摘要
燃煤电厂实施污染物超低排放以后,NH4 HSO4的生成加重了空气预热器堵塞,影响了机组的安全运行.介绍了干冰冷喷技术清除空气预热器换热元件表面结垢的方法和应用效果,为解决NH4 HSO4引起的空气预热器堵塞问题提供了新的技术路线.
After application of the ultra-low emission of pollutants in coal-fired power plants,the ammonium hy-drogen sulfate(ABS)aggravates the blockage of the air preheater and affects the safe operation of the boiler system.It introduces the method and application of dry ice cold blasting technology to remove the scaling on the surface of heat exchanger elements of the air preheater,and provides a new technical solution to solve the blockage problem of the air preheater caused by ammonium hydrogen sulfate.
