摘要
Abstract
This paper analyzes misunderstandings in explosion parameter of pulverized coal from the theoretical and practical aspects as the domestic norms introducing ВТИ.Through comparative analysis of various domestic and foreign literatures,the following three basic issues are explored.①Selection of explosion parameter determination method.②Explosion parameter classification definition standard and grade selection.③Selection of explosion-proof countermeasures matching with explosion parameter grade.Based on the exploration results,the misunderstanding that should be clarified is pointed out.It is the first to propose the precise and simplified calculation method which can replace ВТИ standard or Russian 2000 standard.The relationship between the explosion parameter grade of pulverized coal and the explosion-proof temperature of coal mill is analyzed.The pulverized coal explosion qualitative index-explosion-proof temperature line diagram is proposed to qualitatively analyze the optimization route in explosion—proof coal blending operation.关键词
