浅谈劣质石煤工业分析方法与发热量测定的注意事项

摘要

介绍了湖南省会同县＂鲁冲－铁溪＂矿区土洞井田煤矿中的劣质石煤性质，结合煤质工业分析方法和发热量测定相关国家标准的规定，提出了在对劣质石煤进行水分、灰分、挥发分及发热量测定时需注意的方法要点。特别是针对劣质石煤的高灰分、低挥发分以及低发热量的这些特点，归纳和总结了在相关试验过程中容易出现的问题和忽略的细节，并提出了相应的解决方法，从而确保了劣质石煤的工业分析和发热量测定的准确性，为工业生产和锅炉燃烧提供准确的参考数据。%This paper introduces the properties of inferior coal in Huitong County of Hunan Province "Lu Chong-Tie Xi"mine soil hole mine in coal mine , combined with the analysis method and calorific value determination of relevant national standard of coal industry , puts forward the method of water , points to inferior coal ash , volatile matter and heat capacity determination should note .Especially the characteristics of the inferior coal , high ash content , low volatile and low heat generation , and summarized the easily occurred in the test process and ignore the details , and put forward the corresponding solution , so as to ensure the accuracy of the analysis and determination of calorific value of inferior coal industry , to provide reference data accurate for industrial production and boiler combustion .
