浅谈原煤斗蓬煤和给煤机落煤管堵塞原因及防范措施

大唐淮南洛能发电有限公司#6锅炉600MW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。     

Gasifying coal underground

It concludes that although this means of utilising coal is only marginally attractive at present, it could yet prove valuable—especially for exploiting very deep coal seams, as in Belgium—in changing economic circumstances.
