摘要
通过对主要工业粉尘爆炸压力测定,发现粉尘爆炸下限与测试用点火具压力和燃烧持续时间有关。对于不同的粉尘,通过燃烧时间来判断爆炸下限对于工业粉尘防爆设计具有实际意义。
By testing of explosible pressure of aluminium and coal dusts, it is found that the lower explosible limit of dust clouds has some relations with the characteristic of chemical ignitor and duration time of pressure-time curve for different dusts. The maximum duration time is coincided with the lower explosible limit made by IEC standard.
