THERMAL POWER PLANT WITH HEAT RECOVERY

摘要

In an energy conversion method and a thermal power plant for converting heat into mechanical or electric energy using a working medium, a vapor state in the working medium is generated at a first pressure in a steam generator. The vaporized working medium is expanded to a lower second pressure in a steam expanding device. An energy obtained by the expansion process is discharged. The expansion of the steam state is carried out using a saturation line of the working medium. The working medium is thereby separated into a non-condensed portion and a condensed portion in a separating device. The non-condensed portion is then compressed into a compressed non-condensed portion in a compressor. The compressed non-condensed portion is cooled and condensed into a compressed condensed portion. The compressed condensed portion and the initially condensed portion are then heated, and both portions are returned to the steam generator together.

主权项

1. Thermal power plant for converting energy by means of a working medium, which has:
a steam generator (25) for vaporizing the working medium at a first pressure, a steam expanding device for expanding the working medium present in the vapor state to a lower, second pressure, a condenser (36), which cools and liquefies the working medium let out of the steam expanding device, and a condensate pump (37), characterized in that the steam expanding device is designed in such a way that a working medium expanded by the steam expanding device has a condensed portion and a non-condensed portion, a separation device for separation of the condensed portion and the non-condensed portion and a compressor (51) for compression (5) of the non-condensed portion of the working medium are provided, whereby the non-condensed portion of the expanded working medium condenses at least partially through the condensed portion in the condenser (36).
