Study on Heat Recovery Technology of Closed Cooling Water System for Nuclear Power Plants

摘要: 提出了一种能回收闭式冷却水系统余热的节能减排技术方案,可在凝结水温度不大于34℃的条件下利用凝结水来代替海水吸收闭式冷却水系统中的余热。文中给出了红沿河核电厂1000 MW级机组的应用分析实例。结果表明,通过回收闭式冷却水系统余热可增加机组出力约1.5 MW,减少温排水海洋污染约2.1×10⁷ t/a,产生经济效益约3.58×10⁶元/a。

Abstract: A new technology of energy saving and emission reducing which can recover the heat of closed cooling water was proposed.The condensate is used to absorb the heat from the closed cooling water when the condensate temperature is not greater than 34℃,instead of sea water.An application case for Hongyanhe 1000 MW class nuclear power plant is given to show that with this method,the unit output would be increased about 1.5 MW,the warm water emission would be reduced about 2.1×10⁷ t /a and the economic benefit would be increased about 3.58×10⁶ RMB each year.
