摘要
为了梳理点火源对瓦斯爆炸特性的影响规律,通过文献调研的方法,对点火能量、点火方式、点火位置3个方面的国内外研究现状进行了综合评述,并对研究方法和结论进行提炼。得出点火源对瓦斯爆炸的影响研究集中在3个方面,爆炸压力、爆炸火焰以及爆炸极限,点火方式的研究主要为电点火,点火位置的研究较为多变。同时针对目前研究所取得的成果和存在的不足,对未来研究方向做出了合理的展望。
In order to sort out the influence law of ignition source on gas explosion characteristics,a comprehensive review was made on the domestic and international research status of the three aspects of ignition energy,ignition mode and ignition position through literature survey methods,and the research methods and conclusions were refined.It was concluded that the research on the influence of ignition energy on gas explosion focuses on three aspects,explosion pressure,explosion flame and explosion limit;the research on ignition mode was mainly electric ignition;the research of ignition position was more variable.At the same time,according to the current research achievements and shortcomings,a reasonable outlook for the future research direction was made.
