| description | The invention provides an experimental device and method for measuring combustion and explosion characteristics of a dust cloud. The whole experimental device comprises an electric spark ignition device, a special quartz glass tube, a porous steady-flow powder injection pipeline, a pressure/temperature data acquisition device and a movable detachable fixing frame, and characteristic parameters such as the minimum ignition energy, the explosion pressure and the combustion temperature of the combustion and explosion of the dust cloud can be measured. By the porous gas flow divider designed by the invention, uniform and stable air injection can be realized; by an electric spark trigger circuit, electric sparks with multiple selectable energy levels of small energy and large energy can be realized, and high spark energy precision can be ensured. Explosion venting pieces with different sizes and the self-made movable detachable fixing frame are assembled on the top of the special quartz glass tube, and pressures a |
