Our invention relates firstly to the apparatus known as "fuel economisers" used
for the purpose of heating water or generating steam by means of the heat of the
waste heated gases from steam boilers or other furnaces and our invention relates
more particularly to those parts of such fuel economisers aforesaid which are
commonly designated." bottom boxes" which bottom boxes receive the impurities
separated from the water while being heated in the fuel economisers before
mentioned-Our invention consists firstly in forming the bottom of each of such
bottom boxes inclined toward the "blow off" or "mud" pipe usually employed in
conjunction with fuel economisers by which blow off" or "mud" pipe the
impurities separated from the water heated in the fuel economiser may be removed
by means of a "blow off" tap or cock in the ordinary manner-We form each of
the bottom boxes aforesaid so that the lowest part of the bottom of the said bottom
box shall be under those pipes of each section of the fuel economiser which are
farthest from the feed water inlet of each section of such fuel economiser, and by
so doing we prevent the pipes aforesaid from becoming as readily as heretofore
filled with and choked by the impurities separated from the water.

We ARTHUR LOWCOCK of The Economiser Works Shrewsbury in the County of
Shropshire Engineer and THOMAS SYKES of 25 Milton Street Stockport Road
Manchester in the County of Lancaster Engineer do hereby declare the nature
of our invention for IMPROVEMENTS IN THE APPARATUS KNOWN AS
ECONOMISERS AND USED FOR HEATING WATER AND GENERATING STEAM WHICH
IMPROVEMENTS ARE ALSO APPLICABLE TO OTHER APPARATUS SIMILAR IN CON-
STRUCTION TO THE APPARATUS KNOWN AS "FUEL ECONOMISERS AND USED FOR
HEATING AND PURIFYING WATER and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
"
"
The first part of our invention relates to the apparatus known as fuel economisers
used for the purpose of heating water or generating steam by means of the heat of
the waste heated gases from steam boilers or other furnaces and this part of our
invention relates more particularly to those parts of such fuel economisers aforesaid
which are commonly designated "bottom boxes" which "bottom boxes receive
the impurities separated from the water while being heated in the fuel economisers.
above mentioned and this first part of our invention consists in improved arrange-
ments of apparatus by the employment of which improved arrangements of
apparatus we binder or prevent the pipes of such fuel economisers from becoming
filled with and choked by the impurities separated from the water while being
heated in the said fuel economisers and enable the said impurities to be removed
from the pipes and bottom boxes of such fuel economisers more readily and with
greater certainty than has hitherto been possible.
In order that our invention may be fully understood and readily carried into
effect we will now proceed to describe the same by reference to the drawing.
hereunto annexed in which drawing Fig. 1 is a vertical cross section Fig. 2 is a
vertical cross section through the line XY at right angles to Fig. 1 and Fig. 3 is
a plan of so much of a fuel economiser as is requisite to illustrate the first part of
our invention Similar letters of reference are applied to corresponding parts in all
the said Figs. 1. 2 and 3. a b are the walls between which the vertical pipes c of
the fuel economiser are situate-The vertical pipes c communicate at their upper
ends with the top boxes d of which top boxes à one only is shown in Fig. 1 while
two are shown in Fig. 2 and at their lower ends the vertical pipes c communicate
with the bottom boxes e of which bottom boxes e one only is shown in Fig. 1.
while two are shown in the cross section Fig. 2 and in the plan Fig. 3. The
vertical pipes c are connected in any suitable and convenient manner to the top

