Multistep steam power operating method for generating electric power in a cycle and device for the implementation thereof

摘要

The aim of the invention is to further improve the closed cycle for generating electric power in such a way that efficiency is enhanced and general pressure and temperature requirements regarding the working fluid used are substantially reduced. The invention also provides an improved technical solution that meets the requirements of continuos operation at rated output despite fluctuations in load requirements. This is achieved through a multistep steam power operating method for generating electric power in a cycle by using an additional gaseous energy carrier to increase the pressure, the temperature and the volume of the working fluid in the cycle and by recirculating the working fluid in the cycle in such a way that continuously overheated steam is used as a working fluid. The invention can be used in the generation of electric power in a cycle.
