receive the
heated air and midway along is fixed a chequered partition to steady the incoming
currents of air which arises to top of hot air chamber and are discharged through
openings proportionately made.
The aforesaid air valves are placed in position easily accessible by workmen to
regulate them by opening or closing of lids attached to the said air valves. The
atmospheric air is conveyed into brick passages one each side of flue of the furnace
also one each side or end of gas producer as shown by arrows in Fig. 4 the
air is instantanously conveyed along the aforesaid passages to the air heating
chamber which is built between the gas producer and furnace hearth the air heating
chamber aforesaid is made spacious with a chequered partition built midway along
and extending upwards to the roof-see Fig. 5. At the top of chamber aforesaid are
fixed outlets or port holes for discharging the heated air--see Fig. 10. Furthermore
there are two or more seperate air tight flues carried from gas-producer and across
the air heating chamber which conveys the gas evolving from the fuel to the point
of contact with the heated air at top front of chamber aforesaid when it ignites
and attains perfect combustion whilst passing through and around the interior of
furnace chamber into a chequered partition extending across the neck of furnace
and upwards to the roof-see Fig. 8.
The escaping heat passing through the chequered partition is caught from behind
by passages one each side of flue diverging into the atmospheric air passages which
conveys it to the air heating chamber as shown by arrows in Figure 4.
The gas producer is built large enough to hold and contain the gas and made to
incline from roof to grate bars at an angle from 60 to 70 degrees. The fuel descends
down the aforesaid incline on to grate bars from a door placed against the centre
end near the top of gas-producer roof to which is attached an hopper placed
conveniently for workmen to fill with fuel when required the whole are made
air tight when closed the fire grate bars are open to the atmospheric air—see
Figure 6.

Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed, we declare that what
we claim are
1 The method of conveying the gas direct from the producer to the furnace
hearth substantially as described and illustrated.
2nd The brick passages in the walls of the furnace for air and part of the heated
products of combustion with inlet valves round the furnace arranged substantially
as and for the purpose described.
3rd The chequered partitions in an air heating chamber between the gas-producer
and the furnace hearth, and across the neck or flue end of the bed of furnace,
substantially as and for the purpose described.
