含煤尘瓦斯爆后气流传播速度的实验研究
Experimental study on flame velocity following explosion of gas containing coal dust
摘要
Abstract
The paper is aimed at an insight into the flame velocity following the explosion of gas containing coal dust.The study is done by performing mixed methane and air explosion experiments and different coal dust mixture experiments using gas-coal dust explosion experiment system;identifying the law how the flame velocity behaves in pipe and manifolds after airflow travels with the flame after explosion;and comparatively analyzing the effect of the coal dust on the flame velocity and its underlying characteristics.The study finds that the coal dust enables a greater flame velocity;the coal dust with a higher volatile matter is more likely to produce a greater air velocity;and the ash has the negative feedback effect on the flame velocity.关键词
