A Construction of Steam Generating Apparatus in Combination with
Smelting and other Heating Furnaces.
I, ADOLF PFOSER, of Achern, Baden, Germany, Engineer, do hereby declare the
nature of this invention to be as follows:-
The present invention relates to a construction of steam generating apparatus
in combination with smelting and other heating furnaces which enables the heat
of the latter which is otherwise lost by radiation and conduction to be utilised
for the production of steam.
For this purpose, tubes serving as steam generators are imbedded in the brick-
work of the furnace, not only in the roof thereof, for utilising the heat that is
otherwise lost by radiation, but also in the hearth of the furnace for taking up
the heat that in being conducted downward through the brickwork, is otherwise
lost.
I will describe my said invention with reference to the accompanying drawing
in which it is shewn by way of example applied to a glass melting furnace.
Fig. 1 shews a cross section of the furnace on line 1-1 Fig. 3; Fig. 2 a front
view of the same; Fig. 3 a horizontal section on line 3-3 Fig. 1; and Fig. 4
a longitudinal section on line 4-4 Fig. 1.

a is a feed pipe with check valve b, Figs. 2 and 4, through which the water
passes into the horizontal pipe c and thence into a series of pipes c¹. On the
latter are fixed vertical pipes d the upper ends of which are connected together
by pipes e leading to the collecting pipes f f¹.
By means of the heat which penetrates through the hearth of the furnace, the
feed water circulating through the above mentioned set of pipes is heated and
it then passes through the pipes g g and h h¹ Fig. 1, into the steam
generator. From rise vertical pipes which at their upper ends are con-
nected together by pipes which communicate with the collecting pipes A A¹
arranged at the front and back and over the roof of the furnace, and which are
again connected together by a grid of pipes m Fig. 3. The steam generated
in the system of pipes, in flowing through the pipes in the neighbourhood of the
crown of the arch, becomes superheated and passes into a central collector S from
which it can be taken off through the valve V to the place of consumption.
By means of the pipes o o¹ any water carried along by the steam can flow back
into the water pipes.
s
By means of a second feed pipe q with check valve b¹, a supply of water also
flows into a second system of pipes, formed by the collecting pipes B B which
are connected together by pipes r and constitute a feed water heater. From
this system of pipes the water flows through the pipes to the steam generating
pipes. These are connected to the collecting pipe C Fig. 2 and consist of pipes U
and t of a less diameter which are situated in channels formed in the hearth of
the furnace. These pipes U and are connected to the chambers 12 situated in
the back part of the furnace, a pipe U passing from the collector C parallel with

page_text: the furnace axis being made to conduct the water into this closed chamber B2,
from which it passes back through pipes t to the front again and into the
collectors B³ and B. 13 and B* again are connected to a collector common to both.
By the pipe W the steam generated in this system is led into the main collecting
pipe S. The pipes X serve for leading back any water that may be carried along
by the steam.
By means of suitable closing devices in the tubes U the system of pipes
enclosed in the channels of the furnace hearth can be put in or out of action
as may be required.

A Construction of Steam Generating Apparatus in Combination with
Smelting and other Heating Furnaces.
I, ADOLF PFOSER, of Achern, Baden, Germany, 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 present invention relates to a construction of steam generating apparatus
in combination with smelting and other heating furnaces which enables the heat
of the latter which is otherwise lost by radiation and conduction to be utilised
for the production of steam.
For this purpose, tubes serving as steam generators are imbedded in the brick-
work of the furnace, not only in the roof thereof, for utilising the heat that is
otherwise lost by radiation, but also in the hearth of the furnace for taking up
the heat that in being conducted downward through the brickwork, is otherwise
lost.
I will describe my said invention with reference to the drawing accompanying
my Provisional Specification in which it is shewn by way of example applied to
a glass melting furnace.
Fig. 1 shews a cross section of the furnace on line 1-1 Fig. 3; Fig. 2 a front
view of the same; Fig. 3 a horizontal section on line 3-3 Fig. 1; and Fig. 4
a longitudinal section on line 4-4 Fig. 1.
a is a feed pipe with check valve b, Figs. 2 and 4, through which the water
passes into the horizontal pipe cand thence into a series of pipes c¹. On the
latter are fixed vertical pipes d the upper ends of which are connected together
by pipes e leading to the collecting pipes ff.
By means of the heat which penetrates through the hearth of the furnace, the
feed water circulating through the above mentioned set of pipes is heated and
it then passes through the pipes g g¹ and h h¹ Figs. 1, 2 and 3, into the steam
generator. From h¹ rise vertical pipes i i¹ which at their upper ends are con-
nected together by pipes which communicate with the collecting pipes A A¹
arranged at the front and back and over the roof of the furnace, and which are
again connected together by a grid of pipes m Figs. 1, 3 and 4. The steam generated
in the system of pipes, in flowing through the pipes in the neighbourhood of the
crown of the arch, becomes superheated and passes into a central collector S from
which it can be taken off through the valves V to the place of consumption.
By means of the pipes o o¹ any water carried along by the steam can flow back
into the water pipes.
By means of a second feed pipe 2 with check valve 1, a supply of water also

page_text: flows into a second system of pipes, formed by the collecting pipes B B which
are connected together by pipes r and constitute a feed water heater. From
this system of pipes the water flows through the pipes to the steam generating
pipes. These are connected to the collecting pipe C Fig. 2 and consist of pipes U
and t of a less diameter which are situated in channels formed in the hearth of
the furnace. These pipes U and t are connected to the chambers B situated in
the back part of the furnace, a pipe C passing from the collector C parallel with
the furnace axis being made to conduct the water into this closed chamber B²,
from which it passes back through pipes to the front again and into the
collectors B3 and B. B³ and B again are connected to a collector 15 common
to both.
By the pipe W the steam generated in this system is led into the main collecting
pipe S. The pipes X serve for leading back any water that may be carried along
by the steam.
By means of suitable closing devices in the tubes U the system of pipes
enclosed in the channels of the furnace hearth can be put in or out of action
as may be required.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. A construction of steam generating apparatus in combination with smelting
and other furnaces, consisting of sets of pipes built into the sides and roof of the
furnace, which receive the feed water from feed water heaters such as d and from
which the the steam generated is led through pipes A A¹ into a steam collecting
chamber S, from which the steam is supplied to the places of consumption, sub-
stantially as described.
2. A construction of steam generating apparatus in combination with smelting
and other furnaces consisting of sets of pipes U contained in channels formed in
the bed of the furnace and combined with feed water heaters and collectors, in
such manner that each group of pipes in one of the said channels receives feed
water from the feed water heater B B while the steam produced therein by the
heat conducted down through the bed of the furnace is led through pipes B³ B+ B³
and W to the common steam collecting chamber s substantially as described.
3. Steam generating apparatus for utilising the waste heat given off from
smelting and other furnaces by radiation and conduction, combined and operating
as herein described with reference to the drawings.
