Improvements in the Arrangements and Seating of Steam Bollers
and Feed Water Heaters.
I, JOHN HARGRAVES WILLIAMS, of The "Fitz," 47 Station Road, Keswick,
in the County of Cumberland, Boiler Inspector, do hereby declare the nature of
this invention to be as follows
-
My invention relates to steam boilers and its object is to improve upon the
method of seating at present adopted; to improve the flue airangements; to
provide economical feed heating or water heating appliances so placed as to absorb
waste heat ordinarily lost in the brickwork of the fluos, and also to arrange
auxiliary boilers for absorbing waste heat in conjunction with the main boilers.
In cairying one part of my improvements into effect as applied to an ordinary
Lancashire boiler. I mount the boiler upon cast or wrought on o steel stools or
brackets placed at intervals along the centre line of the bottom of the boiler shell
and I fill in the space between these stools with a brickwork wall, which wall I
deflect at the back of the boiler to one side so as to provide an expanded space
into which the hot gases from the flues can pass The furnace gases then pass
from the flues into the expanded space along one side and bottom of the boiler
across the bottom of the boiler at the front end along the bottom again to discharge
at the chimney end, the whole of the furnace gases thus pass first along one side
and bottom and then back along the other side and bottom before discharging at the
chimney. Suitable brick walls are provided in a usual manner and the fluc covers
at the top of the boiler are of the usual construction By this arrangement I allow
much larger flue space and more perfect combustion, a greater absorption of heat,
and I avoid the unequal expansion of the boiler caused by the ordinary method of
setung.
In can ying another part of my invention into effect which is principally applicable
to a battery of boilers, I preferably mount the said boilers upon stools as heiein-
before described and instead of forming the flues by means of buick walls dividing
the boilers, I arrange water tanks between the boilers to form the flue walls and
so shape those tanks as to produce any desued couhgination of flue. By these
devices the heat usually absorbed in the brickwork of the flues is applied to the
useful work of heating water, which may be either used as feed water or for other
purposes where hot water is required in industrial operations. Such dividing walls
may be either wholly or partly composed of tnoks and where necessary I supple-
ment the tanks by biickwork I prefer to set my dividing tanks also upon stools
to enable necessary repairs to be made.
In caying out another part of my invention, instead of open water tanks
incapable of tesisting pressie, I forni my division between boilers by means of
auxiliary boilers of sinaller external diameter. I may arrange for example a series
of three boilers forming a wall between two large Lancashire boilers, the three
boilers consisting each of a tube Inid horizontally one upon the top of the other
and connected by sunable tube pieces one with the other. These boilers are also
connected to the main boilers, the upper tube with the steam space of the main
boilers and the lower tube with the bottom of the main boilers The blow-off cock
for the two Lancashire boilers is preferably placed in the bottom of the lower
auxiliary boiler and by blowing off the mud from this boiler the mud formed in

page_text: the lower part of the two Lancashire boilers is also discharged. I mount the
auxiliary boilers also upon stools and apply suitable buckwork to complete the
division in order to form the necessary flues.
By these devices I am enabled to greatly improve upon the results ordinarily
obtained by Lancashire and other boilers.
It is to be distinctly understood that although I have herein before described
Lancashne boilers and one specific method of carrying my invention into effect in
each case, yet the invention may be applied in several ways to different types of
boiler, the object being in all cases to improve combustion and absorb a larger
amount of heat which is at present lost in the buckwork

