JAMES WELSH, OF PLYMOUTH, PENNSYLVANIA.
FEED-WATER HEATER.
SPECIFICATION forming part of Letters Patent No. 310,968, dated January 20, 1885.
Application filed June 9, 18t4.
To all whom, it may concern.-
Be it known that I, JAMES WELSH, a citi zen of the United States, residing at Plymouth, in the county ofLuzerne and State of Pennsylvania, have invented a new and useful Feedater Heater for Boilers, of which the fol lowing is a specification, reference being had to the accompanying drawings.
This invention relates to feed-water heaters for steam-boilers; and it has for its object to provide means for supplying the boilers with hot water, from which steam may be generated, and thus there will be no necessity of heating cold water in the boiler, and steam may be obtained in a very short time.
A further object of the invention is to provide a water-tank around the smoke-stack, which will be continually supplied with water and heated by the products of combustion passing up the smoke-stack, the latter being thus held from blowing over and from being burned out, as often occurs.
WVith these and other objects in view the said invention consists in certain details of construction and combination of parts, as hereinafter set forth, and particularly pointed out in the claim.
In the accompanying drawings, Figure l is a side view illustrating my invention applied to a smoke-stack, and showing the connection between the water-tank and the boilers. Fig. 2 is a horizontal section of the same. Fig. 3 is a vertical longitudinal section of the watertank.
Like letters are used to indicate corresponding parts in the several figures.
Referring to the drawings, A designates the smoke-stack, of the usual cylindrical form; and B designates a water-tank disposed around the same, and formed of substantially the same shape, the ends or heads 0 G of the tank being closed and secured to the outer sides of the smoke-stack. In this manner the smokestack is braced and held from being blown over by the wind. The watertank is filled with water by the pump used to feed the boilers, said pump connecting by a pipe, D, with said tank, seas to keep up a continuous supply thereto. It will be seen that the waste heat of the s1noke-stack arising from the (No model.)
passage of the smoke, gases, and other products of combustion up the same will serve to heat the water contained in the tank, and should steam be generated in the tank it will be permitted to escape through the openings E E, formed in the upper end thereof. A pipe, F, is connected with the lower end of the tank, and serves to allow the trash and other matter accumulating in the bottom of the tank to run off as found .desirable. A distributingpipe, G, connects with the water-tank and communicateswith three or more branch distributing-pipes, H. H H, running to boilers I I I, so as to keep the said boilers supplied with the necessary amount of feed-water, suitable cocks, J J J, being arranged in the branch pipes, and adapted to shut off the flow as desired.
K K designate smoke-fines connecting the furnace with the smoke-stack.
The operation of my invention will be readily understood from the foregoing description, taken in connection with the annexed drawings. The water-tank is supplied with water, and the smoke and gases from the furnace pass through the smoke-tines into the Smokestack and upward through the same, the heat from the smoke, gases, and products of combustion serving to heat the water in the tank. The boilers may be supplied with any amount of this feed-water by opening the cooks of the branch pipes. Should steam accumulate in the water-tank, it will be allowed to escape through the openings E E, formed in the upper end thereof, and thus there will be no danger of accidents by the explosion of the tank. It will be seen that the heads of the water-tank are secured to the smoke-stack so that the latter will be braced and prevented from being blown over by the wind. The size of the tank is made to suit the size and shape of the smoke-stack, while the number of supply and distributing pipes may be multiplied to suit the requirements. Since the water-tank is arranged above the level of the 9 5 boilers, the pressure of water in the tank will prevent the escape of steam therein.
My improved feedwater heater is simple, inexpensive, and may be applied to all classes and styles of boilers, to supply the same with ICO provided in the upper end of the latter, and a distributing-pipe, G, communicating with the tank, and connecting with three or more branch pipes, H, arranged and operating as and for the purpose set forth.
In testimony that I claim the foregoing as my own I have hereto aifixed my signaturein preshot water, from which steam may be generi ated in a very short time. Since the tank is arranged around the sn1oke-stack,itWil1 prevent the latter from being burned out, which often occurs in the ordinary arrangement.
Having described my invention, I c1ai1n The combination, with the smoke-stack A,
of a water-tank, 13, built around the same, the ence of two Witnesses. pipes K, passing through the Water-tank and opening into the smoke-stack, to deliver the smoke and products of combustion thereto, a supply-pipe, D, for the tank, perforations E,
