HEAT POWER PLANT OPERATION MODE Russian patent published in 2015 - IPC F01K17/02 F01K19/00 

FIELD: power industry.

SUBSTANCE: invention can be used in heat power plants (HPP) for utilisation of excess heat energy generated by HPP systems during its operation. Utilisation of excess low-grade heat of the return system water and oil supply system of steam turbine bearings and also utilisation of high-grade heat of industrial steam extraction are performed. The named utilisations are performed by means of the heat engine with the closed circulation circuit, operating according to Rankine organic cycle. The cooling liquid in the form of the low-boiling working body is compressed in the condensate pump and heated in the recuperative heat exchanger of the heat engine, heated in the oil cooler and in the heat exchanger cooler of system water, evaporated and overheated in the steam turbine condenser with production steam withdrawal, expanded in the turbine expander and the temperature is decreased in the recuperative heat exchanger of the heat engine and condensed in the heat exchanger condenser of the heat engine.

EFFECT: method provides increase of efficiency of heat power plant due to additional electric power generation at utilisation of excess heat energy generated by systems of heat power plant.
