Biomass coal particle combustor

The utility model provides a biomass coal particle combustor and relates to a solid fuel combustor. The biomass coal particle combustor comprises a horizontal spiral propeller, a vertical spiral propeller, an inverse cone frustum type pot-shaped combustion body, a first air inlet pipe and a second air inlet pipe. A hollow interlayer is arranged on the side wall of the combustion body, multiple air holes are formed in the upper portion of the inner layer of the hollow interlayer, and the first air inlet pipe is communicated with the hollow interlayer from the outside; the discharging outlet of the horizontal spiral propeller is communicated with an inner cavity of the combustion body through the lower portion of the side wall of the combustion body; a spindle of the vertical spiral propeller is a hollow pipe with the upper end sealed, a spiral piece is located on the lower portion of the inner cavity of the combustion body and fixed in the middle of the spindle, the lower portion of the spindle extends out of the lower end of the combustion body and is connected with a drive device, and multiple air outlets are formed in the pipe wall of the upper portion of the spindle and correspond to a combustion area of the combustion body; a material pushing device with claws is arranged on the spindle and located below all the air outlets, blind holes are formed in the claws and communicated with an inner hole of the spindle, multiple small air holes are formed in the upper sides of the claws and communicated with the blind holes, and the lower end of the spindle is communicated with the second air inlet pipe; the discharging outlet of the horizontal spiral propeller right faces the middle portion of the spiral piece of the vertical spiral propeller. The biomass coal particle combustor can avoid impurity adhesion and black smoke.
