循环流化床锅炉水冷壁磨损原因分析

Cause Analysis ofWater WallWear of Circulating Fluidized Bed Boiler

CFB锅炉通常是指在同一台流化床锅炉中功率更大、燃料适应性更广的锅炉,在其实际应用工作环节中同样也还存在的一系列质量问题,如水冷壁管极易磨损,连续运行周期短,易发生爆管事故。因此,迫切需要探索一套适用于CFB锅炉磨损防护的方法,对循环流化床锅炉水冷壁在实际使用中易磨损的问题进行了深入分析,列出了易磨损部位及主要原因。

CFB boiler usually refers to the boiler with higher power and wider fuel adaptability in the same fluidized bed boiler.However,there are also a series of quality problems in its practical application.For example,the water wall tube is very easy to wear,the continuous operation cycle is short,and the tube explosion accident is easy to occur.Therefore,it is urgent to explore a set of methods suitable for CFB boiler wear protection.The problem of easy wear of circulating fluidized bed boiler water wall in practical use is deeply analyzed,and the easy wear parts and main reasons are listed.
