IMPROVEMENTS IN APPARATUS FOR CONDENSING EXHAUST STEAM OF STEAM ENGINES AND HEATING FEED-WATER FOR STEAM GENERATORS
Year: 1885

page_text: I, ALEXANDER MONAB, of Midtownfield, Howwood, in the County of Renfrew,
Bleacher, do hereby declare the nature of my invention for "IMPROVEMENTS IN
APPARATUS FOR CONDENSING EXHAUST STEAM OF STEAM ENGINES AND HEATING
FEED-WATER FOR STEAM GENERATORS," to be as follows:-
:-
My invention consists of an improved arrangement of condensing apparatus and
connections for effecting the condensation of the exhaust steam and producing a
vacuum in the cylinders of steam engines and at the same time heating part of the
water employed for condensing the steam so that it may be used as feed water for
steam generators.
.
In carrying out my invention I connect to the exhaust pipe of a steam engine
or engines an ordinary surface condenser of considerably smaller size than is
necessary to effect the condensation of the exhaust steam which passes through it
and to the steam space of the surface condenser I attach a pipe leading to an
Ejector Condenser or water jet condenser of the kind described in the Specification
of Morton's Patent N° 2106 of 1867, this later condenser being of a suitable size
and being supplied with sufficient water at a low temperature to effect the con-
densation of the uncondensed steam passing from the surface condenser. The cold
water which circulates through the surface condenser is heated and a portion of it
is led by a pipe to the water inlet of the Ejector Condenser or jet condenser and
may in part be used for condensing the steam entering the steam inlet of that
condenser. A separate cold water pipe is connected to the water pipe leading into
the jet condenser and is provided with a valve to regulate the admission of water
at a lower temperature so that the mean temperature of the water forming the
water jet may be low enough to effect the condensation of the uncondensed steam
from the surface condenser. A cold water pipe provided with a valve may also be
fitted to enter the usual central auxiliary steam jet inlet in the top of the jet
condenser.

page_text: To the pipe which conveys the water from the surface condenser to the jet
condenser I connect a branch to convey part of such water to a steam boiler or
range of steam boilers, and this water which is highly heated in the surface
condenser serves as feed water and may be injected into the boilers by injectors or
inspirators or in cases where a sufficient pressure of water is available it may enter
the boilers direct. I fit a valve or valves at or near the point at which this branch
is connected to the water pipe in order to direct a larger or leas quantity of water
to the feed water pipe or to the jet condenser.
I in some cases also connect the main exhaust pipe direct to the jet condenser
and fit a valve on the connecting pipe so that I may pass less or more steam
through the surface condenser and a portion direct to the jet condenser.

I, ALEXANDER MONAB, Manager of Midtownfield Bleach Works, Howwood, in
the County of Renfrew, 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 :-
My invention consists of an improved arrangement of condensing apparatus and
connections for effecting the condensation of the exhaust steam from the cylinders
of steam engines and producing a vacuum therein while at the same time heating
part of the water employed for condensing the steam so that it may be used as
feed water for steam generators or for other purposes.
In carrying out my invention I employ in conjunction with a surface condenser
which serves partially to condense the exhaust steam of an engine or number of
engines a Mortons "Ejector-Condenser" or other water jet condenser or condensers
serving to complete the condensation of the steam, the main object being to avoid
the large waste of water ordinarily resulting from the use of the ejector-condenser,
and to dispense with the employment of an air-pump in connection with the
surface condenser, from which a supply of hot water, uncontaminated by the steam,
may be obtained. The arrangement of apparatus constituting my invention is
particularly applicable in works where the bleaching, dyeing, starching and
finishing of textiles is carried on, the clean hot water from the surface-condenser
being extremely serviceable in the various operations connected with the treatment
of such goods, and also where a sufficient pressure of water is available for feeding
steam boilers without pumping or injecting apparatus.
As represented in the accompanying drawing which illustrates a modification of
the apparatus constituting my invention, the exhaust pipe A of the steam engine
or engines is connected to an ordinary surface condenser B, which is or may be of
smaller dimensions than would be required to effect the complete condensation of
the exhaust steam passing through it, and to the steam space of this surface
condenser is attached a pipe C, leading to a Mortons Ejector-Condenser, a Bulkley's
Injector-Condenser or other jet condenser D, this latter condenser being of a
suitable size and being supplied with water of a sufficiently low temperature to
effect the complete condensation of the uncondensed steam passing to it from the
surface condenser, so that a good vacuum may be produced in the cylinders of the
engines. The cold water for circulating through the tubes of the surface condenser
is supplied by a pipe E connected to one end of the casing B, and after absorbing
to a large extent the heat contained in the exhaust steam the circulation water is
led by a pipe F, connected at the opposite end of the casing B, to the water inlet d
of the jet condenser D, and may in part be used for condensing the steam entering
the steam inlet of that condenser. A separate cold water pipe G is connected
from the main supply pipe E to the pipe F leading into the jet condenser D, and is
provided with a cock or valve g to regulate the admission of cold water so that

page_text: the mean temperature of the water forming the jet may be low enough to effect
the complete condensation of the uncondensed steam passing from the surface
condenser B.
To the pipe F is connected a pipe H having a branch I to convey part, or the
whole if required, of the circulation water to a steam boiler or range of steam
boilers, and another branch J is or may be provided to conduct part of the heated
water to a reservoir or tank in the works in connection with which the apparatus
is fitted, and the water which is highly heated in circulating through the surface
condenser may in the latter case serve as wash water or for like use in treating
textiles for example, while the water passing through the branch I serves as feed-
water for the boilers, the feed being effected by injectors, inspirators or pumps in
cases where a sufficient pressure is not available for feeding the boilers direct.
A valve or cock f fitted in the pipe F between the branch H and the jet condenser,
serves to direct more or less of the hot circulation water to the jet condenser or to
the hot water supply pipe H, and cocks i and j are provided to regulate the supply
through the pipes I and J on which they are respectively fitted.
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:
:
The arrangement in combination of a surface condenser, jet condenser and pipe
connections, substantially as herein before described and for the purposes set forth.
