UTILISATION METHOD OF THERMAL ENERGY GENERATED BY THERMAL POWER PLANT Russian patent published in 2015 - IPC F01K17/02 

FIELD: power industry.

SUBSTANCE: method involves utilisation of high-potential steam heat of production extraction and utilisation of low-potential heat of an oil supply system of bearings of a steam turbine with production steam extraction. The above utilisation processes are performed by means of a thermal engine with a closed circulation circuit, which operates as per a Rankine organic cycle, in which a low-boiling working medium circulating in the closed circuit is used as cooling liquid, with that, it is compressed in a condensate pump of the thermal engine, heated in an oil cooler, heated in a lower system water heater of the steam turbine, heated in an upper system water heater of the steam turbine, evaporated and superheated in a condenser of the steam turbine with production steam extraction, expanded in a turbine expander of the thermal engine and condensed in a heat exchanger - condenser of the thermal engine.

EFFECT: improving TPP efficiency due to utilisation of low-potential steam heat of heating extractions from a steam turbine for additional generation of electrical power.
