PROVISIONAL SPECIFICATION.
An Improved Vertical Tubular Water Heater.
1 WILHELM HENNEBERG of Hamburg in the Empire of Germany Manufac-
turer, do hereby declare the nature of this invention to be as follows:-
This invention relates to feed water heaters and consists in an improved tubular
water heater of the following general construction.
The
A cylinder with thin sides is built into a vertical feed water heater.
cylinder surrounds the pipe system and the lower end of the cylinder is closed by
the bottom of the feed water heater the upper end being open. The direction in
which the feed water passes through the feed water heater is determined by this
cylinder. The water enters below and flows upwards between cylinder and outer
case, passes the upper edge of the cylinder and enters the cylinder, it then runs
down through the cylinder and comes out through a pipe at the bottom. The
water when rising between cylinder and outer case becomes heated by the surface
of the cylinder.
This heating suffices to separate the lighter components, such as oil, air etc.
The separation takes place at the highest point where the water runs over into
the inside of the cylinder. The water, in passing down through the cylinder, is
heated to the boiling point by means of the heating pipes.
The heavier components of the water gather in the lower part of the cylinder
and carried off by a small pipe. The passage of the water through the heater may
also be caused to take place in the direction opposite to that just described.
.
The lighter components having been separated off are taken out of the heater
through a small pipe at the top of the heater and lead by a valve to the testing
apparatus.

COMPLETE SPECIFICATION.
An Improved Vertical Tubular Water Heater.
I WILHELM HENNEBERG of 8 Königstrasse Hamburg in the Empire of
Germany, Manufacturer 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 :-
This invention relates to feed water heaters and the general object of the
improvement is to cause the lighter impurities in the water, such as oily or greasy
matters to be removed from the feed water.
Fig. in the accompanying drawings is an elevation partly in section of the
improved feed water heater, Fig. 2 being a cross section on line a Fig. 1.
The improved tubular water heater is of the following general construction.
A cylinder a with thin sides is built into a vertical feed water heater.
The cylinder surrounds the pipe system and the lower end of the cylinder is
closed by the bottom of the feed water heater, the upper end being open. The
direction in which the feed water passes through the feed water heater is
determined by this cylinder a.
The water enters below at b and flows upwards between cylinder a and outer
it then
case m, passes the upper edge c of the cylinder and enters the cylinder a,
runs down through the cylinder and comes out through a pipe d at the bottom.

page_text: The water when rising between cylinder and outer case becomes heated by the
surface of the cylinder.
This heating suffices to separate the lighter components such as oil air etc.
The separation takes place at the highest point where the water runs over into
the inside of the cylinder. The water in passing down through the cylinder is
heated to the boiling point by means of the heating pipes i.
The heavier components of the water gather in the lower part of the cylinder
and are carried off by a small pipe.
The passage of the water through the heater may also be caused to take place
in the direction opposite to that just described entering at d and leaving at b.
The lighter components having been separated off are taken out of the heater
through a small pipe fat the top of the heater and lead by a valve g. to the testing
apparatus for instance a glass chamber through the transparent walls of which the
condition of the liquid or matters passing through may be seen.
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
In a vertical feed water heater a cylinder a with thin sides, the bottom of this
cylinder being formed by the bottom of the heater, and the upper end thereof open,
whereby the feed water passes upward and downward through the heater to separate
the lighter impurities from the feed water at the highest point of the water column,
substantially as set forth.
Dated this 4th day of March 1892.
