二,循环流化床锅炉内衬不同部位暴露出来的问题和解决的可能性循环流化床锅炉内衬会在多处部位发生损毁, 尤其在调试投运过程中,当运行还不稳定时更容易发生。1.损毁部位及现象损毁发生率最多的部位和现象有:(1)落煤口下端和出口下部炉膛部分以及周围二次风口区炉衬, 被挖损吃透造成露管爆管的问题。(2)返料斜管下斜面和出口下部炉膛转角炉衬,被挖损出深坑;(3) 炉膛后上部烟气出口与旋风筒烟气入口之间的水平
Second, the circulating fluidized bed boiler lining different parts exposed problems and the possibility of CFB boiler lining will be damaged in many parts, especially in the commissioning and commissioning process, when the operation is not stable even more Easy to happen. 1. The damaged parts and phenomenon of the most damaged parts and phenomena are: (1) the lower end of the coal outlet and the lower part of the outlet furnace and the surrounding secondary outlet area lining, was digging through the exposed tube burst pipe problems. (2) the lower slope of the reheat inclined tube and the lower furnace corner lining at the outlet are dug out of the deep pit; (3) the level between the upper flue gas outlet after the furnace and the inlet of the cyclone flue gas
