Abstract: An explosive combustion device for biological materials such as husks, cores, and chaff includes a feed unit having from upstream to downstream a pulverizer, a hopper, and a pneumatic conveyor; an air delivery unit having from upstream to downstream a vortex blower, an air tank, and an air volume regulator; a heating unit having from upstream to downstream a fuel source, a fuel flow control, and a heater; a combustion unit heated by the heater, the combustion unit being adapted to receive particles from the pneumatic conveyor and the compressed air from the air volume regulator; and a nozzle at an outlet of the combustion unit. The particles and the compressed air are mixed in the combustion unit turbulently to fully combust.
