To scale back the deflagration hazard effects of methane/air mixtures, in this work the synergistic effects of ammonium dihydrogen phosphate-modified dry water (MAP-DW)-C3HF7 inhibitors on the explosion parameters of methane had been experimentally investigated. Moreover, the synergistic thermal-chain inhibition mechanism of the compound inhibitor was revealed by kinetics analysis. The experimental results present that with the increase within the compound inhibitor, the Pmax and (dP/dt) max of ...
