PROCESS AND DEVICE FOR OPERATING THE WATER-STEAM CIRCUIT OF A THERMOELECTRIC POWER STATION

摘要

The invention discloses a kind of circuits handled in thermal power plant steam, such as thermal power plant thermoelectric power plant, in heating or combined heated and power station, condensate regenerator section (20), steam generator (30) and steam turbine (10) and condenser (12) and subsequent condensate preparation unit (14) are arranged to make downstream end and have at least one condensate pump (16) at its upstream. Steam diversion from steamturbine (10) and/or the condensate of preparation is applied in the pre-heat section (20) from (32) of steam superheating, therefore be heated before it and be supplied to steam generator (30). Pretreatment is carried out before condensate liquid and reaches pre-heat section (20) and needs, then not degasification, while it is flowed through in preheating section (20).
