目前,循环流化床锅炉需要运行的时间正在不断延长,预防磨损的要求也变得越来越高;运行循环流化床锅炉的过程中,常会发生水冷壁遭到磨损的问题。分析CFB锅炉水冷壁出现磨损的原因;简要阐述CFB锅炉水冷壁遭到磨损的应对措施,包括调整运行方式,对于来煤质量要加强管理,对于矸石含量要加强控制,以及将防磨带加装于水冷壁当中等。
At present, circulating fluidized bed boilers need to run longer and longer, and wear prevention requirements are getting higher and higher. During the operation of circulating fluidized bed boilers, waterwalls often suffer from wear. Analysis of the reasons for the CFB boiler water wall wear; briefed CFB boiler water wall wear and tear measures, including the adjustment of operation, for the quality of coal to be strengthened management, control of waste rock content to be strengthened, and the installation of wear tape Medium water wall.
