国内外火力发电多年来的运行经验表明.正确使用吹灰器对防止和清除锅炉水冷壁管、过热器、省煤器、空气预热器等管道外部结焦、积灰及提高热效率等有显著效果。然而,随着发电机组和锅炉容量的增大,吹灰器数量增加,单靠运行人员逐个进行手动操作会使运行人员负担过重。因此,在提高锅炉热效率的同时减轻运行人员的劳动强度,实现吹 Operating experience of thermal power generation both at home and abroad over the years shows that the correct use of soot blowers has significant effects on preventing and eliminating external coking, fouling and thermal efficiency improvement of water-cooled wall tubes, superheaters, economizers, air preheaters and the like in boilers . However, as the capacity of generating units and boilers increases, the number of sootblowers increases. Operating personnel alone can overburdened operators by manually operating one by one. Therefore, to improve the thermal efficiency of the boiler while reducing the labor intensity of operators to achieve blow
