HEATING WITH EXHAUST STEAM AND HOT WATER COMBINED
Year: 1884

page_text: I ANDERS BORCH RECK, 8 Turesensgade Copenhagen, Denmark, Civil Engineer
do hereby declare the nature of said invention for HEATING WITH EXHAUST
STEAM AND HOT WATER COMBINED, to be as follows:-
This improvement has for its object, to make heating by the exhaust steam from
a steam engine applicable, where the heat is needed at a later time than the power
of the steam engine, which produces the exhaust steam, so that the heat must be
stored up in the heating apparatus, while the engine is going.
This object is attained by employing the exhaust steam for heating of water in a
tank, well protected against cooling, and by keeping. the water from the tank in
circulation through pipes and heating coils, the said coils being incased in coil-cases
with registers for shutting off the circulation of the air in the space left between
coils and casings.
If these registers are kept shut and if the tank and coils contain water enough,
most of the heat given off by the exhaust steam, while the engine is going, can be
stored up in the water for use when the heat is needed in the buildings, where the
heating coils stand.

nature of said invention for HEATING WITH EXHAUST STEAM AND HOT WATER
COMBINED and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:
TE
This improvement has for its object to make heating by the exhaust steam from
a steam engine, applicable where the heat is needed at a later time than the power
of the steam engine, which produces the exhaust steam, so that the heat must be
stored up in the heating apparatus, while the engine is going.

This object is attained by employing the exhaust steam for heating of water in
a tank, well protected against cooling, and by keeping the water from the tank in
circulation through pipes and heating coils, the said coils being incased in coil-
cases with registers for shutting off the circulation of the air in the space left
between coils and casings. If: these registers are kept 'shut, and if the tank and
coils contain water enough, most of the heat given off by the exhaust steam, while
'the engine is going, can be stored up in the water for use, when the heat is needed
in the buildings, where the heating coils stand.

This invention is especially applicable in buildings lighted by electricity, as the
steam-engine, that drives the dynamo, generally produces more exhaust steam,
than can be employed for heating the building, during the time the electric light is
wanted. This being the case, the surplus of the exhaust steam must go to waste,
if the means, given by this invention to storing up its heat, is not resorted to..
In order that the same invention 'may be more clearly understood and carried
into effect, I will proceed, aided by the accompanying drawing, more fully to
'describe the same.

K is the steam boiler, from which high pressure steam goes to the steam-engine D
through the stop valve V. After having performed its work in the engine D,
the, steam, leaves the engine, with a low pressure, as exhaust steam, and goes
through the tube L to the coil S in the tank P. In the coil S the exhaust steam
is condensed, giving off its heat to the water in the tank. The condensed water
goes from the coil S through tube B and feed pump F to boiler K. T is a safety
valve, letting out the surplus of exhaust steam, if the engine supplies more than
required for heating the water in tank P.
The pump C keeps the water in tank P, circulating through tube G, heating
coils and back through tube J, the water giving off its heat in the coils O,
placed in the rooms, which are to be heated.
When the coils O are standing in a sufficient height over the tank P, no pump O
is needed, but the water will circulate, on account of the difference of temperature,
in the tubes G and J, just as in ordinary hot water heating apparatus.
The coils are incased in coil-cases N, with registers in top for shutting off
the circulation of the air in the space left between coils and casings. If these
registers are kept shut, and if the tank and coils contain water enough, most of
the heat, given off by the exhaust steam, while the engine is going, can be stored

coils stand.
R is a reducing valve, supplying the necessary steam direct from boiler, when
more steam is required for heating the water in tank P, that can be got from the
engine D. A, and A. are common stop valves, M is a check valve and U a blow of
cock.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I would state, that
I do not confine myself to the precise details herein described or delineated, as the
same may be varied, without altering the characteristic nature of my invention,
but what I claim, is
The combination of a steam-engine with heating of water by the exhaust steam
of the engine, the water being contained in a tank, and heating coils arranged so,
that the heat of the exhaust steam may be stored up in the said tank or the said
coils, all in the manner substantially as described and as illustrated.