page_text: boxes d and bottom boxes e-We form the bottom e¹ of each of the bottom boxes e
so that such bottom e¹ slopes or is inclined towards and leads to the blow off or
nud pipe f which blow off or mud pipe f communicates with the blow off or mud
pipe g.
The water to be heated while circulating or passing through the vertical pipes c
is supplied to the bottom boxes e by means of the pipe h which communicates with
the interiors of the bottom boxes e by means of the pipes j. We place the lowest
part of the bottom e¹ of each of the bottom boxes e and each of the blow off or
mud pipes so that they shall be situate below those vertical pipes c which are
farthest from the point A at which the feed water enters each of the bottom
boxes e and by so placing the lowest part 2 of the bottom el of each of the
bottom boxes e and each of the blow off or mud pipes f we hinder or prevent
the vertical pipes c¹ c² which are furthest from the point A at which the feed water
enters each of the bottom boxes c, from becoming filled with and choked by the
impurities separated from the water while being heated in the fuel economiser, as
readily as they have hitherto been-The impurities separated from the water
while being heated in the fuel economiser which impurities are deposited in the
Lottom boxes e are blown off from time to time as may be required by means of
the blow off or mud pipes f.
-
Figs. 4 and 5 show another method of carrying this part of our invention into
effect. In Figs. 4 and 5 l. 1. are the vertical pipes usually employed in fuel
economisers The vertical pipes are connected in any suitable manner to the
bottom box m-We form the bottom m¹ of the bottom box m so that such
bottom m³ slopes or is inclined towards and leads to the blow off or mud pipe m
which blow off or mud pipe n is formed as part of the bottom box m and com-
municates with the blow off or mud pipe o-The blow off or mud pipe n is so
formed that its bottom n¹ slopes or is inclined towards the end n' of the blow off
or mud pipe n. Instead of being formed as shown in Figs. 4 and 5 of the drawing
hereunto annexed the blow off or mud pipe n may be so formed that its bottom
shall be horizontal.
The water to be heated while passing through the vertical pipes of the fuel
economiser is supplied to the interior of the bottom box m which communicates
with the interior of the vertical pipes l
The impurities separated from the water passing through the vertical pipes ¿
will fall either upon the sloping or inclined bottom m of the bottom box m or upon
the part n³ of the blow off or mud pipe n and will thence pass into the blow off or
mud pipe n.
The impurities separated from the water while being heated in the vertical
pipes which impurities are deposited in the blow off or mud pipe n are blown off
or removed from the blow off or mud pipe n from time to time as may be required
by means of the blow off or mud pipe o.

The second part of our invention relates to apparatus used for heating and
purifying water by means of the heat of the waste heated gases from steam
boilers and other furnaces which apparatus for heating and purifying water by
ineans of the heat of the waste heated gases from steam boilers and other furnaces
are similar in construction to the fuel economisers described in reference to the
first part of our invention and this second part of our invention consists in
improved arrangements, of apparatus by the employment of which improved
arrangements of apparatus we hinder or prevent the pipes of such apparatus for
beating and purifying water by means of the heat of the waste heated gases from
steam boilers and other furnaces from becoming filled with and choked by the
impurities separated from the water while being heated and purified in the said
apparatus for heating and purifying water by means of the heat of the waste
heated gases from steam boilers and other furnaces and enable the said impurities
deposited in the pipes and bottom boxes of such apparatus for heating and purifying
water by means of the heat of the waste heated gases from steam boilers and other
furnaces to be removed from such pipes and bottom boxes, more readily and with

page_text: greater certainty than has hitherto been possible-In carrying this part of our
invention into effect we apply to the said apparatus for heating and purifying
water by means of the heat of the waste heated gases from steam boilers and other
furnaces, bottom boxes similar to those above described in reference to the first
part of our invention and shown in Figs. 1, 2, 3, 4 and 5 of the drawing hereunto
annexed.
By this part of our invention we are enabled to hinder or prevent the pipos of
the apparatus used for heating and purifying water by means of the heat of the
waste heated gases from steam boilers and other furnaces from becoming as readily
filled with and choked by the impurities separated from the water heated and
purified in such apparatus as they have hitherto been and by this part of our
invention we are enabled to remove more readily and with greater certainty than
has hitherto been possible from the pipes and bottom boxes of such apparatus for
heating and purifying water by means of the heat of the waste heated gases from
steam boilers and other furnaces the impurities separated from the water heated
and purified in such apparatus for heating and purifying water by means of the
heat of the waste heated gases from steam boilers and other furnaces.
Although we have above described but two arrangements of our invention we
would have it understood that we do not confine ourselves to the use of our
invention precisely as above described in reference to and shown in the drawing
hereunto annexed as the mode of carrying our invention into effect may without
departure from the principles of our invention be varied, for instance, the blow off
or mud pipe may be formed as and placed where required and may be made to
slope or be inclined in any desired direction or in any desired degree.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is
1. For use in fuel economisers and similar apparatus a bottom box having its
bottom inclined or sloping towards and leading to a blow off or mud pipe for the
purpose and substantially as herein before described in reference to and shown in
and by the drawing hereunto annexed.
2. For use in fuel economisers and similar apparatus a bottom box having the
lowest point of its bottom and the blow off or mud pipe placed below the vertical
pipes farthest from the water supply pipe for the purpose and substantially as
herein before described in reference to and shown in and by the drawing hereunto
annexed.
