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 generated at heat power plants (HPP). In the heat power plant the heat exchanger-cooler of network water is used which is installed on the network water return pipeline, the condenser unit, with production steam extraction and the oil supply system with the oil cooler for lubrication of its bearings. The utilisation of low-grade heat of the oil supply system of steam turbine bearings with production steam extraction, utilisation of low-grade heat of return network water and utilisation of high-grade heat of 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 and utilisation of excessive low-grade heat of return network water for additional electric power generation.
