摘要
介绍了600 MW机组锅炉回转式空气预热器进行在线高压水洗降低其前后压差的试验和冲洗过程,分析和解决了应用高压水冲洗技术的几个问题.结果表明：高压水冲洗可使空气预热器前后烟气压差下降0.8～1.0 kPa,风机运行电流下降110 A,获得明显的收益.
An online high-pressure water washing test was carried out for the boiler rotary air preheater in a 600 MW unit with the purpose of reducing the pressure difference before and after the preheater, so as to analyze and solve the problems occurring in application of the high-pressure water washing technology. Results show that the high-pressure water washing can reduce the gas pressure difference before and after the air preheater and the running current of fan respectively by 0.8 - 1.0 kPa and 110 A, indicating a significant benefit.
