小氮肥厂使用的φ2260及φ1980煤气发生炉,其炉口密封原设计是使用石棉盘根填料密封,由于该处直接与火焰接触,温度很高,同时灰尘、煤颗粒也大量存在,因而石棉盘根很难对付。

小氮肥厂使用的φ2260及φ1980煤气发生炉,其炉口密封原设计是使用石棉盘根填料密封,由于该处直接与火焰接触,温度很高,同时灰尘、煤颗粒也大量存在,因而石棉盘根很难对付。根据我厂的使用情况,换上一组新填料使用不到3-4天就坏了,甚至有时刚换上
Small nitrogen fertilizer plant φ2260 and φ1980 gas furnace, the furnace mouth seal design is the use of asbestos packing packing seal, because the Department in direct contact with the flame, the temperature is high, while dust, coal particles also exist in large numbers, and asbestos plate Root is hard to deal with. According to the use of our factory, put on a new pack of less than 3-4 days to use the bad, or even just replaced
