火力发电厂封闭式圆形贮煤场安全动态监测系统研究

Study on safety dynamic monitoring system of closed circle coal storage in thermal power plan

本系统从煤堆表面温度、挡煤墙附近燃煤温度、可燃气体烟雾浓度、入场明火煤温度等几方面进行安全监测。分析了安全监测原因和各个监测系统所完成的功能,并针对具体的工程说明了安全监测系统的构成及监测设备工艺布置的具体方案。系统具有在线实时监测、安装方便等特点,切实保障人员人生安全。

The safety monitoring is carried out from the surface temperature of the coal pile,the coal temperature near the coal wall,the concentration of the combustible gas and the smoke,and the temperature of the open flame coal into the coal storage.The reasons for the safety monitoring and the functions of the various monitoring system are analyzed.For the specific project the composition of the safety monitoring system and the specific process layout of the monitoring equipment are described.The system has the characteristics of online real-time monitoring,and easy installation,and effectively protects the safety of personnel.
