水冷壁是锅炉的最上型的受压部件,锅炉中有40%~50%甚至更多的热量被水壁吸收,如果使用司防护不当,则极易造成水冷壁管在运行中爆裂,导致管内的水大量泄出进入炉膛,锅炉无法继续运行而停炉。较为详细地对爆管原因进行分析,并针对多种爆管现象采取不同的处理方法进行介绍,取得了较好的效果。 Water wall is the most pressure-type components of the boiler, the boiler has 40% to 50% or more of the heat absorbed by the water wall, if the Secretary of improper protection, it is likely to cause the water wall tube burst in operation, resulting in the tube Large amount of water leaked into the furnace, the boiler can not continue to run and shutdown furnace. The reason of explosion is analyzed in detail, and different treatment methods are introduced according to the phenomenon of multiple squibs, and good results have been achieved.
