PROVISIONAL SPECIFICATION.
Improved Apparatus for Heating Retorts and for similar purposes.
I, DAVID TERRACE, cf the Corporation. Gas Works, Middlesbrough, in the
County of Yorkshire, Engineer and Manager, do hereby declare the nature of
this invention to be as follows :-
The object of this invention is for heating inclined retorts by what is termed the
regenerative system, as used in gas works, and for similar purposes.
Hitherto the gas producers and regenerator chambers have been arranged in such
a manner that the gases from the producer travel from a lower to a higher level.
where combustion takes place, the products descending through the waste heat flues
in conjunction with the flues containing heated air to support combustion.
In this invention a vertical gas producer is placed at the higher level of the
inclined retorts, immediately outside (or inside), the heating gas from the ports from.
the producer emerging underneath the retorts meeting the heated air, which com-
bines, combustion taking place, filling the inclined chamber, or bed in which the
retorts are placed and travels downwards. The retorts are supported on chequered
walls on stepped covering, (on top of flues and air passages,) in such a way as to.
admit of properly heating retorts without having recourse to tortuous passages or
deflected currents.
The inclined main arches of beds are constructed of small stepped courses to.
secure level springings and general stability.
Ports and surface openings are constructed above producers to facilitate the first.
heating of the beds.
The openings conducting the products of combustion are at the lower end of the
incline, and lead to the chimney through suitable flues, between which are placed
the heated air passages, the air from which is conducted to the higher point to meet.
the producer gas as before described, and is termed secondary air.
The flues containing waste products are preferably taken to large underground.
flue and thence to chimney.
Swivel dampers or other suitable means are employed to control the waste gas
from the regenerators to the main flue. Hinged flap valves or other means are.
employed to regulate the supply of secondary air for combustion.
The steam or moisture under the producers is contained in a tube (or tubes) and.
emerges through round holes or long slit openings. The producers are made
"double
so that one of them is an incandescent state while the other is being.
cleaned and otherwise getting ready for full production of gas.
"
This invention is also applicable to what are termed stage floor houses, that is:-
Where heating arrangements are placed below or near stage at lower end of
retorts.
It will be understood that the foregoing is given by way of illustration and that
the shapes, materials, and parts may be varied in many ways within the scope of my.
invention.

Improved Apparatus for Heating Retorts and for similar purposes.
I, DAVID TERRACE, of the Corporation Gas Works, Middlesbrough, in the
County of Yorkshire, Engineer and 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 object of this invention is for heating inclined retorts by what is termed the
regenerative system, as used in gas works, and other similar purposes.
Hitherto the gas producers and regenerator chambers have been arranged in such
a manner that the gases from the producer travel from a lower to a higher level, or
on the same level, after combustion takes place, the products descending through
the waste heat flues in conjunction with the passages containing heated air to
support combustion.
In this invention a vertical gas producer is placed at the higher level of the
inclined retorts, immediately outside or inside, the heating gas from the ports from
the producer emerging underneath the retorts meeting the heated air, which
combines, combustion taking place, filling the inclined chamber, or bed in which the
retorts are placed, and travels downwards. The retorts are supported on chequered
walls on stepped covering, (on top of flues and air passages,) in such a way as to
admit of properly heating retorts without having recourse to tortuous passages or
deflected currents.
The inclined main arches of beds are constructed of small stepped courses to
secure level springings, and general stability.
Ports and surface openings are constructed above producers to facilitate the first
heating of the beds.
The openings conducting the products of combustion are at the lower end of the
incline, and lead to the chimney through suitable flues, between which are placed
the heated air passages, the air from which is conducted to the higher point to
meet the producer gas as before described, and is termed secondary air.
The flues containing waste products are preferably taken to large underground
flue and thence to chimney.
Swivel dampers or other suitable means are employed to control the waste gas
from regenerators to main flue. Hinged flap valves or other means are employed
to regulate the supply of secondary air for combustion.
The steam or moisture under the producers is contained in a tube or tubes and
emerges through round holes or long slit openings. The producers are made
"double so that one of them is in an incandescent state while the other is being
cleaned, and otherwise getting ready for full production of gas.
"
This invention is also applicable to what are termed stage floor houses, that is :-
-Where heating arrangements are placed below or near stage at lower end of
retorts.
And in order that my invention may be thoroughly understood, I now proceed to
describe the accompanying drawings thereof, reference being had to letters and
figures marked thereon.

Parts of some of the figures are broken off for convenience.

page_text: producers emerging underneath the retorts, meeting the heated air at c with which
it combines, combustion taking place, filling the inclined chamber or bed in which
the retorts are placed. The heat travels downwards through the openings d in
chequered walls d' supporting the retorts, heating same throughout.
The openings e conducting the products of combustion are at the lower end of
the incline and lead to the chimney through suitable flues f, between which are
placed the heated air passages g, the air from which is conducted to the higher
point c to meet the producer gas as before described, this is termed secondary air.
Dampers are employed to control the waste gases from regenerators to the main
flue. Openings k in the furnace door l admit the primary air, and the secondary
air for combustion is regulated on entering the openings m leading to the secondary
air passages 9 by flap valves, in the direction indicated by arrows.
The steam is admitted through furnace flame and is drawn under producers to
relieve clinker in the usual way.

The producers are made double or twins so that one of them is in an
incadescent state while the other is being cleaned and re-filled.
The gases from producers lead through three openings p which are common to.
the twin producer.
A port n is constructed above producers to facilitate the first heating of the beds.
The inclined main arches o of beds are constructed of small stepped courses to.
ensure level springings and general stability.
The flues containing waste products are preferably taken to large underground.
Aflue 9 and thence to chimney, in the direction indicated by arrows.
It will be understood that the foregoing is given by way of illustration and that
the shapes, materials and parts may be varied in many ways within the scope of my
invention.
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. Constructing gas producers with ports or openings at a high level through
which the gases pass into the combustion chamber or into retort setting direct,.
there meeting the heated air (secondary) and producing combustion, the heat
travelling from the top of bed to the bottom gradually, substantially as herein
described and according to the accompanying drawings.
2. The combination or general arrangement of the producers, flues, ports
openings and dampers for carrying the invention into effect, substantially as herein
described and according to the accompanying drawings.
3. Double producers for each oven or bed of retorts; one receiving new fuel
while the other is in an incandescent state, substantially as described.
4. The heat from producers being conducted downwards the full length of the
retorts, impinging against the same and so more effectively heating them on its way
to the flues entering the regenerator, substantially as described.
