The invention relates to
biomass fuel burning equipment and a burning method thereof. The
biomass fuel burning equipment comprises a burning furnace and a blowing device, a rotatable fire grate and a fire grate rotation driving device are arranged in the burning furnace, the fire grate comprises a circular bottom rotating plate, a plurality of groups of funnel caps, fireproof clay
layers, an ash
pipe and a sealing plate, wherein the funnel caps are arranged above the bottom rotating plate, the fireproof clay
layers are paved on the funnel caps, the ash
pipe is connected to the circular center of the bottom rotating plate, and the sealing plate is fixed at the outer edge of the bottom rotating plate. The
biomass fuel burning equipment and the burning method thereof are applicable to assorted boilers, water heaters, air heaters and the like, and are used for burning biomass energy, fuel is uniformly arranged and suspended on the fire grate to burn after entering the burning furnace, and burning efficiency is high. Ash after power burning can be discharged completely from the ash
pipe, an air inlet
system is prevented from being blocked by the ash during burning, and the ash is collected and recycled, is convenient to clean and free of affection on the environment.
