PROVISIONAL SPECIFICATION.
Improved Apparatus for Generating and Consuming Combustible
Gas.
I GEORGE LOVE, Malton House, Quebec, County of Durham, Engineer, do hereby
declare the nature of this invention to be as follows:-
-
To carry my invention into effect I form a suitable furnace or stove having hollow
perforated bars or pipes such bars or pipes may be at the bottom or otherwise of the
fuel, as may suit the particular position and purpose of the furnace or stove.
Through these perforated bars or pipes I force air, by means of an air pump or other
suitable apparatus, for the purpose of causing the fuel acted upon by such air, to
become incandescent. I have a suitable valve or valves toj regulate the quantity of
air admitted through such bars or pipes to the fuel; through another series of hollow
perforated pipes or bars, I admit steam or vapour, to the incandescent fuel, having
a suitable valve or valves, to regulate the quantity of steam or vapour so admitted to
the incandescent fuel, and that the supply of air and vapour may be so regulated, as
to insure the decomposition of the vapour, and reduction of the fuel. At the outlet of
such generating apparatus, I form an air chamber or chambers, to which I admit air,
and by means of perforations I mix this air with the combustible gas generated, in
such apparatus, for the purpose of combustion.

COMPLETE SPECIFICATION.
Improved Apparatus for Generating and Consuming Combustible
Gas.
I, GEORGE LOVE, of Malton House, Quebec, in the County of Durbam, 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:-
This invention has for its object to produce improved apparatus for effecting more
complete combustion of the fuel than hitherto, and also for effecting the combustion
of the gases generated from the fuel thus enabling small coal, slack or coal dust,
coke ballast or breeze to be burnt with as good results as are produced by burning
large steam coal in the ordinary furnaces or apparatus.
And in order that my invention may be well understood and carried into
practice I will now proceed to describe the same with reference to the accompanying
drawings in which the application of my invention to a single flued boiler is
illustrated. Similar letters of reference indicate corresponding parts in all the
figures.
Figure 1 is a front elevation; Figure 2 is a section on the line A A Figure 1;
Figure 3 is a section on the line B B and Figure 4 is a section on CC Figure 2.
In carrying my invention into practical effect I provide the stove or furnace with
an open hearth F on to which a forced draught is caused to impinge through
perforated bars or pipes H arranged across the front of the hearth as shewn in the
drawings, along the bottom or sides or in any other convenient position for quickly
rendering the fuel incandescent. I also provide a second series of perforated bars or
pipes J into which I admit steam or vapour which, by the perforations, is directed on
to the incandescent fuel and there becomes thoroughly decomposed and at the same
time effects the complete reduction of the fuel. At the rear of the hearth I provide
one or more air chambers M. Into these air chambers independent pipes or air

page_text: passages C convey air which escapes from the said chambers through perforations D
therein, and mingles with the gases generated on the hearth and causes the com-
bustible gases to burn.
In the drawings I have shewn the steam pipes or bars J alternating with the air
pipes or bars H, but I do not confine myself to this arrangement as it is obvious that
they may be placed in any other position where the steam or vapour issuing through
the perforations may impinge upon the incandescent fuel and effect the desired
result. The tube A is connected with an air pump, fan, or similar means for forcing
air, and supplies air to the perforated pipes or bars H; and the tube B supplies steam
or vapour to the perforated pipes or bars J. Both A and B are fitted with regulating
cocks or valves L, as also are the pipes C which supply the air to the air chambers M.
N is an ordinary screen or furnace door.
The action of the apparatus as follows: The fuel is charged into the hearth F
through a suitable hopper or door E. A fire is built on the hearth and forced air
is then admitted to the perforated pipes or hars H through the tube A. When the
fuel is sufficiently incandescent, steam or vapour is admitted to the pipes or
bars J through the tube B, and air to the air chamber or chambers M by means
of the pipes C.
I wish it to be clearly understood that I do not confine myself to the
arrangement of apparatus or the details as herein shewn and described, as
these may be considerably modified without departing from the essence 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 1 declare that what I
claim is :-
(1) In combination with an open hearth furnace, the perforated air and steam
pipes or bars H and J and the perforated air chambers M supplied with air by the
independent air pipes or passages C, substantially as and for the purpose hereinbefore
described and illustrated in the accompanying drawings.
(2) My improved apparatus for economizing fuel and for generating and con-
suming combustible gases substantially as described and illustrated.
