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

FIELD: power industry.

SUBSTANCE: invention relates to power engineering and can be used in the heat power plants (HPP) for utilisation of waste low-grade heat in condensers of steam turbines of heat power plants, utilisation of low-grade heat of oil supply system of bearings of the steam turbine, utilisation of low-grade heat of oil supply system of bearings of the steam turbine with production steam extraction, utilisation of low-grade heat of heating extraction steam from the steam turbine and utilisation of high-grade heat of industrial steam extraction. The method of utilisation of heat energy generated by heat power plants (HPP) includes pumping of the spent steam from the steam turbine into steam space of the condenser for condensation on surface of condenser tubes with cooling liquid, pumping of condensate into the regeneration system, meanwhile the heating performance steam from the steam turbine extractions is pumped to the steam space of the lower and upper system heaters for condensation on surfaces of the heated tubes of system heaters with cooling liquid, and in the steam turbine the oil supply system with oil cooler for steam turbine bearings is used. In heat power plants the condensation unit is used which has the steam turbine condenser with production steam extraction and oil supply system with oil cooler for bearings and in addition utilisation of high-grade heat of industrial steam extraction, utilisation of low-grade heat of oil supply system of steam turbine bearings and utilisation of low-grade heat of oil supply system of steam turbine bearings with production steam extraction are performed, meanwhile all named utilisations are performed by means of the heat engine with the circulation circuit according to Rankine organic cycle with the low-boiling working body which is compressed in the condensate pump of the heat engine, heated in the steam turbine condenser, in the oil supply cooler, in the oil cooler, in the lower and upper system heaters, heated and evaporated in the steam turbine condenser, expanded in the turbine expander of the heat engine and condensed in the heat exchanger condenser.

EFFECT: increased efficiency ratio of heat power plant.
