Heater, Economiser, and Separator.
I, WILLIAM DEIGHTON, of One Ash, Hall Lane, Chapeltown Road, Leeds, in the
County of Yorkshire, Engineer, do hereby declare the nature of this invention to
be as follows:-
My improvement relates to a combination jet and surface condenser, feed water
heater, economiser, and separator, and is constructed in the following manner:
The outer shell or casing I prefer to make in a circular form, of metal plates of
any desired height and diameter, the said casing or shell being divided into three parts
or chambers, (by horizontal plates) which may vary in depth as required. The
upper part or chamber is further divided by a central vertical tube of suitable
diameter, forming a water jet or spray chamber, communicating with and open
to the middle chamber.
The upper chamber acts as the steam receiving chamber. The middle chamber
is the hot well, and contains the surface condensing tubes, the said tubes being
secured to the two horizontal plates dividing the upper and lower chambers from
the middle chamber.
The lower chamber receives the uncondensed steam from the tubes, and acts as
a separator and oil or grease receiver.
To the lower or separating chamber a pipe, or pipes, is, or are arranged, to
carry any uncondensed steam to the cold water spray or jet chamber. The cold
water spray or jet is regulated by a suitable valve, and the water supply is con-
trolled by an automatic valve connected by rods & levers to a float, working in
the upper portion of a tube, or pipe secured in a vertical position inside the middle
chamber, or hot well.
A smaller pipe is connected with the bottom of the before mentioned tube, and
passing through the outer casing forms the outlet for the purified feed water.
Provision is made for taking off the separated oil, grease, and like substances
from the bottom chamber, and also for carrying away the lime, and other deposits
from the middle chamber.
The method of working is as follows:-The exhaust steam enters the upper
chamber surrounding and heating the inner water spray or jet chamber; the
steam then passes down the condensing or heating tubes of middle chamber, on its
way to the lower or separating chamber. In this chamber the oil, grease, and
similar substances, are separated from the uncondensed steam. The uncondensed
steam then passes up through the pipe, or pipes, into the cold water spray or jet
chamber, where it comes in contact with the cold water spray or jet, the con-
densed steam and water falling into the middle chamber or hot well, to be with-
drawn in a state of high temperature for use.
Any uncondensed steam, and excess of water passes away through the overflow,
and outlet steam connections.

I, WILLIAM DEIGHTON, of One Ash, Hall Lane, New Leeds, Leeds, in the
County of York, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My improvement relates to a combination jet and surface condenser, feed water
heater, economiser and separator, and is constructed in the following manner :-
The outer shell or casing I prefer to make in a circular form of metal plates of
any desired height and diameter, the said casing or shell being divided into three parts
or chambers, (by horizontal plates) which may vary in depth as required. The
upper part or chamber is further divided, by a central vertical tube of suitable
diameter, forming a water jet or spray chamber, communicating with and open
to the middle chamber.
The upper chamber acts as the steam receiving chamber. The middle chamber
is the hot well, and contains the surface condensing tubes, the said tubes being
secured to the two horizontal plates dividing the upper and lower chambers from
the middle chamber.
The lower chamber receives the uncondensed steam from the tubes and acts as
a separator and oil or grease receiver.
To the lower or separating chamber a pipe, or pipes, is, or are, arranged to
carry any uncondensed steam to the cold water spray or jet chamber.
The cold water spray or jet is regulated by a suitable valve, and the water supply
is controlled by an automatic valve connected by rods and levers to a float, working
in the upper portion of a tube, or pipe, secured in a vertical position inside the
middle chamber or hot well.
A smaller pipe is connected with the bottom of the before mentioned tube, and
passing through the outer casing forms the outlet for the purified feed water.
Provision is made for taking off the separated oil, grease and like substances
from the bottom chamber, and also for carrying away the lime and other deposits
from the middle chamber..
The method of working is as follows:-The exhaust steam enters the upper
chamber, surrounding and heating the inner water spray or jet chamber; the
steam then passes down the condensing or heating tubes of middle chamber on its
way to the lower, or separator chamber. In this chamber the oil, grease, and

similar substances, are separated from the uncondensed steam.
steam then passes up through the pipe, or pipes, into the cold water spray or jet
chamber, where it comes in contact with the cold water spray or jet, the con-
densed steam and water falling into the middle chamber or hot well, to be with-
drawn in a state of high temperature for use.
Any uncondensed steam, and excess of water passing away through the overflow,
and outlet steam connections.
In the accompanying sheet of drawings Fig. 1. is a sectional elevation, and
Fig. 2, is a sectional plan on the line a, a, Fig. 1.
a, is the outer shell or casing, which is divided horizontally by the plates f
ff, into an upper chamber b, central or middle chamber c, and lower chamber d.
The exhaust steam enters the upper chamber b from the pipe 7, and surrounds
and heats the inner water spray or jet chamber h.
It then passes down the vertical tubes e, e, e, and is discharged into the lower
chamber d.

page_text: In this chamber the oil, grease and similar substances are separated from the un-
condensed steam.
The uncondensed steam is afterwards conducted up through the pipe y, to the
cold water spray or jet chamber h, where it meets the cold water spray or jet j
and is condensed, falling with the water into the middle chamber or hot well c.
From this chamber c it is drawn off in a state of high temperature through the
pipe o as required for use.
Any uncondensed steam passes out through the pipe 7, and the over flow water
is carried away by q.
The floats, and rods n, connected to the valve m, automatically regulate the
water supply to the water spray or jet chamber h, and the valve controls the jet j.
A pipe t, and cock t', is provided for emptying and drawing off any sediment
from the centre chamber or hot well e as required, and a cock is also provided
for drawing off the oil, and grease from the chamber d.
I do not confine myself to the exact construction of parts shown, which may be
varied to suit requirements without departing from my invention.
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. In a combined jet and surface condenser, feed water heater, economiser, and
separator the combination and arrangement of separate chambers one above the
other, and a series of vertical tubes passing through the middle chamber with a
jet or spray chamber open to and communicating with the middle chamber, as
described and illustrated by the accompanying drawings.
2. In a combined jet and surface condenser, feed water heater, economiser, and
separator the combination and arrangement of separate chambers one above the
other, and a series of vertical tubes passing through the middle chamber, with
an automatic valve connected to a float working in a tube in the middle chamber,
as described and illustrated by the accompanying drawings.
3. The general arrangement and construction of a combined jet and surfaco
condenser, feed water heater, economiser, and separator, as described and illus-
trated by the accompanying drawings.
