UTILISATION METHOD OF THERMAL ENERGY GENERATED BY THERMAL POWER PLANT Russian patent published in 2015 - IPC F01K17/02 F01K19/00 

FIELD: power industry.

SUBSTANCE: invention can be used at thermal power plants (TPP) for utilisation of excess thermal energy generated by systems of TPP during its operation. Utilisation of low-potential heat of an oil supply system of bearings of a steam turbine and an oil supply system of bearings of a steam turbine with production steam extraction is performed, as well as utilisation of high-potential steam heat of production extraction is performed. All 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. A low-boiling working medium circulating in the closed circuit is compressed in a condensate pump, heated in a recuperative heat exchanger, in an oil supply cooler of bearings of the steam turbine and in an oil cooler of a condensing plant, evaporated and superheated in a condenser of the steam turbine with production steam extraction, expanded in a turbine expansion engine, its temperature is decreased in the recuperative heat exchanger and condensed in a heat exchanger - condenser of the thermal engine.

EFFECT: improving TPP efficiency due to additional generation of electrical power at utilisation of excess steam energy generated by TPP systems.
