Thermal power plant
First Claim
1. In a method of operating a thermal power plant in which steam at a predetermined pressure is generated in a steam generating zone, and generated steam is expanded in an engine to produce mechanical work, the improvement which comprises withdrawing a first portion of the generated steam from said zone, compressing said first portion to a pressure higher than said predetermined pressure in a manner to increase the temperature of the compressed steam, and transferring thermal energy from said compressed first portion to a second portion of said generated steam prior to expanding said second portion in said engine.

Abstract
A portion of the steam produced in a nuclear power plant at relatively low pressure is substantially adiabatically compressed, and the compressed, heated steam is employed for superheating the steam supplied to one or both stages of a steam turbine which drives the generator. The energy gained by superheating may be greater than that spent in compressing a portion of the steam.

8. In a thermal power system including a source of thermal energy, steam generator means connected to said source for vaporizing water to steam by the thermal energy of said source, a steam-operated engine, and conduit means for supplying steam from said generator means to said engine as a working fluid, the improvement which comprises:
-
a. compressor means connected to said steam generator means for receiving steam therefrom, for compressing and for thereby heating the received steam; and b. heat transferring means in said conduit means connected to said compressor means for transferring thermal energy from said compressed, heated steam to said working fluid. - View Dependent Claims (9, 10, 11, 12, 13, 14)
