摘　　要：干熄焦装置常用放散烟气中含有一定量的CO及SO2,直接外排会造成环境“碳”污染和“硫”污染,必须净化处理后达标排放。通过理论计算,从焦炉加热燃烧过程中空气消耗量、氧气体积分数和燃烧煤气体积分数的变化情况进行分析,探讨了干熄焦装置常用放散烟气回配焦炉加热燃烧的可行性。初步理论分析表明,回配方案可行。The common flue gas from coke dry quenching plant contained certain amount of CO and SO2,its direct discharge would cause"carbon"and"sulfur"pollution in the environment,so it must be purified and treated beforehand to meet the emission standards.Through the theoretical calculation,the feasibility of recycling the commonly discharged flue gas from the CDQ plant to the coke oven for heating and combustion was explored by analyzing the changes of air consumption,oxygen volume fraction and gas combustion volume fraction in the process of coke oven heating and combustion.And the preliminary theoretical analysis showed that the recycling scheme was feasible.
