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

FIELD: power industry.

SUBSTANCE: invention relates to the method of utilisation of heat energy at heat power plants (HPP). In the heat power plant the condensation unit is used which has the steam turbine condenser with production steam extraction and the oil supply system with the oil cooler for lubrication of its bearings. In addition the utilisation of high-grade heat of industrial steam extraction and utilisation of low-grade heat of oil supply system of bearings of the steam turbine with production steam extraction are performed. The named utilisations are performed by means of the heat engine with the closed circulation circuit, operating according to Renkin organic cycle where the cooling liquid is the low-boiling working body circulating in the closed circuit.

EFFECT: improvement of efficiency of heat power plant due to full use of waste low-grade heat for additional electric power generation.
