Novel combustion box of wood particle furnace

Abstract

The invention discloses a novel combustion box of a wood particle furnace. The novel combustion box comprises a combustion box wall and a combustion box bottom plate, the combustion box wall is provided with a hollow interlayer air duct, an air supply outlet communicating with the interlayer air duct is formed in the outer wall of a combustion box body, and a bottom air inlet hole and a top air inlet hole which communicate with the interlayer air duct are respectively formed in the bottom and the top of the inner wall of the combustion box body. The combustion box wall is arranged to be of the hollow interlayer structure, so that a part of air entering the interlayer air duct can enter from the bottom air inlet hole to be mixed with ignited wood particles for primary combustion; and the other part of air is blown out from the top air inlet hole after being preheated by the interlayer air duct, and is mixed with hot flue gas and dust after primary combustion for secondary combustion. Two times of combustion can raise the roasting temperature in a furnace chamber to more than 800 Fahrenheit degree, on the other hand, flue gas and dust are burnt as much as possible, the cleanliness in a hearth is greatly improved, the combustion efficiency and the fuel utilization rate are improved, and the energy-saving and environment-friendly advantages of the wood particle furnace are highlighted.

Description

technical field [0001] The application belongs to the technical field of combustion boxes for wood pellet stoves (including food ovens and heating stoves), and in particular relates to a novel combustion box for wood pellet stoves. Background technique [0002] With the increasing use of wood pellet stoves (including food ovens and heating stoves) on the market, people are increasingly pursuing thermal efficiency during use, high environmental cleanliness, and the convenience of cleaning residues after combustion. [0003] However, the combustion box, the core component of a traditional wood pellet stove, is basically a single-wall barrel-shaped cylinder with an open top, and wood pellets and air are mixed and burned at the bottom of the cylinder. Since only a single incomplete combustion can be achieved, more Smoke and dust not only cause pollution but also waste fuel, which is not conducive to the environmental protection goals of cleaning, energy saving and emission reduc...
