A new multifunctional biomass suspension deflagration test-bed is provided, which includes a closed combustion chamber. An integrated temperature and pressure sensor is arranged in the combustion chamber, and a high-speed camera and a laser concentration-measuring instrument are arranged outside the combustion chamber, which can monitor suspension deflagration. A bottom of the combustion chamber is provided with a hollow mushroom-shaped dispersion nozzle with a tray. A nozzle body is provided with a gas main-flow channel 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 vent hole is formed in a portion of the mushroom-shaped baffle plate which is corresponding to the gas main-flow channel. Each gas deflected-flow channel is inclined outward from bottom to top and directed to the mushroom-shaped baffle plate.
