摘　　要：选择性烧结废气循环(SWGR)是普锐特冶金技术公司开发的一项节能减排技术。它可将最多50%的烧结废气循环用于烧结工艺中,从而显著降低烧结和下游脱硫、脱氮的运行成本。世界各地已有多套SWGR系统建成运行。分析了废气温度和废气成分沿烧结机长度方向的分布特点对SWGR系统的影响。介绍了山钢集团根据企业的具体情况采用第1+3段循环模式的SWGR系统的特点及生产运行状况。进一步验证了SWGR是一种节能减排效果极佳的环保型方案,能灵活满足客户需求和国家相关规定。Selective Waste Gas Recirculation (SWGR) is a energy saving and emission reduction technique developed by Primetals Technologies. It is designed to recirculate up to 50% of the sinter waste gas to the sinter strand and thereby generate huge savings for operating costs of sintering and downstream DeSOx/DeNOx. Numerous SWGR reference plants are in operation worldwide. The influence of distribution characteristics of waste gas temperature and waste gas composition along the length direction of sinter on SWGR system was analyzed. The characteristics and operation status of SWGR system with cycle mode 1+3 adopted by Shansteel Group according to the specific conditions of the enterprise are introduced. It further proves that SWGR is an environmental protection scheme with excellent energy saving and emission reduction effect, which can flexibly meet customer needs and relevant national regulations.
