[0002] Biomass pellets are made by cold-forming crushed biomass straw, forestry waste and other raw materials using rollers and ring dies at room temperature. The density of the raw materials is generally 0.1-0.13t / m3, and the density of the pellets after forming is 1.1-1.3t / m3, which is convenient for storage and transportation, and greatly improves the combustion performance of biomass. After compression molding, the volume of biomass is greatly reduced, making it easier to transport, store and use.

[0003] At present, some biomass pellet burning stoves have appeared on the market, such as the scheme CN206398699U, a biomass pellet burner, whose combustion furnace is connected to the hopper through a tubular screw feeder, and the combustion chamber is provided with a circulating air outlet. However, in actual use, it is difficult for the smoke of the combustion furnace to be completely discharged from the circulating air outlet of the combustion chamber. In addition, since the combustion furnace is directly connected to the feed pipe of the screw feeder, the smoke flows back along the feed pipe, resulting in the troublesome phenomenon of the hopper smoking upwards. The pellet burning stoves on the current market generally have the problem of hopper smoking. This scheme improves the feed pipe to solve this problem. Utility Model Content
