摘要水泥窑系统中的硫主要来源于原煤燃料及石灰质、铁质等生料配料。通过总结生产经验数据，形成了脱硫设备前硫排放量理论经验公式，并根据理论计算结果，预先采取硫排放量控制措施，调整配料方案，控制入窑硫化物总量。同时，借助XRD检测仪器探究了原料中黄铁矿含量对硫排放量的影响，定性定量分析结果显示，原料中全硫含量相同时，黄铁矿含量越低，窑尾硫排放浓度越低，二者呈正相关。

Abstract: The sulfur in the cement kiln system mainly comes from raw coal fuel and raw materials such as limestone and iron. By summarizing production experience data, a theoretical empirical formula for sulfur emission before desulfurization equipment has been formed. Based on the theoretical calculation results, sulfur emission control measures have been taken in advance, and ingredient plans have been adjusted to control the total amount of sulfur entering the kiln. At the same time, the influence of pyrite content in raw materials on sulfur emissions was explored using XRD detection instruments. Qualitative and quantitative analysis results showed that when the total sulfur content in raw materials was the same, the lower the pyrite content, the lower the sulfur emission concentration at the preheater, and the two were positively correlated.

Key words: sulfur emissions empirical formula XRD detection pyrite
