摘要:
瓦斯爆炸是一个瞬间过程。为了分析瓦斯爆炸过程中的爆炸压力以及温度的变化规律,利用封闭的直管瓦斯爆炸实验系统,分别进行了瓦斯体积分数为6.5%~10.0%时的爆炸实验。研究表明:瓦斯的体积分数为9.5%时,管内爆炸温度最高,达到了1 292.27 K;管内达到最高爆炸温度所需要的时间最短,为351 ms;管内爆炸压力最大,达到了0.766 MPa;管内达到最大爆炸压力所需时间最短,用时208 ms。点火源附近的温度都是最高的,管道尾端的温度是最低的。
Abstract:
Gas explosion is an instantaneous process. In order to analyze the rule of explosion pressure and temperature change during gas explosion, the gas explosion experiment with the volume fraction of 6.5% 10.0% was carried out by using a closed straight tube gas explosion experiment system. The results show that when the gas volume fraction is 9.5%, the explosion temperature reaches 1 292.27 K in the tube and the explosion pressure attains 0.766 MPa;mean while the time required to these highest temperature and maximum explosion overpressure shortens to the least, 351 ms and 208ms respectively. Temperature near the ignition source is the highest, and that at the end of the pipeline is the lowest.
