| 摘 要： | 对风口回旋区内煤粉燃烧火焰断面温度场分布进行数值化研究,有助于诊断高炉风口回旋区煤粉的燃烧状态和了解炉缸的工作状况,同时可以指导改进氧煤燃烧器,改善氧煤燃烧工艺和高炉喷煤操作.采用非接触辐射测温理论和技术,建立了高炉风口回旋区断面图像的二基色(RG)信息与温度间的关系模型,进行了二维平面投影火焰温度场测量,并绘制了回旋区断面温度场等高线.试验结果表明:这种测温技术可行,与抽气式热电偶测量结果相比,准确度达98.09%.

| Abstract: | It is useful for diagnosing coal combustion status and the tuyere and raceway in blast furnace, at the same time, it is supervision running state to study on temperature-field of also helpful for supervising the structure of oxygen and coal burning apparatus, improving coal combustion technology and coal injection operation. The model between red and green information of true color flame image and temperature is established and two dimension raceway section projection temperature-field are achieved by applying no-touch radiation temperature measurement theory and technology. It is proved with experimentation that the method is effective and feasible, and the testing precision can reach 98.09% compared to the testing result of thermocouple of taking out gas. |
