高炉风口回旋区工作状态监控技术的研究现状

在高炉生产过程中,只有从风口窥视孔可以直接观察高炉内的情况,操作者十分关注高炉风口区的工作状况,并将其作为判断和控制高炉操作的重要依据之一.风口前的监测可以获得喷煤高炉在风口处煤粉输送情况,还可以根据风口亮度与煤粉燃烧数值模拟结合,研判煤粉在风口回旋区的燃烧状况及温度分布等.简述了国内外在高炉风口回旋区温度检测、工作状态的监控技术的研究现状,提出利用数字图像处理技术与数值模拟结合,解决高炉风口回旋区工作状况监测和控制的思考.

Recent Research on Supervision Running State of the Tuyere and Raceway in Blast Furnace

The manipulators pay fully attention to the running state of raceway looked into tuyere peehole in blast furnace in its production process. And it is important for judgement and control the blast furnace. The pulverized coal feeding and burning cases can be supervised by peehole in tuyere. Temperature distribution can be studied by brightness and numerical simulation of pulverized coal combustion. The recent research of temperature examined and supervision technique of the tuyere and raceway in blast furnace are set forth at home and abroad. A method settling supervision and control the state of tuyere and raceway in blast furnace is put forward by coalescent numeric image process technique to numeric simulate two dimensional imaging technique.
