Description

Technical Field

[0001] The utility model relates to the technical field of biomass gasification devices, in particular to a biomass gasification device which is convenient for feeding. Background Art

[0002] Biomass gasification refers to the process in which, under certain thermodynamic conditions, the polymers in biomass undergo pyrolysis, oxidation, and reduction reforming reactions through the action of air (or oxygen) and water vapor, and are ultimately converted into combustible gases such as carbon monoxide, hydrogen, and low-molecular hydrocarbons. A biomass gasification device is a device that converts biomass energy into gaseous fuel. In actual use, manual addition is generally used for feeding, and the feed amount is difficult to accurately control. When the feed amount is too large, the biomass is difficult to fully gasify, and when the feed amount is large, it is easy to cause the feed pipe to be blocked, affecting the working efficiency of the device. Therefore, a biomass gasification device that is easy to feed is provided. Utility Model Content
