我公司所用煤粉计量为合肥水泥研究设计院的科氏力秤,下煤一直不太稳定,时有冲煤和断煤现象发生,严重时尾煤秤停机后仍一直冲煤,使分解炉出口温度达到满量程,只能采取停尾煤罗茨风机的紧急措施。仓底闸板开度一直不能超过50%,冲煤严重时随时可能将秤体压死。不仅影响熟料质量和增加煤耗,也使预热器系统存在极大的安全隐患。针对此种状况,我们利用停机对煤粉秤系统进行全面检查。 The pulverized coal used by our company is the Coriolis scale of Hefei Cement Research and Design Institute. The coal has not been stable for a long time. When the coal fines and the coal off occur, Export temperature reaches full scale, can only take a tail stop coal Roots blower emergency measures. Barrage at the end of the opening can not exceed 50% of the coal may be severely punched when the scale body can be crushed at any time. Not only affect the clinker quality and increase coal consumption, but also make the preheater system has great potential safety problems. In view of this situation, we use the shutdown of coal weighing system to conduct a comprehensive inspection.
