Dust Explosion Sensitivity Tests on M-1, M-30,Composition B,and HMX.

摘要

An experimental program has been conducted to establish the dust explosion sensitivity of M-1, M-30,Composition B and HMX as a function of particle size,dust cloud concentration,and relative humidity. Values of minimum concentration for explosion,minimum ignition energy and minimum ignition temperature have been determined under ambient conditions for three particle sizes. In addition,the effects of relative humidity and concentration on ignition energy have been observed. It has been found that the order of decreasing sensitivity of these materials is as follows: M-1, M-30,Composition B and HMX. The minimum ignition energy was found to increase with increasing particle size,test chamber relative humidity and decreasing dust cloud concentration. Minimum ignition temperature increased with increasing particle size. (Author)
