DOUBLE-REHEAT POWER GENERATOR WITH AN ULTRA HIGH PRESSURE CYLINDER AND A HIGH-INTERMEDIATE PRESSURE CYLINDER EACH HAVING ADDITIONAL HEAT RECOVERY TURBINE STAGES
DOUBLE-REHEAT POWER GENERATOR WITH AN ULTRA HIGH PRESSURE CYLINDER AND A HIGH-INTERMEDIATE PRESSURE CYLINDER EACH HAVING ADDITIONAL HEAT RECOVERY TURBINE STAGES
A double-reheat power generator with an ultra high pressure cylinder and a high-intermediate pressure cylinder each having additional heat recovery turbine stages, including steam exhaust of the ultra high pressure cylinder having additional heat recovery turbine stages, that is, first extraction supplies steam to a first high-pressure heater. New second, new third and new fourth extractions of the ultra high pressure cylinder having additional heat recovery turbine stages supply steam to second, third and fourth high-pressure heaters respectively; a new fifth extraction of the HP-IP cylinder having additional heat recovery turbine stages supplies steam to a deaerator; a new sixth extraction of the HP-IP cylinder having additional heat recovery turbine stages supplies steam to an air-preheater; and an air-preheater drainage pump used for water draining of the air-preheater connects to the deaerator.
