PROVISIONAL SPECIFICATION
Improvements applicable to Reverberatory Furnaces Used for
Metallurgical Purposes
I, JOHN SPENCER of the Phoenix Iron Works, Coatbridge, in the County of
Lanark, North Butan, Ironmaster, do hereby declare the nature of this invention
to be as follows, that is to say
-
fuel
My sud invention has for its object the heating of reverberatory furnaces in an
improved and economical manner, and so that the heated gases acting in such
furnaces may be of suitable quality for the various operations conducted therein
In carrying out my invention according to one modification I construct
chamber on fire place at one end of a building in which the reverberatory furnace
is consti ucted, the communication between the fuel chamber and reverberatory
chamber being below a hanging bridge which may be made movable so that its
height may be adjusted for different requirements The coal is filled into the
fuel chamber nearly up to the bottom of the hanging bridge or higher, and
all or put of the air for combustion is introduced under pressure into a box
crossing the outer end of the fuel chamber and placed a little lower than the
hanging bridge and opposite to it The box is perforated and the an unde
pressure from it proceeds through the fuel in a horizontal or somewhat inclined
dnection towards the communication with the reverberatory chamber In addition
to the air entering below the top of the fuel there may be an air inlet with a
regulating damper or valve above the fuel and there may be an inlet with
a regulating damper o valve above the communication with the reverberatory
chamber the air being directed downwards amongst the fuel gases passing through
so as to complete the combustion of those gases when such action is desirable for
the operation which is being conducted in the reverberatory chamber
The air
supplied as herein before described is by preference heated by means of the used
gases passing off from the reverberatory chamber or in any other convenient way

Improvements applicable to Reverberatory Furnaces Used for
Metallurgical Purposes
I, JOHN SPENCER, of the Phoenix Iron Works, Coatbridge, in the County of
Lanark, North Britain, Ironmaster, 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, that is to say
-
My said invention has for its object the heating of reverberatory furnaces in an
improved and economical manner, and so that the heated gases acting in such
furnaces may be of suitable quality for the various operations conducted therein
In carrying out my invention I construct a fuel chamber or fire place in the

page_text: same building with the reverberatory furnace, the communication between them being
below a hanging bridge to the bottom of which the coal in the fuel chamber is filled
Air for combustion is introduced under pressure into a perforated box at the lower
part of the fuel chamber Air may be also introduced above the fuel, and into the
communication between the chambers the air being by preference heated by the
waste gases of the reverberatory furnace or otherwise
And in order that my said invention and the manner of performing the same may
bc properly understood I hereunto append sheet of explanatory drawings, to be
be reinafter referred to, and showing a reverberatory furnace and parts appertaining
thereto as made according to my invention
Figure, 1, of the drawing is an end elevation
Figure 2, is a side elevation
Figure, 3, is a horizontal section taken generally as at the dotted line M-M, and
partly at the sides as through the dotted line N-N in Figure, 4
Figure, 4, is a longitudinal vertical section
In these drawings the same reference letters are used to mark the same or like
parts wherever they are repeated
In carrying out my invention I construct a fuel chamber or fire place A, at one
end of a building in which the reverberatory furnace, B, is constructed, the com-
munication between the fuel chamber and reverberatory chamber being below
a hanging bide, C which is fixed but may be made movable so that its height
may be adju ted for different requirements
The coal is filled into the fuel
chamber, A, nearly up to the bottom of the hanging bridge, C, or highet ind all
01 part of the au foi combustion is introduced under pressure by a pipe I, into
a box, D, crossing the outer end of the fuel chamber, A, and placed a little lewer
than the hanging bridge, C, and opposite to it The box, D, is perforated, and the
air under pressure from it proceeds through the fuel in a horizontal or somewhat
inclined direction towards the communication, E, with the reverberatory chamber, B
Air finding its way to the space above the fuel in the chamber, A, can pass thence
to the reverberatory chamber, B, by a passage or passages, K In addition to
the an entering below the top of the fuel there may be an an inlet with a regulating
damper or valve above the fuel if desued and there are a series of air inlets, G,
extending tian veisely which may be provided with regulating dampers or valves
(not shown) above the communication, E, with the reverberatory chamber, B, the
air entering by the passage, H, and being directed downwards amongst the fuel
gases passing through so as to complete the combustion of those gases when such
action is desirable for the operation which is being conducted in the reverberatory
chamber, B I he air supplied as herein before described is by preference heated
by means of the used gases passing off from the reverberatory chamber or in
any other convenient way Brick chequer work, J, 1s arranged in the com-
munication, E, between the fuel chamber, A, and the reverberatory furnace, B
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
-
The combination and arrangement of parts constituting the improved reverberatory
furnace for metallurgical purposes substantially as hereinbefore described
