Description

Technical Field

[0001] The utility model relates to the technical field of biomass gasifiers, in particular to an updraft biomass gasifier. Background Art

[0002] Biomass gasifier is a device that uses biomass as fuel for gasification. Its working principle is to produce combustible gas through the thermochemical reaction of biomass in the furnace, such as drying, thermal decomposition (drying), reduction and oxidation. These combustible gases are then burned again under the secondary oxygen supply in the upper layer of the furnace, achieving full combustion of biomass, thereby improving the thermal efficiency of the stove and reducing smoke emissions. Biomass gasifiers use biomass shaped fuels, such as chopped firewood, firewood, straw, corn cobs, various fruit shells, and biomass briquettes. Compared with traditional stoves, this stove has higher thermal efficiency and can significantly reduce smoke emissions, thus achieving the goals of high efficiency, environmental protection, and energy saving. Biomass gasifiers are not only suitable for household cooking, heating, boiling water and other scenarios, but can also be used in industrial fields, such as industrial boilers (hot water boilers, thermal oil boilers, steam boilers) and some industrial kilns such as steel kilns, glass kilns, ceramic kilns, etc., using the gas produced by them instead of fuel oil or natural gas.

The gasifier controls the reaction temperature of the furnace through the secondary air and bottom steam arranged at the bottom to ensure the stable operation of the system, and the sealing of the biomass raw material to the combustion gas is achieved through the throat section arranged at the top. The utility model has the characteristics of stable equipment structure, convenient feeding, and smooth operation. The raw material adaptability of this device is wide, and it can process a variety of biomass.
