3~#炉投产后,炉顶、炉墙漏烟、漏灰现象严重,成了影响我厂3~#机组安全、稳定、经济运行的关键,笔者认为造成这种局面的原因有设计上的,有安装上的,也有运行上的。1 3~#炉炉顶、炉墙漏烟、漏灰原因 (1)我国电站锅炉结构设计中,一般不考虑前、后、左、右膨胀,而只考虑垂直方向的上下膨胀。3~#炉系八十年代末制造的670t/h锅炉,同样避免不了这个问题。因此锅炉投运后密封部位必然出现因膨胀受阻而
3 ~ # furnace put into operation, the top of the furnace wall, smoke, the phenomenon of serious leakage of ash, has become the impact of our plant 3 ~ # unit safety, stability, economic operation of the key, I believe that the reasons for this design have the design , There are installation, but also on the operation. 1 3 ~ # furnace roof, furnace wall leakage, the reasons for leakage of ash (1) China’s power plant boiler structure design, generally do not consider before and after the left and right expansion, but only consider the vertical expansion of the upper and lower. 3 ~ # furnace The late 1980s 670t / h boiler, the same can not be avoided this problem. Therefore, after the operation of the boiler put into operation must be blocked due to expansion of blocked parts
