某2500t/d生产线的窑头和窑尾喂煤采用的是KXT(M)科氏力煤粉计量系统。2004年投产以来,运行稳定。但随着使用周期的延长,近年来频繁出现波动窜煤现象,尤其是2014年2月以来更为严重,已影响窑系统的正常操作和煅烧。为此,该公司设备保障部技术人员进行技术攻关,从设备、工艺、电气等多方面进行排查分析,最终找到了影响计量秤稳定运行的“瓶颈”问题,并进行了改造处理。 A 2500t / d production line kiln and kiln tail coal feeding is KXT (M) Coriolis pulverized coal metering system. Since 2004 put into operation, stable operation. However, with the prolongation of the service life, frequent fluctuation of the phenomenon of channeling coal in recent years, especially since February 2014, has affected the normal operation and calcination of the kiln system. To this end, the company’s equipment support department technical staff to conduct technical research, from equipment, technology, electrical and other aspects of the investigation and analysis, and ultimately find a stable operation of the weighing scale “bottleneck ” and carried out the transformation process.
