摘要
Abstract
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.关键词
