摘要
某厂一期3×600 MW机组原锅炉厂所供的锅炉系统中屏蔽了省煤器除灰系统,自机组建成投运以来,陆续出现了一些问题,经多方调研,决定加装省煤器除灰系统。该除灰系统不同于以往省煤器的除灰方式,不是将飞灰送至灰库或电除尘区,而是将飞灰直接送入电除尘入口烟道,再由电除尘输灰装置送入灰库。目前,该厂经过改造的3套省煤器除灰系统均已投入正常运行,提高了机组运行的安全性能和经济性能。
In the first stage project of 3 × 600 MW units in a power plant,the economizer ash handling system has been removed from the boiler system supplied by the former boiler factory.Some problems have appeared constantly since the units were put into operation.We decide to add the ash handling system to the boiler system after making some surveys.It conveys the ash to the flue of electrostatic precipitator inlet directly and then to the ash silo through electrostatic precipitator ash handling system instead of transporting the ash to the ash silo or electrostatic precipitator area.At present,three sets of ash handling systems reconstructed by this factory have been put into operation normally,and the safety and economic performance have been improved greatly
