[0024] In this embodiment, during the use process, the sealing cover 12 is removed from the top of the feed hopper 11, and the furnace body 2 is fed through the inside of the feed hopper 11. After the feeding is completed, the sealing cover 12 is put back to seal the inside of the furnace body 2. When a large amount of flue gas is generated after the furnace base 1 and the furnace body 2 process the materials, the high-temperature resistant blower 14 is started to drive the flue gas to flow rapidly.
