UTILIZING EXHAUST-STEAM.
SPECIFICATION formingpart of Letters Patent No. 259,323, dated June 13, 1882.
Application filed August 3, 1881. (No model.)
To all whom it may concern:
Be it known that I, HARVEY T. LITGHFIELD, of Hull, in the county of Plymouth and State of Massachusetts, have invented a new and useful Improvement in the Process of Utilizing Exhaust-Steam, of which the following is a specification.
My invention has forits object the utilization of the exhaust-steam of engines, and retaining and utilizing the same without the loss of heat and without anycondensation except that due to radiation; audit consists in certain arrangements ofparts in which the steam, or the steam and water, or water alone, may be fed to either of the boilers from each other,when it is so desired, Withouta pump, and also by the same means regulate the pressure of steam in the working-boiler, as will hereinafter more fully appear.
In the drawings, Figure 1 illustrates all the various parts of my invention. Fig. 2 is a side elevation of the same. Fig. 3 is an enlarged view, showing certain details of the apparatus.
The same letters denote like parts in all the figures.
A is a low-pressure boiler or receiver; B, the hi gh-pressure boiler b, the superheater, located in rear of the high-pressure boiler and exposed to the heat of the furnace. D D is a compound engine; E, the feed-pipe to engine; F, the exhaust-pipe from same; H, the superheated-steam pipe having nozzle G. I is a pipe leading to each of the boilers, and also to the water-tank. J K are branch pipes provided with cocks V U. L is the superheatedsteam pipe leading from the superheater to the branches K J. M is the water-tank, and N the pipe]eadingtherefrom. The liquids and gases passing through all these pipes are regulated by cocks and valves. 0 is the pipe which conveys the steam from the high-pressure boiler to the superheater, which is also controlled by a cock. F is a pipe which leads off to heat buildings, or for other purposes.
While the high-pressure boiler will generate sufficient quantity of steam for all ordinary purposes, it often happens that a greater quantity of steam'is required. In that case the lowpressure boiler may be used for generating steam for that purpose.
Operation: Steam is generated in the highpressure boiler. It is then conveyed to the superheatcr. WVhcn the engineis at work the superheated steam is used to inject the exhaust of the engine into the low-pressure boiler or receiver. A portion of the superheated steam is used for injecting water from the high-pressure boiler into the low-pressure boiler, and when water is required for either of these boil; ers it is used for injecting it; but when too much water accumulates in the receiver the cock V is shut off and the cooks S, T, U, and \/V are opened. Communication between the boilers is now established, and also with the water-tank, to such an extent as to permit a small quantity of water from the tank to enter the injector. Steam is then let on, when the water from the low-pressure boiler is injected into the high-pressure one. Thus it will be seen that the feeding device is also a governor for regulating the pressure and supply, the hi gh-pressure boiler being of sufficient capacity to retain any surplus pressure.
Having described myinvention, what I claim as new and useful, and desire to secure by Letters Patent, is
The combination, with an apparatus for utilizing the exhaust of engines, of the branch injecting-pipes, communicating with two or more boilers and with the water-tank, and adapted to ,force liquid from one to the other, or to either of them, in the manner shown and described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
HARVEY T. LITOHFIELD. Witnesses:
J. H. ADAMS, B. OHARA.
