Improvements in Means or Apparatus for use in Filtering or Separating
the Oil from Feed Water for Steam Boilers or the like.
I, GERHARDUS HUITINK, of No. 6, Haringvliet, Rotterdam, in the Kingdom of
Holland, Mechanical Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improved means or apparatus for use in effecting the
filtration, or separation of oil from the feed water of steam boilers or the like.
The increased use of high pressure steam in boilers has correspondingly
increased the dangers arising from superheating, especially on those parts of the
boiler, where the greatest evaporation takes place.
This danger is caused principally by the oil, that from the steam cylinders
enters into the surface condensers with the exhaust steam, and through the action
of the air pump is mixed and through the feed pump enters into the steam
boiler, where it settles down on those parts where the greatest evaporation takes
place.
In order to solve the difficulty of this action of the oil I have constructed my
improved filter or means for separating the oil by utilizing the absorbent capacity
of cokes; whereby the oil is separated from the feed water and the filter.
The filter can be used month after month without expense for maintenance,
because the filter can be placed in the suction-pipe of the feed-pump; the filter
can be made of light materials, and be used with each engine.
Amongst the advantagés attendant on my improved filter or separator are that
it is always capable of being inspected and is simple in operation; its working
is not attended with expense, for the reason that the oil that is intercepted and
retained in the cokes raises the value thereof as a fuel; whilst the renewal of the
filtering material is not costly and consumes very little time to effect.
In practice the filter should be placed as low as possible so that the waste
water of the air pump shall fall regularly through the valve in the pipe of
supply into the filter.
The filter chamber may conveniently be formed of substantially rectangular
form and he divided into compartments vertically each compartment communi-
cating with its. neighbour, or neighbours, by the spaces provided by the omission
alternately at top and bottom of the vertical dividing wall.
Each compartment is provided at, some distance from the top and at a distance
from the bottom, with a reticulate roof plate and floor plate respectively and
between these two plates the comparted space is filled with packed pieces of coke.
At the head of each vertical compartment of the chamber is an outlet pipe for
air to escape.
The water, oil laden, enters from the supply and presses through the bed of
coke successively down one, up the next, and so on, until eventually it arrives
purified of oil in the final compartment which is empty and serves as a reservoir
or tank, wherein the stand of water may at any time be ascertained by means of
a water gauge provided for the purpose.
A valve and outlet pipe serve to convey the cleansed water to the feed pump.

page_text: Each compartment has an opening that communicates from the side into the space
where the coke is packed, in order to afford access for renewal and removal of
filter material. These openings are closable by caps and screwed parts.
Valves provided in openings in the floor of the compartments serve, when opened
to carry off contained matters when required, for cleaning purposes.
The top plate of the chamber may be fastened to the side parts by means of
screw bolts and rubber or asbestos packing may be used to line same.
For filling the filter top may be removed enabling access to be had at once to all
compartments.
In use the first compartment may be packed with ordinary, or coarser graded
coke; the second one with somewhat finer graded coke and the third and fourth,
and succeeding compartment (according to the number provided) may be filled
with still finer grades of coke, as may be found most convenient.
Before placing the cokes in the filter as filtering material they should be
washed and thoroughly cleansed from dirt.

Improvements in Means or Apparatus for use in Filtering or Separating

I, GERHARDUS HUITINK, of No. 6, Haringvliet, Rotterdam, in the Kingdom of
Holland, Mechanical Engineer, 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 improved means or apparatus for use in effecting the
filtration or separation of oil from the feed water of steam boilers or the like.
The increased use of high pressure steam in boilers has correspondingly
increased the dangers arising from superheating, especially on those parts of the

DESCRIPTION OF THE DRAWINGS.
Fig. 1 shows a vertical longitudinal section of the improved filtering

page_text: In practice the filter should be placed as low as possible so that the waste
water of the air pump shall fall regularly through the valve A in the pipe of
supply into the filter.
The filter chamber may conveniently be formed of substantially rectangular
form and be divided into compartments C, D, E, F and H vertically each com-
partment communicating with its neighbour, or neighbours, by the spaces pro-
vided by the omission alternately at top and bottom of the vertical dividing wall.
Each compartment is provided at some distance from the top and at a distance
from the bottom, with a reticulate roof plate and floor plate respectively and
between these two plates the comparted space is filled with packed pieces of coke.
(Although in the drawing Fig. 1 portions of the masses of coke have been omitted
for sake of clearness).
At the head of each vertical compartment of the chamber is an outlet pipe G
for air to escape.
The water, oil laden, enters from the supply and presses through the bed of
coke successively down one, up the next, and so on, until eventually it arrives
purified of oil in the final compartment H which is empty and serves as a reser-
voir or tank, wherein the stand of water may at any time be ascertained by
means of a water gauge K provided for the purpose.
A valve B and outlet pipe serve to convey the cleansed water to the feed pump.
Each compartment has an opening that communicates from the side into the
space where the coke is packed, in order to afford access for renewal and removal
of filter material. These openings are closable by caps and screwed parts J.
Valves I provided in openings in the floor of the compartments serve, when
opened to carry off contained matters when required, for cleaning purposes.
The top plate L of the chamber may be fastened to the side parts by means of
screw bolts and rubber or asbestos packing may be used to line same.
For filling the filter top may be removed enabling access to be had at once to
all compartments.
In use the first compartment may be packed with ordinary, or coarser graded
coke, the second one with somewhat finer graded coke and the third and fourth,
and succeeding compartment (according to the number provided) may be filled
with still finer grades of coke, as may be found most convenient.
Before placing the cokes in the filter as filtering material they should be
washed and thoroughly cleansed from dirt.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. The construction or arrangement and combination of parts of apparatus for
utilizing the absorbent capacity of coke for filtering or separating oil from, the
feed water of steam boilers, or the like, substantially as described and shown by
the accompanying drawings.
2. The construction and use of the filtering or separating means or apparatus for
separating oil from feed water of steam boilers, and the like so as to facilitate
inspection, renewal of the filtering material and utilization of the filtering material
with its compliment of oil as fuel, as set forth.
