Abstract

Abstract

Aluminum dust explosion experiments have been carried out in the rectangular pipe dust explosion device to study on the effects of the ignition delay time, the dust particle size, and the dust concentration on the maximum explosion pressure as well as the maximum rise rate of explosion pressure. Experimental results show that all three parameters affect significantly the explosive pressure of aluminum dust. The maximum explosion pressure and the maximum explosion pressure first increase and then decrease with the increasing ignition delay time or the decreasing size of the aluminum powder. The rising rates of both the maximum explosive pressure and the maximum explosion pressure increase and then decrease as the aluminum concentration increases, indicating that a certain concentration exists which could lead to the largest explosive power.
- aluminum dust explosion,
- ignition delay time,
- particle size,
