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

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.