Improvements in the Arrangements and Seating of Steam Boilers
and Feed Water Heaters.
I, JOHN HARGRAVES WILLIAMS, of The "Fitz," 47 Station Road, Keswick, in
the County of Cumberland, Boiler Inspector, do hereby declare the nature of
this invention and in what manuer the same is to be performed, to be particularly
described and ascertamed m and by the following statement
My invention relates to steam boilers and its object is to improve upon the
method of seating at present adopted, to improve the fluo arrangements, to
provide economical feed heating or water heating appliances so placed as to
absorb waste heat ordinarily lost in the buckwork of the flues, and also to arrange
auxiliary boilers for absorbing waste heat in conjunction with the main boilers.
Referring to the accompanying sheet of drawings,—
Figure is a transverse section though two Lancashire boilers arranged in
accordance with my improvements.
Figure 2 is a longitudinal section taken on the line I I, Figme 1
Figure 3 is a plan of the seating and stools, the two boilers being supposed to be
lifted out of their setting, and
Figure 4 is a transverse section through two similai boilers showing water tank
dividing walls.
In carrying one part of my improvements into effect as applied to an ordinary
Lancashire boiler or boilers, as A A Figure 1, I mount each boiler upon cast or
wrought iron, or steel stools or brackets, as B, Figures 1 and 3 placed at intervals
along the centre line of the bottom of the boiler shell and fill in the space
between these stools with a buckwork wall, as shown in plan Figure 3, which wall
I deflect at the back of the boiler to one side so as to provide an expanded
space D D to which the hot gases from the flues A' A' can pass. The Imunce
gases pass from the flues A' A' into the said expanded space D D then along one
side and bottom of the boiler, by way of the flues C and across the bottom of the
boiler at the front end along the bottom again by way of the flues E, to discharge
at the chimney end into the main flute F, the whole of the furnace gases thus pass
after leaving the boiler flues, hirst along one side and bottom and then back along
the other side and bottom before discharging at the chimney.
The arrows on the plan Figure 3 clearly indicate the duection of the currents.
Suitable brick walls are provided ma usual manner and the flue covers at

page_text: the top of the boiler are of the usual construction. By this arrangement I illow
much larger flue space and more perfect combustion, a greater absorption of heat,
and I avoid the unequal expansion of the boiler caused by the ordinary method of
setting
In carrying another part of my invention into effect which is principally
applicable to a battery of boilers, I preferably mount the said boilers as A A upon
stools B as hereinbefore descubed and instead of forming the flues by means of
brick walls dividing the boilers, I arrange water tanks as K Figure 4 between the
boilers to form the flue walls and so shape those tanks as to produce any desued
configmation of flue. By these devices the heat usually absorbed in the brickwork
of the flues is applied to the useful work of heating water, which may be either
used as feed water or for other purposes where hot water is required in industrial
operations. Such dividing walls may be either wholly or partly composed of tanks
and where necessary I supplement the tanks by buckwork. I prefer to set iny
dividing tanks also upon stools as G Figures 1, 2, 3 and 4 to enable necessary
repans to be made.
In carrying out another part of my invention, instead of opon water tanks
incapable of resisting pressure, I form my division between boilcis by means of
auxiliary boilers of smaller external diameter. I may arrange for example a
series of three boilers as II II II Figures 1 and 2 forming a wall between two
large Lancashire boilers as A A, the three boilers consisting each of a tube laid
horizontally one upon the top of the other and connected by suitable tube pieces
one with the other. These boilers are also connected to the main boilers, the
upper tube H with the steam space of the main boilers by menus of the pipe 1['
and the steam pipe L and the lower tube with the bottom of the main boilers by
means of pipes as H* The blow-off cock for the two Lancashire boilers is
preferably placed in the bottom of the lower-auxiliary boiler, and by blowing
off the mud from this boiler, the mud formed in the lower part of the two
Lancashne boilers is also discharged. I mount the auxiliary boilers also upon
Stools G and apply suitable brickwork to complete the division in order to form
the necessary flues.
By these devices I am enabled to greatly improve upon the results ordinarily
obtained by Lancashire and other boilers.
It is to be distinctly understood that although I have hereinbefore described
Lancashne boilers and one specific method of cairying my invention into effect in
each case, yet the invention may be applied in several ways to different types of
boilers, the object being in all cases to improve combustion and absorb a larger
amount of heat which is at present lost in the brickwork
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim 15,
1. Setting a steam boiler upon metal stools as and for the purposes berembefore
described
2. The arrangement of metal stools and brickwork flues hereinbefore described
whereby the furnace gases from the boiler flues pass into an expanded space at
the back of the boilci, thence along the side and bottom to the front and
across at the bottom of the front, and along the side and bottom of the boiler
to the back end again, where the gases discharge to the main chimney flue or
chimney.
3. Forming tho enclosing and dividing walls of water tanks instead of buckwork
to economise heat substantially as herein before described with reference to Figme 4
of the drawings.
4 Foming the enclosing and dividing walls of steam boilers instead of brick-
work to economise beat substantially as herembefore described, with reference to
Figures 1 and 2 of the diawings

page_text: 5. The special arrangement and construction of steam boilers, flues, and supports
as herein before described with reference to the accompanying drawings.
