大型钢铁联合企业采用高炉-转炉长流程钢铁生产过程产生大量的余热余能资源,具有巨大的回收利用潜力.系统分析了典型钢铁流程的能量流和具备回收利用价值的主要余热余能资源情况,提出了采用当前先进的工艺技术进行回收发电.通过建立分布式电站,使得钢铁企业余热余能就近回收、就近输送、就近使用,从而实现钢铁企业用电基本自给.研究结果表明:基于一个年产1 000万t规模的大型钢铁联合企业,采用分布式发电方式回收该钢铁生产流程的余热余能资源,其发电量可达到41.95亿kW·h,折合吨钢419.5kW·h.钢铁企业通过余热余能回收发电完全可以做到用电基本自给,甚至完全自给,乃至外供.
Owing to the typical BF-BOF process in an integrated iron and steel enterprise, it produces large plenty of residual heat and energy, which has great potential for recovery. The energy flow as well as the recoverable residual heat and energy resource in a typical iron and steel manufacture process, had been systematically analyzed. It sug-gests that the residual heat and energy can be recovered as electric power by using present advanced process technol-ogy. By building the distributed power generation, the residual heat and energy can be recovered, transported, and reused as close as possible, and so as to make the electric power sell-support in iron and steel enterprise. Based on an integrated steel plant of 10 million tons per year in capacity, the residual heat and energy can be recovered by dis-tributed generation system, and the power generation capacity can reach to 4195000 MW · h with the average of 419.5 kW· h per ton steel. It can be concluded that the electric power sell-support or even outer supply in iron and steel enterprise can be completely realized through the residual heat and energy recovered by distributed power gen-eration.
