钢铁工业作为重要的SO_2工业排放源之一,其中烧结工序SO_2排放量占到钢铁企业总体排放量的70%以上。自国家《“十一五”规划纲要》将SO_2污染物总量降低10%作为约束性指标以来,钢铁企业大规模开展烧结烟气脱硫工作。“十二五”期间,钢铁烧结烟气脱硫设施的建设步伐不断加快,截至2015年底,安装脱硫设施的钢铁烧结机面积已达13.8万平方米,安装率高达
Steel industry is one of the important sources of industrial SO_2 emissions. SO_2 emissions from sintering processes account for more than 70% of the total emissions of iron and steel enterprises. Since the “Eleventh Five-year” Plan of the State reduces the total amount of SO 2 pollutants by 10% as a binding indicator, the iron and steel enterprises have carried out large-scale sintering flue gas desulphurization work. During the 12th Five-Year Plan period, the pace of construction of steel sinter flue gas desulfurization facilities continued to accelerate. As of the end of 2015, the area of steel sintering machines with desulphurization facilities had reached 138,000 square meters and the installation rate was as high as
