Oxygen-supplementing biomass combustion furnace

Abstract

The invention relates to a burning breaking-out device, in particular to an oxygen-supplementing biomass combustion furnace, which comprises a hearth (2). A hopper (1) and a flame opening (3) are arranged on the waist portion of the hearth (2), and an air inlet (6) is arranged at the bottom of the hearth (2), and the hearth (2) is located in a temperature-resisting casing (4). An air cooling cavity (5) capable of leading in flowing air is formed between the hearth (2) and the temperature-resisting casing (4), and the flame opening (3) is provided with an oxygen-supplementing hole (7) communicated with the air cooling cavity (5). The flowing air is adopted to perform cooling and thermal insulation of a hearth wall, loss of heat of the hearth can be greatly reduced, the heat energy utilizing efficiency of a biomass combustor is greatly improved, oxygen is supplemented to the flame opening through the oxygen-supplementing hole, gas which is not combusted is fully combusted, and the fuel combustion efficiency is enhanced.

Description

technical field [0001] The invention relates to a combustion and flame-injection equipment, in particular to an oxygen-supplementing biomass combustion furnace. Background technique [0002] Biomass fuel is a new type of fuel made by screening, drying, extruding and other methods such as orange stalks, wood chips, and organic domestic waste. This kind of fuel uses some waste, so the biofuel Substance fuel is an environmentally friendly fuel. [0003] Biomass burner is a kind of burner specially used to burn biomass fuel, which has the advantages of high combustion efficiency and good effect. However, the biomass combustion currently on the market is generally used in boiler equipment. The traditional biomass burner furnace needs to be water-cooled, because the heat loss caused by the water-cooling system accounts for about 15% of the total heat, so the efficiency of heat energy use is very low. , but also a waste of precious water resources.

However, the biomass combustion currently on the market is generally used in boiler equipment. The traditional biomass burner furnace needs to be water-cooled, because the heat loss caused by the water-cooling system accounts for about 15% of the total heat, so the efficiency of heat energy use is very low. , but also a waste of precious water resources

[0004] When biomass fuel is gasified and burned in the furnace, the fuel is often not fully burned due to insufficient oxygen supply at the air inlet. On the one hand, it causes waste of fuel, and on the other hand, it emits harmful gases, which is not good for the environment.
