Particle burner

Abstract

The invention discloses a particle burner, belongs to the field of burning equipment, and solves the problem of inconvenience in ash removal or poor ash falling effect of a particle burner in the prior art. According to the technical scheme, a through hole for air intake and ash falling is formed in the bottom surface of a burner body, and a grid structure for supporting particle fuel is arranged above the through hole; and the grid structure comprises a first-layer supporting body and second-layer supporting bodies which are fixed to the burner body, the first-layer supporting body is lower than the adjacent second-layer supporting bodies , the second-layer supporting bodies are distributed in a staggered manner relative to the first-layer supporting body in the vertical direction, and a first channel used for ash falling and air inlet is formed between the first-layer supporting body and the second-layer supporting bodies. The width of the first channel is smaller than the diameter D of particle fuel, the distance L2 between every two adjacent second-layer supporting bodies is larger than D and smaller than 2D, a feeding port is located above the grid structure, the height difference of the feeding port is H, and H is not smaller than 3D. The particle burner is mainly used for automatic ash falling, a user does not need to clean ash, and the ash falling effect is good.

Description

technical field [0001] The invention relates to the field of combustion equipment, in particular to a particle burner. Background technique [0002] Existing pellet burners, such as barbecue grills, use a pellet burner that is basically a closed bottom structure. After each use, a vacuum cleaner is used to clean up the ashes after the pellet fuel is burned, which is very inconvenient. bad. Another example is a heating furnace, which is generally equipped with a layer of grate for ash falling, but biomass pellet fuel is generally a cylindrical structure extruded from biomass raw materials, with a diameter of 4-6 mm and a length of 1-6 cm. If there is no external force, the ash produced by the combustion of pellet fuel will remain cylindrical, so it is difficult to fall directly, resulting in poor ash fall efficiency and effect.

[0002] Existing pellet burners, such as barbecue grills, use a pellet burner that is basically a closed bottom structure. After each use, a vacuum cleaner is used to clean up the ashes after the pellet fuel is burned, which is very inconvenient. bad

Another example is a heating furnace, which is generally equipped with a layer of grate for ash falling, but biomass pellet fuel is generally a cylindrical structure extruded from biomass raw materials, with a diameter of 4-6 mm and a length of 1-6 cm. If there is no external force, the ash produced by the combustion of pellet fuel will remain cylindrical, so it is difficult to drop it directly, resulting in poor ash fall efficiency and effect. After burning for a long time, other components are still needed to assist in breaking up the ash to clean it. Gray, not only the structure is more complex, the production cost is higher, but also requires user participation, it is not convenient to use
