[0029] Specifically, both the air inlet pipe 12 and the air outlet pipe 11 are connected to the boiler. After the power supplies of the fan 21 and the heater 17 are connected, the heater 17 generates heat after being powered on. After the fan 21 is powered on, the gas in the boiler is pumped into the preheating box 10. The filter plate 22 filters the soot particles in the gas to prevent the soot particles from accumulating in the preheating box 10. The filtered soot particles fall into the collection groove above the collection plate 13. The filtered gas is heated by the heater 17 and discharged into the boiler through the air outlet pipe 11, thereby heating the boiler; When it is necessary to take out the filter plate 22 and the collection plate 13 for cleaning, the lifting plate 16 is moved upward, and the first sealing strip 18 and the second sealing strip 19 are separated, so that the fixed frame 20, the filter plate 22 and the collection plate 13 can be taken out from the strip-shaped through hole, thus facilitating the staff to clean the soot particles on the filter plate 22 and the collection plate 13; By arranging the fan 21, the heater 17, the preheating box 10, the air inlet pipe 12 and the air outlet pipe 11, the interior of the boiler can be heated, and the heat generated in the boiler can be recycled, thereby improving the heating efficiency and reducing the heating loss.

Thus, when the combustion material enters the material transfer box 30 through the material guide pipe 32, it is preliminarily crushed by the crushing rollers. The combustion material falls from the crushing rollers, and the crushing teeth 35 on the crushing rollers further crush the combustion material. Then, the crushed combustion material is transported into the interior of the boiler body 2 through the material transfer pipe 33 for combustion. By thoroughly crushing the combustion material, the effect of full combustion can be achieved, the combustion efficiency can be improved, and emissions can be reduced. The air inlet pipe 12 and the air outlet pipe 11 are both connected to the boiler. Connect the power supplies of the fan 21 and the heater 17. After the heater 17 is powered on, it generates heat. After the fan 21 is powered on, the gas in the boiler is pumped into the preheating box 10. The filter plate 22 filters the soot particles in the gas to prevent the soot particles from accumulating in the preheating box 10. The filtered soot particles fall into the collection tank above the collection plate 13. The filtered gas is heated by the heater 17 and discharged into the boiler through the air outlet pipe 11, thereby heating the boiler. When it is necessary to remove the filter plate 22 and the collection plate 13 for cleaning, move the lifting plate 16 upward, and the first sealing strip 18 and the second sealing strip 19 are separated. Then, the fixed frame 20, the filter plate 22, and the collection plate 13 can be taken out from the strip-shaped through hole, which facilitates the staff to clean the soot particles on the filter plate 22 and the collection plate 13. By setting the fan 21, the heater 17, the preheating box 10, the air inlet pipe 12, and the air outlet pipe 11, the interior of the boiler can be heated, and the heat generated in the boiler can be recycled, thereby improving the heating efficiency and reducing the heating loss.
