To all whom Vil may concern: 4
V Be it known that 1, SPENCER Oris, a citizen ofthe United States, residing at Chicago, in the county ot' Cook and State of Illinois, have invented cert-.iin new andjuseful Improvements in Steam-Transformers, of
'which the following is a. specification.
Myinvention relates to steam transornwrs; and has l for its objectto produce a device in which superhealed steam at high pressure may be reduced in temperature, the pressure lowered, and at the same time the amount of working fluid increased. To this end my invention consists in the combinations and details hereinafter set forth and claimed.
n the figure of the drawing', I have shown a longitu-l dinal elevation, partly in section, of my improved transformer. 'i
Referring to the drawing in which I have shown my device specifically' applied to a nozzle for the introduction of steam to the working parts oi a'. steam turbine, a represents the end ot' thel nozzle at the point -where the steam is admitted to the turbine.
a represents 'an expansion chamber formed .adjacent the nozzle. Steam is introduced into the end a2 of the expansion chamber, this end being opposite the nozzle end. The walls oi the opening a2 are suitably screw threaded and receive a casing b,.suitably screw threaded at one end. This casing b is hollowed as shown and receives a block c formed with a longitudinal passageway c. The block o is circumfcrentially reduced at its forward end, thereby forming a chamber b inthe casing b. I also provide passageways b2 leading from the chamber b to the orifice b, ahd it will be observed that the passageway c 'also communicates with this orifice. suitably connected with the passageway c is a. steam-pipe f, and suitably connected with the chamber b is a water-supply pipe d.
In operation, superheatcd steam at high temperature and at high pressure, such as, for instance, is generatcd in boilers of the flasher type, is admitted to the expansion chamber a through the passageway-d. As is well-known boilers of the flasher type areadapted for the production o small quantities of steam at high pressure and temperature. It is not essential that steun at this temperature be used for the purpose of operating a steam turbine, consequently, in order to operate the vulve.
l reduce the temperature ofthe steam and at the same time increase the quantity of working fluid, I propose to admit through the pipe (l a suflicient quantity of water Vwhich will be drawn through the passages (l2 by the steam entering the'chainber through the passageway c in the form of inesprtty. The water at this point will be converted into steam by the abstraction of part of the. heat from the superheated steam, as will be readily understood.
In order to regulate the supply of water to the tomperature of the steam within the chamber, so that the supply oi water may not be greater than can be oonverted into steam without reducing the temperature of the steam within the chamber below the desired point, Iv providel in the water supply pipe l a valve df, which may be conveniently operated through a diaphragm (F connected with a thermostatic regulating device e by a pipe e.' When the temperature within the chamber falls below a predetermined point the thermostat e within the chamber will cause the opera- -tion of the valve ll to shut off the supply o water.
-heated steam to convert'the water supplied to the chamber into steam, thus furnishing au additional quantity ot' working fluidv to'be supplied to the engine.
It will also bescen that my deviceis automatic in its operation.
I claim:
1. In a steam ltransformer, n chamber, a steam 'inlet lending thereto, n wuter inlet surrounding; the steam'inlet. n. wnter supply pipe connected to the water inlet, :l vulve in the water supply pipe, u thermostat within the chamber, :1nd means conuectngthe thermostat withthe valve to 2. In :i steam transformer, n closed chamber, u steum supply, inezns whereby the stezun supply causes n flow of water into the chamber, and means governed by the temperature within the chamber for regulating the amount of wuter'delvered thereto SPENCER. OTIS.
