[0002] Steam boiler is an important thermal energy equipment in industrial production, and its stable supply of fuel is crucial to the normal operation of the boiler. The traditional feeding method is to have workers put in fuel, which cannot meet the needs and is time-consuming and labor-intensive. In order to meet the continuous and stable demand for fuel by steam boilers, steam boiler feeding devices came into being. With the continuous development of technology, the performance requirements for steam boiler feeding devices are also getting higher and higher. Existing steam boiler feeding devices are usually composed of structures such as storage frames and guide racks. When in use, the fuel is directly stored in the storage frame and then put into the boiler through the guide rack. Although this type of device can realize feeding, due to the different sizes of fuels and different contact areas with the air, some larger fuels may not be fully burned, resulting in fuel waste, which reduces the fuel combustion efficiency to a certain extent.
