The experimental study of type K or S condensed aerosol on inhibition of gas explosion
As one of the main disasters in mine explosion, gas explosion is a chain chemical fast-reaction. Combustion chain reaction is inhibited by gas explosion suppression technique, which controls the explosive development and reduces the damage of explosion artificially. Based on the experimental research, the study compared and analysed the type K. and S condensed aerosol s impact on the explosive limits of methane concentration and the critical oxygen concentration of methane explosion. The results show that with the increase of aerosol concentration, the methane explosion limits is decreased. Different concentrations or types of aerosol have different effects on methane explosion. When the concentration of S aerosol is 315mg/L, the methane wont explode. On the same of aerosol concentration, S aerosol has a better explosion suppression effect than K.
