清河发电公司试燃用蒙东褐煤的措施与实践

Measures and Practice of Qinghe Power Generation Company Conducted the Test of Burning the East Mongolia Lignite

文章指出了燃烧蒙东褐煤的背景,即煤炭资源供应紧张使企业不得不选择试烧蒙东褐煤。蒙东褐煤水分大、易自燃,属于危险性最大的煤种。因此中国电力投资集团公司清河发电公司选择了3、4号锅炉进行蒙东褐煤燃烧试验。该试验取得了成功,文中对试验中采取的措施、实践手段等进行了详细叙述,如高峰时减少褐煤掺烧比例,改造磨煤机叶轮等,具有一定的参考价值,并为今后全面燃用蒙东褐煤积累了经验。

This paper indicated the background of burning East Mongolia lignite.i.e.,the rathe short supply of coal made the enter prise to have to curry out the trial burning of East Mongolia lignite.East Mongolia lignite features high moisture,easy to spontanesusly buming, belonging to the most dangerous coal rank.consequenlly China Power Investment Group Corporation Qinghe Power Generation Company Chose NO.3＆4 boilers to conduct the tests of burning East Mongolia lignite,the tests came off all right.The paper detailed the taken measures and practice means,such as,to reduce the blended proportion of lignite at peak time,to retrofit the impellers of pulverizers and so on.These measwres and means have a certain reference valne and have accumulated experiences for completely burning East Mongolia lignite in the future.
