The lower end of the support legs 16 is fixedly connected to the top of the bottom plate 1. A fuel conveying mechanism is installed between the bottom of the silo 15 and the furnace drum 2. The fuel conveying mechanism is located above the feeding plate 9.

[0020] The fuel delivery mechanism includes three delivery pipes 17, which are arranged parallel to each other. The right end of each delivery pipe 17 is fixedly connected to the furnace drum 2, and the top of the left half of the three delivery pipes 17 is fixedly connected to the bottom of the silo 15. A rotating shaft 18 is provided inside each delivery pipe 17.
