煤质监测中煤中全硫含量的分析

Analysis of the Total Sulfur Content in Coal in Coal Quality Monitoring

该文分析了大气污染物二氧化硫的危害,其与含硫煤的关系,阐述了煤炭脱硫的重要性与国内常见的煤炭脱硫方法,通过煤质监测工作抽测大连市47家用煤单位,利用库仑滴定法对煤中全硫含量进行测定,并对测定数据进行分析。结果显示:47家用煤单位煤中全硫含量监测结果全部达标,超标率为0,证明大连市市场上目前所使用的煤炭,经过脱硫后煤中硫含量得到了有效控制,降低了二氧化硫对大气污染的影响,为推动城市空气质量大幅度改善做出了贡献。

This paper analyzes the harm of sulfur dioxide,the atmospheric pollutant,and its relationship with sulfur-containing coal,and expounds the importance of coal desulfurization and the common methods of coal desulfurization in China.This paper samples 47 coal-burning units in Dalian through coal quality monitoring,uses coulometric titration to determine the total sulfur content in coal,and analyzes measured data.The results show that the monitoring results of the total sulfur content in coal in 47 coal-burning units all reaches the standard,and the rate of exceeding the standard is 0,which proves that the sulfur content in coal currently used in the Dalian market has been effectively controlled after desulfurization,reduces the impact of sulfur dioxide on air pollution,and makes contributions to promoting the substantial improvement of urban air quality.
