| 摘 要： | 首先根据首钢京唐钢铁公司烧结生产数据进行系统的硫平衡计算,分析各种烧结原料对废气中SO2排放量的影响权重,并在此基础上作合理假设,结合国家标准对于不同烧结机SO2排放量的统一计量方法,推导出烧结原料硫含量与SO2排放量判定指标的关系式,建立低硫烧结原料控制标准.首钢京唐钢铁公司烧结生产若要满足500mg.m-3的SO2质量浓度限值,需要将混合料中硫的质量分数降至0.032%以下;若要满足200 mg.m-3的SO2质量浓度限值,需要将混合料硫的质量分数降至0.013%以下,而这在当前的原料条件下是难以实现的.

| Abstract: | Sulfur balance calculations were performed according to production data from Shougang Jingtang Steel Sintering Plant.The impact weight of each sintering material on SO2 concentration in sintering waste gas was analyzed,based on which some reasonable assumptions were made.In combination with the uniform measurement method of SO2 emission concentration for different sintering machines in Chinese standards,a relation formula between sulfur content in the sintering materials and judging index for SO2 emission concentration was deduced and a control criterion for low-sulfur sintering materials was established.If Shougang Jingtang Steel Sintering Plant wants to meet the SO2 emission concentration of 500 mg·m-3,the sulfur content in the sintering mixture need reduce to below 0.032%;if it wants to meet the SO2 emission concentration of 200 mg·m-3,the sulfur content in the sintering mixture need reduce to below 0.013%,but it is very difficult to realize under the current material condition. |
