Air supply system of solid particle fuel stove

Abstract

An air supply system of a solid particle fuel stove comprises an air blower (1), an air distribution chamber (2), a bottom box (3), a gasification combustor (4) and a feeding device (5). An inner cavity of the gasification combustor (4) is a gasification combustion chamber (411). An ash discharge and air inlet capable of communicating the gasification combustion chamber (411) of the gasification combustor (4) and the inner cavity of the bottom box (3) is formed in position, corresponding to an ash outlet (412) of the gasification combustor (4), of the bottom box (3) and a stove bottom plate. The air blower (1) is connected with the air distribution chamber (2) through a first-time air pipe (11). A communicating pipe (31) or a through opening is arranged between the air distribution chamber (2) and the bottom box (3). The air distribution chamber (2) is further connected with the feeding device (5) through a third-time air pipe (54). According to the air supply system of the solid particle fuel stove, oxygen can be supplied through multiple layers and multiple stages so that fuel can be provided with sufficient oxygen at all combustion stages in different combustion positions, the combustion efficiency is high, and the fire power is stable.

Description

technical field [0001] The invention relates to a stove, in particular to an air supply system for a solid particle fuel stove. Background technique [0002] Solid pellet fuel mainly includes biomass pellet fuel, mineral pellet fuel, etc. [0003] Biomass pellet fuel is referred to as biomass fuel for short. Biomass fuel is mostly agricultural waste and wood waste (stem crops, peanut shells, bark, sawdust and solid waste (furfural residue, edible fungus residue, etc.)) after processing Produces lumps (mainly cylinders) of fuel. Biomass fuel has the following characteristics: high calorific value, no corrosion of boilers, no air pollution, clean sanitation, very little ash, and ash is a recyclable, profitable and renewable energy source. [0004] Therefore, biomass fuel is an ideal fuel for people's daily production and life, and it is the development direction of environmental protection and sustainable energy; however, the gas supply system of the current biomass fuel sto...

AI Technical Summary

Problems solved by technology

[0005] 1. Oxygen is supplied to the lower part at one time. Due to the strong wind, the temperature of the lower part is not high, and the combustion and gasification effect is not good;

[0006] 2. After the fuel is gasified, it is far away from the air inlet at the lower part of the stove, there will be insufficient oxygen, insufficient combustion, waste of fuel resources, and environmental pollution;

[0007] 3. Directly enter the cold air at one time. The air is not preheated, which affects the combustion effect. It is far less effective than hot air with an initial temperature above 300 degrees.
