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.
First of all, based on the sintering production data of Shougang Jingtang Iron and Steel Company, the sulfur balance of the system was calculated. The influence of various raw materials on the SO2 emission in exhaust gas was analyzed. Based on this, reasonable assumptions were made and the SO2 emission of different sintering machines Volume of the unified measurement method to derive the sulfur content of sinter raw material and SO2 emissions determination index of the relationship between the establishment of low-sulfur sintering raw material control standards. Shougang Jingtang Iron and Steel Company to meet the sintering production of SO2 500mg.m-3 concentration limits Value, it is necessary to reduce the mass fraction of sulfur in the mixture below 0.032%; to meet the SO2 concentration limit of 200 mg.m-3, the mass fraction of sulfur in the mixture needs to be reduced below 0.013% The current raw material conditions are difficult to achieve.
