Particle combustion furnace

Abstract

The invention discloses a particle combustion furnace, belongs to the field of combustion equipment, solves a problem of inconvenience in ash removal or poor ash falling effect of a combustor in the prior art, and adopts the technical scheme that a through hole for air intake and ash falling is formed in the bottom surface of the combustor, and a grid structure is arranged above the through hole; the grid structure comprises a first-layer supporting body and a second-layer supporting body which are fixed to the combustor, the first-layer supporting body is lower than the adjacent second-layer supporting body, the second-layer supporting body is distributed in a staggered mode in the vertical direction relative to the first-layer supporting body, and a first channel is formed between the first-layer supporting body and the second-layer supporting body; the width of the first channel is smaller than the diameter D of granular fuel, a distance L2 between every two adjacent second-layer supporting bodies is larger than D and smaller than 2D, the feeding port is located above the grid structure, the height difference is H, H is not smaller than 3D, and an ash receiving disc is arranged at the position, located below the combustor, of the bottom of the furnace body. The particle combustion furnace is mainly used for automatic ash falling, good in ash falling effect and convenient for users to clean ash.

Description

technical field [0001] The invention relates to combustion equipment, in particular to a particle combustion furnace. Background technique [0002] Existing pellet burning stoves, such as barbecue grills, use a burner that is basically a closed bottom structure. After each use, the ashes after the pellet fuel is burned are cleaned by a vacuum cleaner, which is very inconvenient and the user experience is not good. good. Another example is the heating furnace, which generally has a layer of grate for ash falling, but the pellet fuel of biomass is generally an extruded cylindrical structure with a diameter of 4-6mm and a length of 1-6cm, and the pellet fuel burns to produce If there is no external force, the ash will remain cylindrical, so it is difficult to fall directly, resulting in poor ash fall efficiency and effect. After burning for a long time, it still needs other components to assist in breaking up the ash to clean it. Not only the structure It is more complicated,...

Another example is a heating furnace, which is generally equipped with a layer of grate for falling ash, but the pellet fuel of biomass is generally an extruded cylindrical structure with a diameter of 4-6mm and a length of 1-6cm, and the pellet fuel burns to produce If there is no external force, the ash will remain cylindrical, so it is difficult to fall directly, resulting in poor ash fall efficiency and effect. After burning for a long time, it still needs other components to assist in breaking up the ash to clean it. Not only the structure It is more complicated, the production cost is higher, and it requires user participation, so it is not convenient to use
