基于改进程序升温装置的煤自燃过程中H2的生成规律
Pattern of H2 generation during coal spontaneous combustion based on improved temperature-programmed apparatus
摘要
Abstract
This paper is intended to investigate the role of H2 as an indicator gas in spontaneous com-bustion prediction based on the insight that coal spontaneous combustion is one of the major threats in coal mine disasters.By taking the candle coal from Dongrong No.2 Coal Mine in Shuangyashan,the co-king coal from Jixi Ronghua Coal Mine,and the gas coal from Hegang Junde Coal Mine as the research subjects,the study conducts the experiments on three coal samples by using an improved temperature-programmed apparatus to analyze the synergy between the generation patterns of H2 and other gases,as well as the relationship between H2 and coal temperature and coal type.The results show that during the temperature increase process,the pyrolysis and gasification reactions of the coal samples lead to the re-lease of H2,with the release rate increasing significantly as the temperature rises.Different coal types ex-hibit different H2 generation characteristics.H2 demonstrates good sensitivity and response speed,show-ing potential as an indicator gas for coal spontaneous combustion.This study reveals the patterns of H2 generation during the coal spontaneous combustion process,providing a reference for the combined use of H2 and other gases in predicting coal spontaneous combustion.关键词
