The top of the box body 4 has a storage trough 6. The bottom of the box body 4 has multiple adjustable support structures and a blower structure. The box body 4 has a connecting channel 12 that cooperates with the feed inlet 2 and a control panel 7. The connecting channel 12 has a conveying auger 18. One end of the conveying auger 18 is connected to the connecting channel 12 through a fixed arm 19. The other end of the conveying auger 18 is connected to a drive motor 20. The drive motor 20 is connected to the installation position inside the box body 4 through a fixed seat 21. The end of the connecting channel 12 that extends into the feed inlet 2 has a combustion position 22. The combustion position 22 has multiple sets of ventilation holes 23 that cooperate with the blower structure and an igniter 24.

[0025] In a preferred embodiment, the top of the housing 4 is provided with a maintenance hatch 5, which facilitates the inspection and maintenance of the internal structure of the housing 4.

[0026] In a preferred embodiment, the adjustable support structure includes fastening bolts 8 mounted on the outer wall of the housing 4. The fastening bolts 8 engage with adjusting grooves 10 mounted on the support legs 9. The bottom of the support legs 9 is equipped with self-locking casters 11. This allows for flexible adjustment of the biomass pellet fuel replacement structure 3, making it suitable for the feed inlets 2 of various conventional combustion furnaces.

[0027] In a preferred embodiment, the blower structure includes a blower 13 located at the bottom of the housing 4. The blower 13 is connected to a ventilation hole 23 via a ventilation duct 14 located at the bottom of the connecting channel 12. This bottom-intake design ensures a reasonable and stable structure, guaranteeing complete fuel combustion.

[0028] In a preferred embodiment, the storage tank 6 is equipped with a material level sensor 16. This sensor automatically detects the material level and prompts for replenishment.

[0029] In a preferred embodiment, the connecting channel 12 is equipped with a material feeding trough 17. Material feeding ensures a continuous and stable supply of biomass pellet fuel, enabling stable combustion for heating.

[0032] The method of using this utility model is as follows:

[0033] Fuel storage and transportation:

[0034] Biomass fuel is stored in the storage tank 6 at the top of the box 4. When the material level sensor 16 detects that the fuel is insufficient, it can trigger an alarm or an automatic replenishment mechanism. The conveying auger 18 is driven by the drive motor 20 to rotate and continuously feed the biomass fuel in the storage tank 6 into the combustion position 22 along the connecting channel 12 to ensure the continuity and stability of the fuel supply.

Some of the ventilation holes are set at an angle, which helps to form a more uniform airflow distribution and promotes complete combustion of fuel. At the same time, the side angled ventilation holes can prevent the flame from burning back into the conveying channel and ensure safety.

[0039] Ignition and Combustion Management:

[0040] An igniter 24 is installed at the combustion position 22, which can quickly ignite the biomass fuel at the initial stage of startup. After that, the blower volume and fuel supply rate are automatically adjusted according to the combustion situation to maintain a stable and efficient combustion state.
