Pulverized Coal Combustion of Nitrogen Free Blast

Abstract. The efficiency of coal combustion is an important factor for the blast furnace process. The influence of low x o /x c on coal combustion performance under nitrogen free blast furnace condition was researched through the self-developed pulverized coal burning device. The results show that the coal combustion rate reduces with x o /x c decreasing, and the combustion rate of bituminous
