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。 Aiming at the situation that the heating surface of circulating fluidized bed (CFB) boiler is prone to severe wear and tear, frequent maintenance, high energy consumption and high operating cost, supersonic arc spraying method is adopted to treat the heated surface and wear before and after spraying The situation has been compared and analyzed the existing problems. Practice shows that the use of supersonic arc spraying CFB heating surface can effectively extend the service life of the heating surface, reduce unit operating costs and reduce energy consumption caused by frequent start and stop.
