摘　　要：某电厂2号机组存在6^(#)低压加热器疏水不畅问题。通过详细分析和现场检查,指出造成疏水不畅的主要原因是DCS水位准确度不高、疏水管道阻力设计缺陷以及低加疏水系统存在漏点。提出切实可行的处理方案,旨在解决机组低压加热器疏水不畅的问题,提高机组抽气回热系统循环热效率和机组运行经济性。No. 6 LP heater of No. 2 unit in a power plant has poor drainage. Through detailed analysis and on-site inspection, it is found that the inaccuracy DCS water level, the influence pipeline resistance design and the leak in LP heater drain system is the main reason of No. 6 LP heater impeded drainage;since feasible solutions are presented to cope with the problem. The cycle thermal efficiency of the unit exhaust system and the operation economy of the unit are improved.
