【摘要】 用红外线热象仪研究了喷煤高炉风口回旋区温度分布。喷煤时煤粉出口温度较回旋区断面平均温度低７００℃左右。富氧使回旋区温度升高。ＣＣＤ技术的发展，使风口区的监测与自动控制喷煤量在实际高炉中得以应用。更多还原

【Abstract】 Temperature distribution of blast furnace raceway was measured and studied with an infra-red thermal image system.During coal injecting,the temperature at the pulverized coal outlet is about 700℃lower than the average temperature of the raceway cross section.Oxygen enrichment of hot blast increases the temperature of the raceway.The development of CCD(Charger Coupled Devices) technology makes the supervision of the raceway and automatic adjustment of pulverized coal injection into practice.更多还原
