摘要
针对循环流化床(CFB)锅炉受热面易严重磨损、检修频繁、启动能耗和运行成本高的情况,采用超音速电弧喷涂的方法,对受热面进行防磨处理,并对喷涂前后的使用状况进行了对比,分析了存在的问题。实践表明,CFB受热面采用超音速电弧喷涂后可以有效延长受热面使用寿命,降低机组运行成本,减少频繁启停而引起的能源消耗。
Under the circumstance of the Circulating Fluidized Bed (CFB) boiler heating surface worn away seriously ,repair frequently and high costs for operation and starting energy, adopting transonic electric arc spraying method to prevent the heating surface been abrasived.contrasted the condition of front and back spraying;analyzed the existent problem.
