针对顶燃式热风炉,采用送风期冷风流场与燃烧期烟气流场相匹配的技术,提高热风炉格子砖加热面积的利用效率,从而提高热风温度2(20-25℃.该技米已在 12座顶燃式热风炉上投入使用,效果明显,经济效益显著.
For the top-burning hot blast stove, the technique of matching the flow field of the cold air in the air supply period and the flue gas flow in the combustion period is adopted to improve the utilization efficiency of the heating area of the hot-blast furnace lattice brick so as to increase the hot air temperature 2 (20-25 ° C. The technique Rice has been put into use in the 12 top-burning hot stove, the effect is obvious, significant economic benefits.
