本文用1986年部属17个重点炼铁厂与宝钢炼铁厂的工序能耗指标,从燃料、动力、余热余能回收三个方面进行了详细对比分析。由分析中可看到,因客观条件虽然存在短期赶不上的差距,但能找到从各厂实际出发当前应做好的一些工作,如搞好入炉前原燃料准备、强化热风炉管理,减少环管以下散热损失、减少炉外鼓风损失、合理利用蒸汽、加快陈旧风机更新、推广成熟的余热余能回收技术等并计算了近期可能达到的节能效果。这些工作不仅适用于重点炼铁企业,对地方骨干企业等炼铁厂也适用,而且节能效益更大。 In this paper, the energy consumption indexes of the process of 1986 subordinate 17 key ironworks and Baosteel ironworks are compared in detail from three aspects of fuel, power and residual heat recovery. As can be seen from the analysis, although there are short-term catch-up gaps due to objective conditions, some work that should be done from the actual plant actualities should be found. For example, improving the preparation of raw fuel before entering the furnace, strengthening the management of stoves, The following loss of heat to reduce blast loss outside the furnace, the rational use of steam to speed up the aging fan to promote the promotion of mature technologies such as residual heat recovery and calculate the energy savings that may be achieved in the near future. These efforts are not only applicable to key iron-making enterprises, but also to iron mills such as local backbone enterprises, and their energy-saving benefits are even greater.
