Two-phase mixed combustion and explosion experiment system and experiment method

The invention provides a two-phase mixed combustion and explosion experiment system and experiment method, and the experiment system aims at exploring the dynamic law of the propagation characteristics of combustion and explosion waves formed by a combustible gas and coal dust two-phase mixture in a typical pipeline. The experimental system is used for acquiring burning and explosion characteristic data of a two-phase mixture under different coal dust particle sizes and different combustible gas doping concentrations, and consists of a burning and explosion pipeline system, a gas charging and distributing system, a dust spraying system, an ignition system and a data acquisition system. According to the invention, the dynamic law of the propagation characteristic of the explosion wave formed by the combustible gas and coal dust two-phase mixture in a typical pipeline can be explored, and the explosion characteristic data of the two-phase mixture under different coal dust particle sizes and different hydrogen d
