Description

Technical Field

[0001] The invention relates to the field of biomass stoves, and in particular to an environmentally friendly biomass combustion stove. Background Art

[0002] Biomass semi-gasification stove is a new generation of efficient, environmentally friendly, energy-saving cooking and heating stove. It is also called high-efficiency and low-emission stove because of its high thermal efficiency and low smoke emission. It uses combustible biomass (firewood, straw, sawdust, husk, leaves, etc.) and coal as fuel. By gasifying the biomass in the furnace to produce combustible gas, the combustible gas is burned again under the secondary oxygen supply in the upper layer of the furnace, achieving full combustion of the biomass, improving the thermal efficiency of the stove while reducing smoke emission. Compared with traditional large stoves, this technology can greatly improve the overall thermal efficiency of the stove, achieve the purpose of saving firewood and coal, reduce smoke emission through secondary oxygen supply and gasification combustion, and the smoke will be discharged to the outside through the smoke pipe, solving the problem of burning large stoves, high pollution, high emissions, and high energy consumption in rural areas, and truly achieving the purpose of high efficiency, environmental protection, and energy saving. It is an energy-saving stove that integrates multiple functions such as boiling water, cooking, insulation, and heating in farmers' homes.

[0003] With the strengthening of environmental protection efforts, in order to reduce the adverse impact on the environment, biomass combustion furnaces have been widely used. In actual use, when using a biomass furnace to bake and dry product raw materials, the baking chamber and the combustion chamber are directly connected, and the temperature in the combustion chamber is extremely high, and it is baked by the flames in the furnace, causing the connection between the drying chamber and the furnace body to be easily damaged and need to be replaced regularly, which is time-consuming and labor-intensive and increases production costs; and when adding fuel to the biomass combustion furnace, the commonly used feeding mechanism is directly placed in the combustion chamber, which has the same problem.
