前言高炉喷吹煤粉是继精料后又一项大幅度降低焦比、节约能源的有效措施。我厂地处蕴藏丰富无烟煤的湘中地带,无焦化设施,完全靠外购焦炭生产。因此,如何较好地采用喷煤技术,实现以煤代焦就具有很大的现实意义和经济效益。1965年我厂开始进行喷煤研究试验,1972年着手喷煤工艺设计。由于当时的指导思想和对喷煤工艺的认识不足,整个喷煤系统直到1979年仍处于不正常状态,喷煤量少,效果不显著,生产环境恶劣。1980年以
Preface Pulverized coal injection pulverized coal injection is another effective measure to greatly reduce the coke ratio and save energy. Our factory is located in the Xiangzhong area rich in anthracite, no coking facilities, entirely by the purchase of coke production. Therefore, how to adopt the coal injection technology well and achieve coal coke substitution has great practical significance and economic benefits. In 1965, our factory began to carry out the coal injection research experiment. In 1972, we began to design the coal injection process. Due to the guiding ideology of the time and the lack of understanding of the coal injection process, the entire coal injection system was still in an abnormal state until 1979, with little coal injection, insignificant effect and poor production environment. 1980 years
