350MW直接空冷机组空冷岛冬季运行优化研究

Optimization Research on Winter Operation of Air-cooling Island of 350 MW Direct Air-cooling Unit

空冷凝汽器的防冻对于直接空冷发电机组在冬季的安全可靠启停及运行至关重要。针对北方某直接空冷机组在冬季启动、停机过程以及低负荷运行阶段存在的防冻问题,介绍其启停及运行过程中对应的防冻运行监视、调整及解冻措施。

Antifreezing of direct air-cooling condenser in winter is very important for safe and reliable start-stop and normal operation of unit. According to the antifreezing problems of a direct air-cooled unit during start-stop process and low load operation in North of China, the corresponding antifreezing methods including monitoring, adjustment and thawing measures were introduced in this paper.
