输煤程控系统与筒仓安全监控系统的整合

Integrating the Programmable Control and Silo Security Monitoring in Coal Handling System

储煤是火力发电厂输煤系统工艺流程中一个重要的环节,超大型筒仓是储煤发展的方向,而由于筒仓密封性好,仓内储煤的挥发性气体不易散发,久储极易发热产生自燃甚至爆炸。为了防止事故的发生,设计了筒仓安全监测控制系统,它是输煤系统的一个组成部分。筒仓安全监测控制系统与输煤程控系统相辅相成,在实际生产中的成功应用,对防止储煤筒仓事故,确保实现输煤系统安全、连续、稳定运行具有一定的参考意义。

Coal storage is one of the important elements of coal handling system in fossil-fired power plants,and super-large-scaled silo is the developing trend of coal storage.Due to the airtight performance of the silo,the volatile gases in silo are difficult to be diffused.The spontaneous ignition of the accumulated and heated gases may lead explosion.In order to avoid the accident,the security monitoring and control system has been designed for silos as one of the compositions of coal handling system,integrating the silo security monitoring system and programmable control system in coal handling system is successful application in practical production,which ensures the safety,continuous and stable operation of the coal handling system,and provides worth reference.
