Experimental investigation of external explosion in the venting process

摘要

Experimental investigations were conducted on the process of combustion and explosion vent in a 200 mm (diameter) X 400 mm (length) vertical cylindrical vessel. When CH_4-air mixture gases were used and the vent diameter was 55 mm, conditions of PHI (equivalent ratio)=0.8, PHI=1.0 and PHI=1.3 and two ignition positions (at the cylinder center and bottom) were selected. The venting processes and the correlated factors are discussed in this paper.
