HEAT POWER PLANT OPERATION MODE

摘要

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 the pump is supplied to the regeneration system. 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. 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 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 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.3 cl, 1 dwg
