UNITED i" STATES PATENT OFFICE.
BENJAMIN CRAW'FORD, OF PITTSBURG, PENNSYLVANIA.
IMPROVED ARRANGEMENT 0F FEED-WATER-HEATING PIPES OF STEAM-ENGINES.
Specification forming part of Letters Patent No. 31,874, dated April 2, 1361.
"0 all whom, I5-may concern:
Be it known that l, BENJAMIN CRAWFORD, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in IIeating-Pipes for Boilers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, in Which- Figure l represents a vertical cross-section, Fig. 2 a top View, and Fig. 3 a rear view, of the apparatus.
Similar letters of reference in each of the several figures indicate corresponding parts.
The nature of my invention consists in a peculiar arrangement of feed-Water-heating pipes of steam-boilers, as hereinafter described.
To enable others skilled inthe art to make and use my invention, I Will proceed to describe its construction and operation.
The boilers H H and iiues J J are of the usual construction; but the system of pipes supplying the boilers With Water is arranged in a peculiar manner, the purpose of which is to use the Waste heat escaping through the tlues for the heating of the feed-Water before it enters the boilers. The vertical ends A of horizontal pipes B are connected to a forcepump at the rear end of the boilers II l-I. The Water passes from the pump through the pipes A B and curved portions C of the pipes B B into the fines or chimneys J J. Inside of the fines or chimneys there are a pair of chambers or enlarged pipes, as seen at D D, to which the pipes B B are attached. From these chambers a number of pipes (marked E) pass down in a zigzag manner, so as to ex-V tend across the whole areaV of the lues and enter the chambers F F. The lower parts of the pipes E and chambers F F being arranged immediately above the boiler-lines, the pipes I I, of the same size as the pipes B B, pass from the chambers F F through the rear of the fines and immediately under the tile or arch of the furnace to the rear end of the boiler, Where they connect With the latter at R, or may extend to the check-valve of the stand-pipe.
The feed-Water in passing through the pipes E is heated to a high degree by the Waste heat escaping from the boilers through the hues, after Which it receives still additional heatfrom the furnacebelowinpassingthrough the pipes I I to the rear end of the boiler, so that the temperature of the feed-water by the time it enters the boilers may be raised as high, or nearly so, as that contained Within the boilers, which produces not only a large saving of fuel, but also renders the boilers free from contraction by being supplied With Water at a low temperature.
What I claim as my invention, and desire to secure by Letters Patent, is-
The arrangement, in the flues J J of a boiler,
of the transverse pipes or chambers D D and series of zigzag pipes E E, in combination With suppl y-pipes A B C, which are arranged to run from the doctor or pump along the top of the boilers, and the induction-pipes I I, Which are arranged along and to run from the lues J J under the arch or tile of the furnace to the interior of the boiler, substantially as herein set forth.
