Problems solved by technology

[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

Embodiment 1

[0029] The present invention provides a pellet burner, such as Figure 1 to Figure 6 As shown, it includes a burner body 1 with a combustion chamber 100, the top of the burner body 1 is open, the side wall of the burner body 1 is provided with a feed port 101, and the bottom of the burner body 1 is provided with a support for the particulate fuel 9. Grid structure, the grid structure includes a first layer of support 11 and a second layer of support 12 fixed to the burner body 1, the first layer of support 11 is lower than the adjacent second layer of support 12, the second layer of support The supporting body 12 is staggered in the vertical direction relative to the first layer of supporting body 11, and there is a first channel 102 for dust falling and air intake between the first layer of supporting body 11 and the second layer of supporting body 12. The first channel 102 The width W1 of the particle fuel 9 is less than the diameter D of the particle fuel 9, the distance L2...

Embodiment 2

[0038] Such as Figure 7 As shown, the grid structure in this embodiment is formed by wavy sheet metal parts, the wavy troughs on the sheet metal parts form the first layer of support 11, and the wavy peaks on the sheet metal parts form the second layer The supporting body 12 is provided with a through hole forming a first channel 102 between the trough and the crest on the sheet metal part. The outer periphery of the sheet metal part can be adapted to the inner wall of the burner body 1 , so the gap 106 mentioned in the first embodiment may not exist. In order to prevent ashes from accumulating on the first-layer support body, the upper surface of the first-layer support body can be designed as a convex arc surface as much as possible.

[0039] For other content not described in this embodiment, reference may be made to Embodiment 1.

Embodiment 3

[0041] Such as Figure 8 and Figure 9 As shown, an auxiliary support body 14 for maintaining the primer is provided under the first layer of support body 11, the auxiliary support body is higher than the through opening, and the auxiliary support body 14 is located on the side below the feed port 101 and the range of setting does not exceed the grid 1 / 2 of the area covered by the structure, where 1 / 2 is an approximate number, and deviations are allowed, so as not to affect the normal dust fall and air intake. Adding the auxiliary support body 14 has two functions. On the one hand, in the state of high fire, it can reduce the ash falling efficiency and the air intake below the feed port 101, and the combustion efficiency of the pellet fuel at this position can be effectively controlled, so as to effectively avoid the ash falling. The occurrence of tempering at the feed port 101, on the other hand, is to maintain the primer in a low fire state to avoid extinguishing. In this ...

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.
