利用中水降低直接空冷电站凝汽器背压的蒸发式冷却系统

Ancillary Evaporative Cooling System of Direct Air-cooled Power Station

国民经济发展需要电力的可靠稳定供给,本文介绍了一种利用经过处理的中水,作为直接空冷电站夏季辅助蒸发式冷却塔的补水,从而实现降低空冷电站夏季凝汽器背压,提高峰荷出力,节约煤耗,同时又实现污水回用,所以是一个节能又节水的系统技术。文中还分析了其推广应用的经济性。

Domestic economy development needs reliable and steady power supply.Introduced in this article is a system technology, which adopts treated middle water as the make up water of evaporative cooling tower of the direct air-cooled power station, to reduce the backpressure of the vapor condenser and therefore to increase the maximum generation capacity, to reduce coal consumption as well as to re-use of sewage.This is a systematic technology of saving energy and water, its economic feasibility is analyzed bellow.
