HEAT POWER PLANT OPERATION MODE Russian patent published in 2015 - IPC F01K17/02 F01C1/00 F01K23/00 

FIELD: power industry.

SUBSTANCE: spent steam is supplied from the steam turbine into the steam space of the condenser and the produced condensate by means of its condensate pump is supplied to the regeneration system. In the heat power plant the heat exchanger-cooler of network water is used which is installed on the network water return pipeline, and also 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 Rankine organic cycle where the cooling liquid is the low-boiling working body.

EFFECT: improvement of efficiency of heat power plant at the expense of full utilisation of waste low-grade heat and utilisation of excess low-grade heat of the return network water for additional generation of electric energy, increase of service and reliability of operation of the steam turbine condenser and decrease of thermal emissions into environment.
