锅炉原煤斗蓬煤和落煤管堵塞原因及改造措施

Reason and Preventive Measures of Coal Boiler Coal Cloak and Coal Drop Pipe Blockage

在阐述了大唐淮南洛能发电有限公司6号600 MW锅炉机组多年以来原煤斗蓬煤、落煤管堵塞现象经常发生,尤其在汛期雨大时问题更为明显,掺烧褐煤及煤泥后由于燃煤水分增多,棚煤现象更为突出。原煤斗蓬煤、落煤管堵塞,严重影响了机组的正常发电,同时由于棚煤时被迫投入大油枪助燃,直接造成发电成本提高的情况后,详细讨论和介绍了相应的改造方案及实施情况。

Over many years row coal coal cloak,coal drop pipe blockage phenomena often occurs in Datang Huainan Power Company Limited.#6 boiler 600 MW units,especially in the flood season rain when the problem becomes more apparent,mixedly burning brown coal and slime because of coal moisture increased,shed coal phenomenon is more outstanding.Raw coal coal cloak and coal drop pipe blockage seriously affecting the normal power generation unit,at the same time,as the studio forced into big gun when the coal combustion,caused directly by generating cost improve,the paper discusses in detail and introduced the corresponding retrofit scheme and implementation.
