摘要 硫分和灰分是煤炭中两项重要的技术指标,在煤炭中含量较高,煤炭在燃烧、气化和热解过程中,释放出大量的粉尘和二氧化硫,在全球气候变化中发挥着重要作用。依据GB/T 214—2007和GB/T 212—2017分别对337批次煤样中的全硫含量和灰分进行测定分析。通过对结果数据的汇总统计分析:天水市域内全硫含量分布区间为0.10%~1.22%,同时不同煤炭中硫分含量差异较大,无烟煤的硫分明显低于烟煤;灰分含量分布区间为2.32%~22.24%。 Sulfur and ash are two important technical indicators in coal.And there have high content in coal.Coal releases a large amount of dust and sulfur dioxide in the process of combustion,gasification and pyrolysis,which plays an important role in global climate change.In this paper,the sulfur content and ash content in 337 batches of coal samples were determined and analyzed according to GB/T 214-2007 and GB/T 212-2017.Through the summary and statistical analysis of the result data,the distribution range of sulfur content in Tianshui city is 0.10%~1.22%.At the same time,the sulfur of anthracite is significantly lower than that of bituminous coal;The distribution range of ash content is 2.32%~22.24%.
