The gas can be introduced through the air intake pipe for instantaneous air intake. At the same time, auxiliary shielding can be achieved by adopting a gravity stopper, which can effectively avoid the leakage of fuel when the conveying screw piece conveys the fuel. The overall use is more flexible and practical. At the same time, the release of the fuel is more uniform, the fuel combustion efficiency is improved, and local accumulation is avoided. The overall structure has a lower cost and is more suitable for use in heavy-duty burner boilers such as small power plants. The fuel is introduced at the feed pipe. By adopting the drive motor, the conveying cylinder and the conveying screw piece can be driven to rotate to realize a material conveying work. When the conveying screw piece rotates, the material can be driven to advance. At the same time, the high-pressure gas of the air pump can be introduced through the air intake pipe. Under the action of the airflow, the holes on the conveying cylinder are exhausted to blow out the fuel, such as coal powder, to realize the application of a fuel.

[0019] In addition, by setting up the air suction cleaning parts, the structure is simple and stable, which can assist in the linkage cleaning work. At the same time, the combustion exhaust gas can be fully utilized to heat the water source. On the one hand, it can filter out dust and impurities, and on the other hand, it can reuse heat energy and can be used for heating and other scenarios. By adopting the guide absorption parts, another important function is to guide the blown coal powder. The overall structure is simpler and more practical.
