粉尘-CO/H2杂混合物爆燃特性研究
Experimental study on deflagration parameters of dust-CO/H2 hybrid mixture
摘要
Abstract
In the present work,we carried out an experimental study of the influence of the coal dust categories,concentration and particle size on the coal dust-CO/H2 hybrid mixture's deflagration characteristics in a semi-open environment.The results indicate that the influence of the dust on the hybrid mixture's deflagration is mainly the outcome of the competitive relation between two opposite effects,the heat absorption for volatile releasing and the reaction of the released volatile.For the high volatile coal dust,the deflagration reaction of the released volatile dominates,which makes the deflagration severity gradually rise with the rising of the volatile content;while for the low volatile coal dust,the heat absorption for the volatile dominates,which reduces the deflagration severity.For bitumite like the Yinbei coal,with the increase of the dust concentration,the deflagration severity varies with a U-shaped tendency,while for the coke dust with a low volatile content,the change of the deflagration severity with the dust concentration is not obvious.关键词
