Abrégé

The present invention relates to the field of burning devices, and disclosed is a particle burning furnace, for solving the problems in the prior art that backfire may occur in the burner from a feeding port in a big fire state, and a primer is difficult to maintain and is extinguished in a small fire state. A technical solution solving the problems mainly comprises: a burner is provided in a furnace body; the top end of the burner is open; a feeding port is formed in the sidewall of the burner; a through hole for air inlet and ash falling is formed in the bottom surface of the burner; a grate for supporting a particle fuel is provided above the through hole; an assistive supporting body for maintaining primer is arranged blow the grate; the assistive supporting body is higher than the through hole; and the assistive supporting body is located at one side below the feeding port, and the arrangement range of the assistive supporting body does not exceed 1/2 of the area covered by the grate. The present invention is mainly used for realizing that backfire is not prone to occur at the feeding port in the big fire state, and fire extinguishing can be avoided in the small fire state.

Abrégé

Disclosed in the present invention is a pellet combustor, relating to the field of combustion apparatuses. The problem of inconvenient ash clearing or a poor ash falling effect of a pellet combustor in the prior art is solved. According to a technical solution to the problem, a through hole for air inlet and ash falling is provided in a bottom surface of a combustor body, a grid structure for supporting pellet fuel is arranged above the through hole, the grid structure comprises a first layer of support bodies and a second layer of support bodies which are fixed to the combustor body, the first layer of support bodies are lower than the adjacent second layer of support bodies, the second layer of support bodies are distributed in a staggered manner relative to the first layer of support bodies in a vertical direction, first channels for ash falling and air inlet are provided between the first layer of support bodies and the second layer of support bodies, each first channel has a width smaller than a diameter D of the pellet fuel, a distance L2 between every two adjacent support bodies of the second layer is larger than D and smaller than 2D, and a feeding port is located above the grid structure, with a height difference being H, wherein H is not smaller than 3D. The present invention is mainly used for automatic ash falling without requiring ash cleaning by a user, and has a good ash falling effect.
