PROVISIONAL SPECIFICATION.
Combined Gas Producer and Steam Generator.
We, JAMES MORGAN WHILE, of Barrow-in-Furness, in the County of
Lancaster, Manager of the Barrow Steel Works, and JOHN TIMMINS, of the
said address, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to obviate or mitigate the loss of heat which
occurs in ordinary gas producers, built with plates and brickwork, by radiation,
and also in some cases owing to the gas leaving the producer at a higher
temperature than is required; and our apparatus for this purpose is constructed
to form a combined gas producer and steam generator the walls of the producer con-
stituting the steam generator. Such an apparatus can be constructed in various forms.
According to one arrangement the producer is of a form commonly used that is to
say of cylindrical form at its upper and lower parts and of the form of an inverted
truncated cone at its intermediate part which connects the upper and lower parts
above mentioned; coal being supplied at the top into a hopper either by hand or
by a mechanical device. When the fuel becomes heated it imparts a great
quantity of heat to the steam generator; the gas made by the producer then
passes through an opening in the water containing wall into an enclosed space
surrounding a part of the steam generator and thus assists in generating steam
therein; it then passes through a suitable valve for use in other steam generators
or other furnaces as may be required. The steam generated, passes through
suitable pipes for use where required. The upper part of the steam generator
which constitutes the top of the producer is traversed by four or other convenient
number of vertical pipes closed by lids and which correspond to the usual holes or
openings in a producer for examining or stirring the fire. On the top of the
steam generator are provided the usual mountings.
There is a conical perforated casting containing steam jet apparatus as usual in
a producer, and the bottom is water sealed.

Combined Gas Producer and Steam Generator.
We, JAMES MORGAN WHILE, of Barrow-in-Furness, in the County of
Lancaster, Manager of the Barrow Steel Works, and JOHN TIMMINS, of the
said address, Engineer, 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 to obviate or mitigate the loss of heat by
radiation which occurs in ordinary gas producers, built with plates and brickwork,
and also in some cases owing to the gas leaving the producer at a higher temperature
than is required. Our apparatus for this purpose is constructed to form a combined

generator. Such an apparatus can be constructed in various forms.
In the accompanying illustrative drawings,
Fig. 1 is a vertical section, and Fig. 2 a plan, illustrating a combined gas
producer and steam generator constructed according to this invention.
Fig. 3 is a sectional detail view showing a fuel feeding valve.
In this arrangement the producer A is of a form commonly used, that is to say,
of cylindrical form at its upper and lower parts and of the form of an inverted
truncated cone at its intermediate part which connects the upper and lower parts
above mentioned, coal being supplied at the top into a hopper B, either by hand or
by a mechanical device. The producer is constructed with double walls of plate
metal that form the inner and outer walls of a steam generator C which is closed
at the bottom by a ring C', and at the top by an upward extension of the outer wall.
D is a casing surrounding the intermediate and upper portion of the gas producer
so as to form therewith an annular space D' which is in communication with the
interior of the gas producer A by a lateral opening E extending through the
double walls of the steam generator, and with a gas outlet pipe F controlled by a
valve G. E' is a vertical wall or division arranged between the opening E and
the pipe F so that hot gas escaping through the said opening into the passage D'
must flow completely round the steam generator before escaping into the pipe F.
The upper part of the steam generator, which constitutes the top of the producer,
is traversed by four or other convenient number of vertical pipes H closed by lids
and which correspond to the usual holes or openings in a producer for examining
or stirring the fire. These pipes H also serve as stays for the roof or crown of the
gas producer. I is a charging tube traversing the upper part of the steam
generator and connecting the fuel hopper B with the interior of the gas producer A.
It is controlled by a valve J (Fig. 3) which may, as shown, be of cylindrical shape
and be formed with pockets J₁ 30 that by rotating it, fuel will be fed into the
producer in an intermittent manner and in comparatively small quantities at a
time. On the top of the steam generator are provided the usual mountings.
At the bottom of the producer, which may be water sealed as shown, is a
tuyere or air passage terminating in a conical perforated casting K containing
steam jet apparatus as usual in a gas producer.
With the arrangement described, when the fuel becomes heated in the gas
producer A, it imparts a great quantity of heat to the steam generator through the
inner wall thereof. The gas made by the producer then passes in a heated state
through the opening E into the enclosed space D' surrounding a part of the steam
generator C, round which it flows and thus assists in generating steam therein,
after which it passes through the pipe F for use in other steam generators or other
furnaces as may be required. The steam generated, passes away through a suitable
pipe L for use where required.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what
we claim is :-
1. A combined gas producer and steam generator wherein a gas producer of the
kind herein referred to having a charging opening at the top and in which gas is
made by injecting air, air and steam, or other gaseous mixture into a mass of red
hot or incandescent fuel, is constructed with double walls arranged to form the
walls of a closed steam generator that will be subjected to the heat produced
within the said gas generator and within which steam under pressure can be
produced substantially as herein described with reference to the example illustrated
in the drawings.
2. A combined gas producer and steam generator wherein a vertical gas producer
of the kind herein referred to is constructed with double walls arranged to form
the walls of a closed steam generator, and is provided with a casing arranged to
form a flue surrounding the gas producer and through which the hot producer gas

page_text: is caused to flow on its way from the producer, so that the steam generator will be
heated both internally and externally substantially as herein described.
3. A combined gas producer and steam generator constructed and arranged.
substantially as described and shown.
