摘要： PROBLEM TO BE SOLVED: To compress steam by adding the speed energy of steam exhausted from a turbine by an ejector effect. SOLUTION: In case of a centrifugal type compressor, turbine blades 7 and 7 are set in the radial direction at the rear surface of the blades, and a guide vane 4 is set at the rear side of the turbine final end, so as to compose to make the steam exhaust direction the same. In the case of an axial flow type compressor, turbine blades 7 and 7a are set at the rear side in the radial direction of the blades 7 and 7a, guide vanes 8 and 8a are set at the rear side of the turbine blades, and the direction of the steam exhausted from a steam compressor, and the direction of the steam exhausted from a steam turbine, are made the same.

摘要： PURPOSE: To improve the coverall efficiency of a fuel cell power plant by extracting the waste heat of a fuel cell power generating device as steam via a steam generator, boosting and detecting pressure of the boosted steam to conduct required the steam by a compressor to feed it to a steam header, control of fed steam pressure. CONSTITUTION: Waste heat of a fuel cell power generating device 1 is extracted as steam by a steam generator 2, and this steam is boosted by a compressor 4 to be fed to a steam header 5. At this time, steam pressure on the secondary side of the compressor 4 is detected by a pressure sensor 7. When the detected pressure becomes lower than the steam pressure in the steam header 5, regulating valve 9 is controlled by a controller 10, high-pressure air is fed from an air source 8, and the steam pressure fed to the steam header 5 becomes practically higher than the steam pressure in the steam header 5. The overall efficiency of a fuel cell power plant can thereby be improved.

摘要： The operating process involves expanding vapour, starting from the saturated state, in an expansion machine (1), so that some of the vapour or steam is condensed. The condensation is separated out in a device (2) and compressed by a feed pump (6) to output pressure. The remaining steam is compressed by a compressor with heat being yielded to the feed water preheater (7) roughly polytropically. Steam still remaining is isothermally compressed, yielding heat to the steam generator (8) to output pressure. The condensate separated out is heated to saturation temp. in the feed water preheater and partly compressed in the steam generator.

摘要： 207,862. Rezsny, K., Halasz, E. v., and Paulini, A. Sept. 5, 1922. Engines working on special systems or cycles. -In an engine using superheated steam, the exhaust is discharged through a liquid and then compressed to the pressure in the superheater into which it is discharged. Alternatively, the steam to be compressed for the next cycle may be supplied by a surface condenser in which the exhaust steam of the preceding cycle has been condensed. The compression may be effected in the cylinder itself, if the engine is a reciprocating engine, or in a compressor in one or two stages. The engine may work on a two or four stroke cycle. In the four-stroke cycle engine, Fig. 1, steam at atmospheric pressure and at 100‹ C. is sucked past valve 2 from vessel 6. It is then forced at about 40 atmospherics through chambers 9, 12, and coil 10 wherein it is heated to about 700‹ C. The power stroke is effected with expansion on opening valve 14. The return, exhaust stroke is effected on opening valve 2, and the steam passed into the water in vessel 6 through a perforated pipe 15. The separated oil is let off by pipe 20, fresh water being supplied by pipe 21. Fresh steam is drawn into the cylinder through pipes 4, 3 past valves 18, 2. By using a double-ended cylinder with transverse ports and compression and expansion in opposite ends, the engine is worked on a twostroke cycle. The compressed steam scavenges the cylinder, which may be double-acting, in which case the fresh steam is prepared in a separate compressor. Steam may be taken from another engine instead of the vessel 6. In the turbine plant, Fig. 3, superheated steam enters at 29 and the exhaust passes to the reservoir 6 from which steam is transferred to the superheater by a single or multiple compressor which may be turbo-compressor on the main shaft. A construction is described wherein the exhaust from a reciprocating engine is used in a fourstroke engine. A part of the power cylinder 1 may be cooled. The chamber 6, Fig. 1, might comprise a condenser with pressure below the atmosphere and the suction may be effected from steam above atmospheric pressure. Starting may be effected by injecting water or steam into the superheater, or by using an auxiliary boiler.
