The composition of sediment inside ash pipe was determinated and analyzed in Nantun coal gangue thermo - power station. in order to remove the sediment, some sediment - removing a-gent. Corrosion inhibitors, acid was applied under control. The practice of ash pipe. cleaning with the thermo - power station operating is successful. 南屯矸石热电厂通过对管道结垢的成分分析,采取添加除垢剂、缓蚀剂、调节酸量,实行不停运酸洗除灰管道实践获得成功。 Based on the character of the fly ash in waste power plant of Taoer Coal Mine ,the comprehensive utilization ways are discussed and the way by which the fly ash is made into cement is mainly analyzed. 结合陶二矿矸石热电厂粉煤灰特性 ,对其综合利用途径作了初步探讨 ,对利用粉煤灰生产水泥这一途径作了分析。 In view of serious erosion incurred by Zhangzhuang Cangue Cogeneration Power Plant's fluidized bed boilers, a technology for casting boiler walls as an entity, as well as that of local mending, by making use of Aluminum Phosphate based refractory cement has been developed. The paper presents an introduction to the production technology of such refractory material, a method of casting and some main hints on maintenance. 针对张庄矸石热电厂流化床锅炉磨蚀严重的状况,研制了一套整体炉墙浇注及局部衬里修补技术———磷酸铝质耐火混凝土浇注法。介绍了这种耐火材料的加工工艺、浇注方法及其养护要点。
