摘要
在镜下对 40 6 3m3高炉回旋区残炭的研究表明 ,不同煤岩显微组分所形成的残炭性状不同 ,这些残炭在镜下各有其特征 :喷煤水平在 16 1- 2 14kg/t间 ,随着喷吹量提高 ,回旋区中残炭虽增加 ,但未见堆积 ;未燃残炭绝大部分随上升气流经高炉被消耗掉 ;高炉炉顶逸出粉尘中残炭极少 ,且未发现由烟煤镜质组衍生的残炭 ,由无烟煤和烟煤丝质组衍生的残炭也很少。
The chars are sampled from the raceway of 4063 m 3 BF Main conclusion from the research is as follows:the chars of various characteristics from different macerals have been studied under microscope,within the PCI range of 161 214 kg/t,the char amount is increased with the injection rate,but no pile of char has been found in raceway Most of unburned char is brought by steam up to BF and consumed No char from the vitrinite of bitumimuns coal has been found in dust from the top of BF,the amount of the char from the anthracite and the fusinite of butiminous coal is only a little
