IMPROVEMENTS IN AND CONNECTED WITH FUEL ECONOMIZERS
Year: 1885

page_text: I EDWARD GREEN, of Heath Old Hall, Wakefield, Yorkshire, Fuel Economizer
Manufacturer, do hereby declare the nature of my invention for "IMPROVEMENTS
IN AND CONNECTED WITH FUEL ECONOMIZERS "to be as follows:-
The object of this invention is certain new or improved details of Fuel
Economizers whether for heating feed water or for generating steam and
consists :-
1 In separating one or more pipes from the others of the series by a partition or
diaphragm in the upper box so that the cold water feed pipe which is at the top
allows the water to pass down tubes from one side of the partition and up to the
other tubes at the other side of the partition. This object can be attained also by
disconnecting the range of cold feed pipe at the top end. The tubes up which the
water flows are greater in number than that of the feed whereby the water is
broken into many streams and is therefore quickly heated before it leaves the
apparatus.
2 In forming the lower box deeper at the outer or exposed end than at the
inner end for the collection of sediment and in fitting said exposed part with, a
sludge cock for blowing off purposes.
6 In dividing the lower box into two compartments by an internal inclined
wing so that the sediment from the water in the tubes may slide from the upper
compartment into a lower one in which it can accumulate and be removed at
intervals as desired, portions of said box may be of pipe shape.
4 In making the boxes, top and bottom or one of them only, of separate castings
and providing them with flanges by which any two may be bolted together, the
pipes and their sectional boxes being interchangeable.

I EDWARD GREEN of Heath Old Hall, Wakefield, Yorkshire, Fuel Economizer
Manufacturer, do hereby declare the nature of my said invention and in what
manner the same is to be performed to be particularly described in and by the
following statement :-

The object of this invention is certain new or improved details of Fuel
Economizers whether for heating feed water or for generating steam and
consists :-
1 In separating one or more pipes from the others of the series by a partition or
diaphragm in the upper box so that the cold water feed pipe which is at the top
allows the water to pass down tubes from one side of the partition and up the
other tubes at the other side of the partition. This object can be attained also by
lisconnecting the range of cold feed pipe at the top end. The tubes up which the
water flows are greater in number than that of the feed whereby the water is
broken into many streams and is therefore quickly heated before it leaves the
apparatus, or is rapidly converted into steam.
2 In making the boxes, top and bottom, or one of them only, of separate
castings and providing them with flanges by which any two may be bolted
together, the pipes and their sectional boxes being interchangeable.
The details of my invention will be understood by reference to the annexed
rawings in which at Figure 1 I show a sectional elevation of a fuel economizer
with a partition or diaphragm A in the upper box B and with the cold water feed
nlet C so that the water entering at C may flow down the first row of the series
of pipes D into the lower box E and then up into the pipes F which are at the
other side of the partition A into the upper box B and away by the outlet G to
convey the hot feed water to a boiler if the apparatus be used for heating feed
water but if used as a steam generator the upper box B would form the steam
space and the steam generated being taken by the pipe G or in other convenient
manner.
The partition or diaphragm A may be formed in the casting of the upper box B
or affixed within it in any suitable manner so as to separate the feed water
space H from the hot water portion 1 of the upper box or the feed water eutry
may be by a separate pipe C, not forming part of the upper box B as at Figure 2,
the upper box B having the series of pipes F attached in the usual manner.
The second part of my invention will be understood by reference to Figure 3 in
which the top or bottom boxes B or E or both of them with flanges Q are made in
sections separate castings and interchangeable so that they may be bolted together
to form with their pipes F a fuel economizer of any dimension.

page_text: 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. The employment of a partition or diaphragm in the upper box of a fuel
economizer so as to separate the cold feed from the hot feed to a boiler or from
the compartment or portion of the economizer in which steam is generated as
herein before described and substantially as shown in Figure 1 of the annexed
drawings.
2. Admitting the cold feed water to a fuel economizer by a connection with the
lower box, said connection being separate and distinct from the upper box as
described and substantially as shown at Figure 2.
3. Making the boxes of fuel economizers in sections and with flanges as herein-
before described and substantially as shown at Figure 3 of the annexed drawings.
