I, JOHN IMRAY, of N° 28 Southampton Buildings, Chancery Lane in the County
of Middlesex, Consulting Engineer and Patent Agent, do hereby declare the nature
of my invention for "A METHOD OF GENERATING STEAM, CONDENSING WASTE STEAM
AND FEEDING THE GENERATOR to be as follows:-
"
This invention relates to a method of generating steam, condensing waste steam
and feeding the generator with the products of condensation, and has for its main
object economy of fuel.
For this purpose a boiler or steam generator is supplied with a more or less
concentrated solution of carbonate of soda, nitrate of ammonia or other salts, the
solutions of which have high boiling points.
The steam generated from such liquid may be applied for driving engines direct,
or for producing steam from solutions of lower boiling point or from water.
The feeding of the generator is wholly or partly effected by returning the water
resulting from condensation of waste steam to the generator, the condensation
being effected as follows:
:
From the generator a portion of its contents is caused to flow continuously or
intermittently into a reservoir or tank becoming cooled on its way below its boiling
point in passing by pipes, or other channels, through one or more boilers containing
liquids having boiling points below that of the liquid in the generator, heating
these and generating steam from them.
The waste steam is led into the reservoir and condensed by the liquid of the
generator cooled as above described; and from the reservoir liquid is returned to
the generator by an injector or by a force-pump, the working of which may be
aided by the pressure of the cooled liquid which is that of the generator.

J, JOHN IMRAY of N° 28 Southampton Buildings, Chancery Lane in the County
of Middlesex, Consulting Engineer and Patent Agent do hereby declare the nature
of my 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 relates to a method of generating steam, condensing waste steam
and feeding the generator with the products of condensation, and has for its main
object economy of fuel.
For this purpose a boiler or steam generator is supplied with a more or less
concentrated solution of carbonate of soda, nitrate of ammonia or other salts or
substances the solutions of which have high boiling points.
The steam generated from such liquid may be applied for driving engines direct,
or for producing steam from solutions of lower boiling point or from water.
The feeding of the generator is wholly or partly effected by returning the water
resulting from condensation of waste steam to the generator, the condensation
being effected as follows.
From the generator a portion of its contents is caused to flow continuously or
intermittently into a reservoir or tank, becoming cooled on its way below its
boiling point in passing by pipes, or other channels, through one or more boilers
containing liquids having boiling points below that of the liquid in the generator,
heating these and generating steam from them.
The waste steam is led into the reservoir and condensed by the liquid of the
generator cooled as above described; and from the reservoir liquid is returned to
the generator by an injector or by a force-pump the working of which may be
aided by the pressure of the cooled liquid, which is that of the generator.
Instead of arranging the steam generator containing the liquid of a lower boiling
point separate from that containing the liquid of high boiling point, these may be
arranged as separate compartments of one and the same boiler, and there may be
two or more such compartments containing liquids of lower boiling points than
that of the above mentioned solution, so arranged, that this solution is led through
pipes passing first through a compartment containing liquid having a boiling point
lower than that of the solution, then through a second compartment containing
liquid having a boiling point lower than that of the liquid in the preceding com-
partments, and so on, the cooled solution being eventually conducted into the
before mentioned tank in which it effects the condensation of the waste steam.
The said other compartments may either be entirely heated by the concentrated
solution for the generation of steam or partly by this and partly by independent
fire heat.
Solutions of glycerine and water may also be employed for the purpose of this
invention, as with these boiling points of 400° Fahr. and higher may readily be
obtained.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The herein described method of generating steam wherein the generator is fed
with artificial solutions or liquids having a high boiling point, the waste steam,
after condensation being fed back into the boiler so as to maintain one and the
samme body of solution or liquid in continuous action.
2. In generating steam according to the method referred to in the preceding
claim, arranging the steam generator with two or more separate compartments or
vessels, each containing a solution or liquid having a boiling point different from.
that of the other or others, the solution having the highest boiling point being in
part led through pipes or passages in the compartments or vessels having solutions
or liquids of lower boiling point so as to impart its heat to these, in order when
cooled to serve as means for condensing the exhaust steam of the motor engine
worked by the generator, substantially as herein described.
3. In generating steam as set forth in the first claim, the method of effecting
the cooling of a portion of the solution of high boiling point in order to enable it
to condense the exhaust steam of a motor engine by causing such solution to
pass from its generator through two or more compartments or separate vessels
or generators containing liquid of a lower boiling point, substantially as herein
described.
