[0025] The principle of the utility model is as follows: when in use, the wind enters from the first wind duct 15 and the second wind duct 16, and the wind enters the second cyclone wind chamber 10 from the first wind duct 15. The second cyclone wind chamber 10 is provided with a cyclone plate 12. The wind entering the second cyclone wind chamber 10 passes through the cyclone plate 12 to form a primary cyclone wind. When the primary cyclone wind passes through the obliquely cut air contraction tube 18 on the outer cylinder 3, the primary cyclone wind gathers toward the center point to realize the concentration of the flame. The wind enters the cyclone wind chamber 8 through the second wind duct 16. The wind entering the cyclone wind chamber 8 passes through the second cyclone plate 9 forms secondary swirl wind, which enters the central cavity 1 to assist combustion. Another part of the wind in the swirl wind chamber 8 passes through the swirl tube 11 to form tertiary swirl wind, which passes through the inner cylinder 4 and enters the central cavity 1 to assist combustion. The extension lines of the center lines of the swirl tube 11 intersect at a point; the extension lines of the center lines of the swirl tube 11 intersect in the central cavity 1, and the tertiary swirl winds are concentrated at a point in the central cavity 1. The wind directions of the primary swirl wind, the secondary swirl wind, and the tertiary swirl wind are different, and the combustion effect is guaranteed by mutual cooperation. , reducing the ash content, greatly improving the combustion effect of biomass fuels, the first air duct 15 and the second air duct 16 are respectively provided with regulating valves 17, which realize the function of adjusting the wind force respectively. After use, when the burner head needs to be cooled, the refrigerant is injected into the water jacket 21 through the water inlet pipe 20. The refrigerant circulates in the water jacket 21 to cool the burner head. In order to avoid the air impurities entering during use clogging the swirl tube 11 and the swirl plate 12, a filter component is set to filter out the ash in the air through the filter mesh component 23. Dust is prevented from clogging the cyclone tube 11 and the cyclone plate 12. When the filter assembly 23 needs to be cleaned, the fixed column 27 is translated to drive the limit block 24 to move, drive the limit block 24 to disengage from the limit groove, and take out the filter assembly 23. When installing, the fixed column 27 is translated to drive the limit block 24 to move, and the limit block 24 is aligned with the limit groove on the filter assembly. The fixed column 27 is loosened, and under the action of the elastic force of the spring 25, the limit block 24 extends into the limit groove to fix the filter assembly 23, which is convenient for disassembly and installation.
