SYSTEM CONTAINING LOW PRESSURE STEAM TURBINE (VERSIONS) AND COMBINED CYCLE SYSTEM

摘要

FIELD: power industry.SUBSTANCE: invention relates to the unit for removal of part of heat released from the low pressure steam turbine in the steam generator through the feedwater heater, and from the power gas-turbine combined cycle plant. The plant contains the low pressure steam turbine, the air cooling condenser which has flowing connection with the low pressure steam turbine and intended for reception of part of steam from the exhaust flow of the steam turbine, the feedwater heater which has flowing connection with the low pressure steam turbine by the pipeline and intended for reception of part of input steam from the low pressure steam turbine and the condensate pump which has flowing connection with the air cooling condenser and the feedwater heater and intended for reception of the condensed fluid medium from the air cooling condenser and the fluid medium which is discharged from the feedwater heater. Also the system for removal of part of heat and power gas-turbine combined cycle plant are also described.EFFECT: increase of efficiency and productivity of the low pressure steam turbine and the system as a whole are provided.10 cl, 2 dwg
