Particle combustion furnace

Abstract

The invention discloses a particle combustion furnace, and belongs to the field of combustion equipment. The problems that in the prior art, the situation of backfire possibly happens to a combustor from a feed port in a big fire state, and the situation that primers are hard to maintain and are extinguished is prone to happening in a small fire state are solved. According to the main technical scheme for solving the problems, a combustor is arranged in a furnace body, the top end of the combustor is open, a feeding port is formed in the side wall of the combustor, a through port used for air inlet and ash falling is formed in the bottom face of the combustor, a fire grate used for supporting particle fuel is arranged above the through port, an auxiliary supporting body used for maintaining primers is arranged below the fire grate, the auxiliary supporting body is higher than the through port, the auxiliary supporting body is located on one side below the feeding port, and the set range does not exceed 1 / 2 of the area covered by the fire grate. The particle combustion furnace is mainly used for achieving the aims that backfire is not prone to happening to the feeding port in a big fire state, and extinguishing can be avoided in a small fire state.

Description

technical field [0001] The invention relates to the field of 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 is generally equipped with a layer of grate for ash falling, but the pellet fuel of biomass is generally an extruded cylindrical structure with a diameter of about 6mm and a length of 2 to 6cm, and the pellet fuel produced by combustion 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...

Problems solved by technology

[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 is generally equipped with a layer of grate for ash falling, but the pellet fuel of biomass is generally an extruded cylindrical structure with a diameter of about 6mm and a length of 2 to 6cm, and the pellet fuel produced by combustion 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 is relatively Complicated, expensive to produce, and requires user involvement, making it inconvenient to use

In addition, the burner may flash back from the feed port in a high-fire state, and it is easy to have a primer that is difficult to maintain and go out in a low-fire state.
