UNITED STATES PATENT QFFICE.
ALEXANDER VVINKLER, OF ST. PETERSBURG, RUSSIA. v
IMPROVEMENT IN FEED-WATER APPARATUS FOR STEAM-BOILERS.
Specification forming part of Letters Patent No. 131,489, dated September 17, 1872.
To all whom it may concern:
Be it known that I, ALEXANDER WINKLER, of St. Petersburg, Russia, have invented a method of resupplying steam engines with steam that has already been used therein, of which the following is a specification:
This invention has for its object an improved method of utilizing steam that has already been used in a steam-engine. The said invention consists in supplying steam-generators with exhaust steam, or steam that has already been used; in reconducting the exhaust steam of a steam-engine to the original boiler or steam-generator used for supplying the said steam-engine and in the manner in which these objects are effected, by the means hereinafter specified. It is therefore evident that by this invention the same quantity of steam is repeatedly used in the engine, and I thereby not only effect a considerable saving of fuel, but also obtain many other important advantages, as hereinafter set forth.
In practicing my said invention the exhaust steam or steam that has already been used in a steam-engine is reconducted into a reservoir, which, by means of a suction-pipe, is connect ed with a pressure apparatus, and with an injector of simple construction, provided with stop-cocks, and extending into the steam-space of the boiler or generator. As the theory, construction, and mode of action of the injector are well known, and form no part of this invention, it will be sufficient to mention here that,
for the attainment of my purposethat is to say, for reconducting the exhaust steam into the steam generator-I use the ordinary apparatus, with the difference that for the supply of the boiler the injector is not made to absorb water but steam that has already been used in a steam-engine.
Description of the Drawing.
- pressure-tube, which connects the inlet-gland g, Fig. 2, of the injector B with the steamspace of the boiler A. b is the steam-pipe which makes the connection between the steamspace of the boiler A and the steam-gland h, Fig. 2, of the injector B. d is a suction-tube, which connects the suction-space i of the injector B with the reservoir 0. c is atube, conducting to one or several steam-cylinders of the engine. 0 is a blow-0E cock. f is a valve for cleansing the reservoir (3. D and E are the steam and inlet cocks, placed in the .ends .of the tubes a and b, by means of which communication between the injector B and the steam space of the boiler A may be opened or interrupted. Between the injector B and the cock E a common lifting-valve is'inserted, the casingK of which is to be seen in Fig. 1. As the construction of such a valve is generally known and offers nothing new, a detailed illustration thereof is not needed. It is clear that the casing K, with the aforesaid valve, can also be inserted between the cock E and the boiler. As seen in Fig. 1, the pipes at and I) enter the boiler A above. the waterlevel X Y. The pipes at and b have a slight inclination toward the injector B, in order that the water of condensation and also all sediand also the pressure or supply apparatus, be-
come heated, and the parts of the latter are freed from any scum and condensation-water. The blow-0E cocks are then closed, and the entire arrangement is put in operation by opening the cooks D and E, by which the steam already used in the engine, and accumulated in the reservoir 0, is reconducted through the pipe a into the steam-space of the boiler A as it lifts the valve inclosed in the case K. The action of the injector B is regulated by the reservoir 0, in which the accumulation of the steam first takes place, so that the action of.
the same'is not interrupted, either during the communication of the reservoir 0 with the space behind the piston, or during the cutofl' of the steam by expansive engines. From this it is evident that the greater the volume of the reservoir 0 the more regular will be the work of the injector B. By opening the cook D more or less the action of the injector and also the degree of expansion of the steam behind the piston can be regulated in a more perfect manner than by a condenser.
The advantages of my method of utilizing the exhaust steam of an engine by reconducting it to the boiler are, first, a considerable saving of fuel, effected by the reconduction to the boiler of the latent heat used for the production of the steam. According to theoretical calculation this saving amounts to eighty or ninety per cent; second, a diminution of the required heatingsurface of the boiler, and in the quantity of Water contained therein, and in the weight and cost of the boiler; third, a saving in the construction of a condensing-engine, in the condenser, and also the air and water pumps, as pressure behind the piston can be diminished to the desired degree fourth, being enabled to use repeatedly the same quantity of steam, and, consequently, being less dependent upon the existence of water at the place Where the engine and'boiler are to be erected; fifth, the possibility of replacing common piston expansion engines by steam-turbines or other rotary steam motors, which Work With larger quantities of steam of less expansion.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
The steam-boiler of an engine, provided with an injector, B, exhaust-steam reservoir 0, suction-pipe (1, pressure -tube a, inlet gland g, steam-pipe b, gland h, and cocks D E, all c0mbined, constructed, and operating substantially as and for the purpose set forth.
