摘要

摘要: 高碳铬铁生产过程会产生CO排放，但当前针对不同炉型和工艺环节的CO排放因子实测数据较为缺乏，制约了铁合金行业排放清单编制和污染减排评估的准确性。为弥补高碳铬铁生产CO排放基础数据不足，研究以内蒙古自治区乌兰察布市4台典型生产设施为对象，涵盖2台半封闭式矿热炉和2台全封闭式矿热炉，采用人工监测与烟气连续排放监测系统（CEMS）相结合的方法，建立CO与NO _x 浓度特征比值关系，结合连续监测数据核算CO排放量和产品排放因子。结果表明：半封闭式矿热炉设施A、B的CO排放因子分别为7.06，3.66 kg/t，全封闭式矿热炉设施C、D配套球团工序的CO排放因子分别为1.41，0.51 kg/t，半封闭式矿热炉排放水平显著高于全封闭式矿热炉。研究可为高碳铬铁行业CO排放核算和分炉型排放因子构建提供实测依据。

Abstract: Carbon monoxide （CO） is emitted during high-carbon ferrochrome production. However， measured CO emission factor data for different furnace types and process stages remain limited， constraining the accuracy of emission inventory compilation and pollution reduction assessments for the ferroalloy industry. To address the lack of basic CO emission data for high-carbon ferrochrome production， this study selected four typical production facilities in Ulanqab， Inner Mongolia Autonomous Region， China， including two semi-closed submerged arc furnaces and two closed submerged arc furnaces. A combined method integrating manual monitoring and continuous emission monitoring system （CEMS） data was applied. A characteristic ratio between CO and NO _x concentrations was established， and continuous monitoring data were used to calculate CO emissions and product-based emission factors. The results indicated that the CO emission factors of semi-closed submerged arc furnace facilities A and B were 7.06 kg/t and 3.66 kg/t， respectively， while those of the associated pelletizing processes of closed submerged arc furnace facilities C and D were 1.41 kg/t and 0.51 kg/t， respectively. The CO emission level of semi-closed submerged arc furnaces was significantly higher than that of closed submerged arc furnaces. This study provides measured evidence for CO emission accounting and the development of furnace-type-specific emission factors in the high-carbon ferrochrome industry.
