正压直吹式制粉系统泄漏原因分析及治理措施

Analysis on reasons of leakage defect of positive-pressure direct-fired system and treatment measures

对某电厂2台660 MW燃煤汽轮发电机组正压直吹式制粉系统泄漏原因进行了分析,提出不同漏点的治理方案,有效消除了制粉系统的泄漏缺陷。

The reasons of leakage defect of positive-pressure direct-fired system of two 660 MW coal-fired turbine generator units in a power plant were analyzed. The treatment measures for different leakage points were proposed. The leakage defect of the coal pulverizing system was eliminated effectively.
