摘要
采用大管状煤尘爆炸仪考查了不同工业分析指标与煤尘爆炸火焰长度的关系,实验结果表明,挥发分是影响煤尘爆炸性的主要因素,总体上呈现出挥发分越大,灰分越小,煤尘爆炸火焰长度越大的趋势.实验结果为通过煤的工业分析数据初步判断煤尘的爆炸性提供了基础依据.
Abstract
Relationship between different industrial analysis indexes and the flame length of coal dust explosion is examined by using a large tube coal dust explosion instrument.The experimental results show that volatile content is the main factor affecting coal dust explosion.In general,the flame length of coal dust explosion shows a trend of increasing with the increase of volatile content and the decrease of ash content.The results provide the basis for preliminary judgment of coal dust explosibility through industrial analysis data of coal.
