CONDENSATE EXTRACTION PUMP

CONDENSATE EXTRACTION PUMP SYSTEM DESCRIPTION Condensate from condenser hot-well is pumped through LP heaters up to deaerator by Condensate Extraction Pumps (3 nos. CEP).  In full load operation two pumps will be in operation and one in standby condition. CEP is of vertical sleeve type multi stage pump.  So it is called as turbine type pump. Each pump is directly driven through an electric motor and is delivering to condensate water. All the CEP are connected to a common header through a non-return valve and motorized discharge valve. From that discharge header condensate passes through Gland Steam Condenser (GSC) and through a Deaerator control station. By modulating this valve Deaerator level is maintained according to the set point given. A recirculation valve is provided before Deaerator level control valve to maintain a minimum condensate flow through the pump & GSC. The main condensate is passed through Condensate Polishing Unit, GSC, LP heater-1, LP hea
