Low nitrogen combustion furna

The efficiency of coal combustion is an important factor for the blast furnace process. The influence of low xo/xc 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 xo/xc decreasing, and the combustion rate of bituminous coal is higher
