摘　　要：在“双碳”目标的背景下,结合国内能源应用现状,采用煤层气喷吹替代部分固体燃料用于烧结生产,开发适宜的喷吹装备,不仅能改善烧结矿质量,还可以有效实现烧结生产的减排和降本。根据富氢烧结技术原理并结合现场情况,确定了喷吹装备的设计参数并进行了工业化试验,分析了煤层气喷吹对烧结产量、质量以及能耗指标的影响。研究表明:在吨矿喷吹量为0.48 m^(3)/t时,烧结矿产量变化不大,粒径与强度明显提高,固体燃料消耗减少了2.44 kg/t,CO_(2)减排量能达到6.04 kg/t,生产成本可降低2.34元/t。Under the background of the“double carbon”target,combined with the current situation of domestic energy,the coalbed methane injection is used to replace part of the solid fuel for sintering production,and the development of a suitable injection equipment can not only improve the quality of sinter,but also effectively realize the emission reduction and cost reduction of sintering production.In this paper,according to the H 2-rich sintering technology principle and combined with the field situation,the parameters of injection equipment were determined,and the industrial test was carried out.The influence of coalbed methane injection on sintering production,quality and energy consumption was analyzed.The research shows that when the injection rate is 0.48 m^(3)/t,the yield changes little,the particle size and strength are obviously improved,the solid fuel consumption is reduced by 2.44 kg/t,the CO_(2) emission reduction can reach 6.04 kg/t,and the production cost can be reduced by 2.34￥/t.
