1. A biomass suspension deflagration test-bed, the test-bed comprising a combustion chamber that is closed, wherein a tray is arranged at a bottom of an inside of the combustion chamber, and a hollow mushroom-shaped dispersion nozzle is arranged at the tray and is externally connected to a test gas source;
wherein the hollow mushroom-shaped dispersion nozzle comprises a nozzle body, the nozzle body is provided with a gas main-flow channel located at a center thereof and gas deflected-flow channels arranged around the gas main-flow channel, a mushroom-shaped baffle plate is arranged above the nozzle body, the gas main-flow channel extends upward to the mushroom-shaped baffle plate, a portion of the mushroom-shaped baffle plate which is corresponding to the gas main-flow channel is formed with a vent hole; each of the gas deflected-flow channels is inclined outward from bottom to top and directed towards the mushroom-shaped baffle plate, wherein gas passes through the gas deflected-flow channels and then is reflected by the mushroom-shaped baffle plate, and the gas after being reflected blows up biomass powder fuel on the tray.
