摘　　要：烧结是钢铁冶炼中的一个重要环节,在烧结过程中将产生大量烟气,据统计,每生产1 t烧结矿大约产生4 000～6 000 m3的烟气,其携带粉尘量较大,一般含尘量为0.5～15 g/m3,且含有部分腐蚀性气体,如SOx,NOx等酸性气态污染物,它们遇水后将形成稀酸,造成大气污染和金属部件持续腐蚀.随着国家环保政策的日益严格,充分研究烧结烟气特点,从而对其进行综合处理以达到国家排放标准逐渐成为各个钢铁厂迫在眉睫的任务.详细探讨了烧结烟气的产生及特点,并就烧结烟气综合处理技术提出了一些建议,供各钢铁厂参考.Sintering is an important part in the enterprise of steel-making. A large amounts of fuel gas will be produced in the process of sintering. It is estimated about 4 000-6 000 m3 amounts of fuel gas with the dust of 0.5 -15 g/m3 and corrosive gas such as SOx, NOx will be produced in the producing process of one ton of sinter. The corrosive gas of SOx, NOx will be converted into thin sour after mixing with water, which will cause atmosphere pollution and metal corrosion. It is an urgent task for each enterprise of steel-making to deal with sintering fuel gas synthetically by studying fully the characteristics of sintering fuel gas because of more strict enviromnental policies. Some advices were put forward about the synthetical technologies of dealing with sintering fuel gas, providing references for the steel-making enterprises.
