利用安装在喷煤支管上的测温元件连续测量管道内煤粉流股的温度 ,通过计算机采集、记录和处理测温数据 ,对支管堵塞、停煤、断煤及输煤不畅等喷吹故障进行在线监测和报警 ,也可根据温度—时间推移图了解各支管过去一周的喷吹状况。针对多管路喷煤系统设计的 30测点单支管喷吹状态监测系统已在首钢 1号高炉喷煤站投入应用。
The temperature of the pulverized coal stream in the pipeline is continuously measured by the temperature measuring element installed on the coal injection branch pipe, the temperature measurement data are collected, recorded and processed by the computer, and the blockage of the branch pipe, coal-cutting, coal-cutting, Fault online monitoring and alarm, but also based on the temperature - time chart to understand the branch over the past week’s injection situation. The 30-point single-pipe injection status monitoring system designed for multi-line coal injection system has been put into operation at Shougang No.1 blast furnace PCI station.
