Abstract:
This work investigated the influence of particle-injection pressure and ignition delay on explosion parameters of methane–coal particle mixture using a 20-L sphere. Results indicated that the maximal explosion pressure Pmax and the maximal pressure rise rate (dP/dt)max tended to first increase and then decrease, with ignition delay increasing as the particle-injection pressure ranged from 1.2 to 2.4 MPa, attaining their maximum values at different moments. However, as the particle-injection pres...     »
