300MW机组轴瓦温度异常原因分析及对策

300 MW机组在运行和启停过程中会出现轴瓦温度异常现象,尤其是在机组停机惰走过程中更易导致轴瓦乌金面烧损.结合建厂以来的一些改进措施,分析目前存在的主要问题,制定防止轴瓦温度过高的措施.;Jiaxing Power Plant contains two 300 MW and four 600 MW units.Its often happens that the temperature of the operation turbine bearing rises to an unusually high level,especially during the periods of starting up and shutting down.The metal over the bearing is burnt out.After analyzing the causes,ways of preventing the shaft's bearing temperature from rising is introduced
