Improvements in and Connected with Reverberatory Furnaces

Operations.
I, JOHN SPENCER of Phoenix Iron Works, Coatbridge, in the County of Lanark,
North Britain, Ironmaster, do hereby declare the nature of this Invention to. be. as
follows, that is to say :-
My said Invention has for its object by an improved and simplified construction of
reverberatory furnaces and parts connected therewith, to obtain increased efficiency
with economy of fuel and reduced cost of primary construction and repairs.
In carrying out my Invention I construct at one end of the reverberatory chamber
a gas-producer furnace of any simple and convenient kind having at its upper part
ports through which the gas enters the reverberatory chamber. Above the gas inlet
ports there are air inlet ports through which heated air enters the reverberatory
chamber to supply what is required for the combustion of the gas. The air is led to
the air inlet ports through vertical flues in the wall dividing the gas-producer furnace
from the reverberatory chamber, and it reaches these vertical flues through horizontal
flues formed under the reverberatory chamber. From the other end of the rever-
beratory chamber the used fire gases pass by one or more ports or passages into
chimney, the lower part of which is divided by thin firebrick partitions into. a number
of vertical passages or flues. These flues are connected at their lower and upper ends
in such manner that the used fire gases pass up through the alternate. flues, whilst the
air supplied to the furnace, and which is by preference propelled by a fan or blower
passes through the remaining flues and becomes highly heated by the beat remaining
in the fire gases. The air may be led first to the upper ends of all the air-heating
flues, or it may be led first into the lower ends of some of the flues so as to pass up
them and return down others; and the air thence proceeds through the flues under
the reverberatory chamber to the vertical flues and inlet ports at the inlet end. When
the chimney has to be placed at a little distance from the reverberatory chamber the
air-heating flues may be constructed partly or entirely in the horizontal passage
between the reverberatory chamber and chimney; but in all cases the air-heating
flues are made parallel to the flues through which the used fire gases pass.

Improvements in and Connected with Reverberatory Furnaces
for Heating, Metallurgical, Glass-making, and other similar
Operations.
I, JOHN SPENCER, of 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 by an improved and simplified construction of
reverberatory furnaces and parts connected therewith, to obtain increased efficiency
with economy of fuel and reduced cost of primary construction and repairs.
In carrying out my Invention I construct at one end of the reverberatory chamber a
gas-producer furnace of any simple and convenient kind having at its upper part one
or more ports through which the gas enters the reverberatory chamber. Above or in
the top of the gas inlet port or ports there are air inlet ports through which air enters
the reverberatory chamber to supply what is required for the combustion of the gas.
From the other end of the reverberatory chamber the used fire gases pass by one or
more ports or passages into a chimney, the lower part of which is divided by thin
firebrick partitions into a number of vertical passages or flues. These flues are con-
nected at their lower and upper ends in such manner that the used fire gases pass up
through some of the flues, whilst the air supplied to the furnace, and which is by
preference propelled by a fan or blower passes through flues between the fire-gas flues
and becomes highly heated by the heat remaining in the fire gases. After passing
through the flues in the chimney the air proceeds under the reverberatory chamber to
vertical flues communicating with the air inlet ports leading into the reverberatory
chamber.
When the chimney has to be placed at a little distance from the reverberatory
chamber the air-heating flues may be constructed partly or entirely in the horizontal
passage between the reverberatory chamber and chimney; but in all cases the air
heating flues are made parallel to the flues through which the used fire gases pass.
On an accompanying sheet of explanatory drawings, a reverberatory furnace and
parts connected therewith are shown as constructed according to my Invention,
figure, 1, being a horizontal section, figure, 2, a transverse vertical section as at the
lines A A, in figures, 1, and 3, and figure, 3, a longitudinal vertical section. In
these drawings the same reference letters are used to mark the same or like parts
wherever they are repeated.
The reverberatory chamber, B, which is of an ordinary construction and which may
be of any known construction suitable for the operation to be effected in the apparatus,
has at one end of it a fuel chamber, C, shown as constructed like that of an ordinary
puddling or heating furnace, but which is worked as a gas-producer with a limited air
supply. The gas formed in the chamber, C, passes through a port, D, the same as the

page_text: ordinary passage over a fire bridge, E, into the reverberatory chamber, B. The used
fire gases pass from the reverberatory chamber, B, through ports, F, into two vertical
flues, G, formed in the lower part of a chimney, H. Between the vertical fire-gas
flues, G, there are formed with thin firebrick two vertical air-heating passages, J, K,
connected by a port at the top and air from a fan or blower is led by a pipe, L, into
the bottom of one flue, J; and the air passing up this flue returns down the other
one, K, and proceeds into a chamber, M. From the chamber, M, the air passes
through one or more iron pipes, N, under the reverberatory chamber, B, into a
chamber, P, in the lower part of the bridge, E, and thence proceeds by vertical
flues, Q, formed in the side walls, up into a transverse flue, R, formed over the
passage or port, D, at the top of the bridge, E. A number of ports, S, are formed
from the flue, R, into the passage, D, and the air issuing from these ports, and
which has become considerably heated in passing through the various flues and pipes,
mingles and combines with the gas passing into the reverberatory chamber, B, causing
intense combustion and great heat.
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 :-
Constructing reverberatory furnaces and parts connected therewith with air-heating
flues combined with and parallel to flues through which the used fire gases pass, and
otherwise substantially in the improved manner hereinbefore described.
