摘要

Gas explosion was a rapid combustion reaction process of flammable gas, and the flame propagates around after ignition. The reaction occurs at the interface between the burned and unburned gases, accompanied by mass and heat transfers. Two prominent characteristics of this process were the sharp increases in the temperature and pressure inside the vessel. Thus, the ultrafine water mist as an inhibitor was adopted to suppress the methane explosion in this study. And the research on gas explosion and its suppression mostly were carried out in a confined space.
