The problems existing in circulating water system of condenser for unit no.1 in Huaneng Weihai Power Plant

such as the large allowance of output capacity for the circulating water pump

lower efficiency of the said pump

the air accumulation in water chamber of the condenser

as well as greater consumption of fresh water used for lubricating the water pump

etc.

affect economic efficiency of the unit in operation.After optimized technical retrofit carried out for the circulating water system

the unit can additionally generate electric power about 500 kW in summer

can save service power for circulating water pump about 150 kW in winter

the daily average-water saving being 400 t.
