the biomass burner is arranged in a cavity of a boiler (19), biomass fuel is conveyed into the upper part of the biomass burner in the cavity of the boiler (19) by a feeding mechanism (20), is scattered in the center of a stirring disc (1) in a free falling manner, a motor I (11) drives the stirring disc (1) to rotate, a plurality of deflector rods (1-1) of the stirring disc (1) uniformly distribute the biomass fuel on the annular surface of an inner ring (5-1), a middle inner ring (5-2), a middle outer ring (5-3) and an outer ring (5-4) of the combustion disc (5), simultaneously a wind supply motor conveys high-pressure wind to a plurality of wind inlets I (14-6), wind inlets II (14-8), wind inlets III (14-10) and wind inlets IV (14-12) on a wind cavity tray (14) through pipelines, a ring of a wind balancing fender (6-11), a two ring wind balancing fender (6-12), a three ring wind balancing fender (6-13) and a four ring wind fender (6-14) are uniformly distributed on the annular surface of the combustion disc (5-4), the wind balancing motor converts high-pressure wind into wind from the wind inlet I (14-6), the wind balancing ring II (14-10) and the wind balancing ring (5-12) into the wind balancing ring (5-4) on the wind balancing ring (5-5), the biomass fuel is conducted to a combustion space in the boiler to supplement oxygen and support combustion, when the burnt biomass fuel gradually enters an inner ring (5-1), an intermediate inner ring (5-2), an intermediate outer ring (5-3) and an outer ring (5-4) to carry out tail combustion, namely carbon combustion, the biomass fuel is blocked by an ash blocking (9), a plurality of deflector rods (1-1) of a stirring disc (1) stir residues after tail combustion into an ash discharge box (13-1) through an ash outlet (9-1), and the biomass fuel residues are crushed by two slag breakers (13-5) of a slag breaking device (13) and discharged through a lower port of the ash discharge box (13-1).
