摘要

The flame resistance characteristics of corrugated flame-retardant system for hydrogen/methane explosion were researched by visualization experiment. The influence laws of structure parameter and hydrogen doping ratio on the explosion resistance parameters were summarized. Result indicates that the flame could be effectively quenched and there was a clear correspondence between flame propagation and explosion parameters at the front and rear ends. Flame propagation at the front-end could be greatly affected by flame-retardant system, thereby affecting its propagation velocity inside the narrow channel. As the flame resistance failed, the flame at the rear-end would appear an obvious acceleration. As the porosity and hydrogen ratio increased, the failure probability continued to increase. An increase in flame-retardant element thickness was conducive to flame resistance success. Above factors could affect the flame resistance effect by influencing the intensities of flame and pressure wave entering front-end of flame-retardant system, as well as the degree of weakening inside the narrow channel.
