Technical Field
[0001] This utility model belongs to the field of gasification furnace technology, specifically relating to a feeding mechanism. Background Technology
[0002] A gasifier is a device that converts solid or liquid fuels into combustible gases (such as syngas and coal gas), and is widely used in industrial energy, chemical production, and biomass energy utilization. Through high-temperature (above 700°C) and oxygen-limited environments, the carbon and hydrogen elements in the fuel undergo pyrolysis, oxidation, and reduction reactions, ultimately producing combustible gases mainly composed of CO, H2, and CH4, while potentially generating byproducts such as tar and ash. Existing gasifier feeding mechanisms are difficult to precisely control the feed rate and are prone to clogging, making cleaning inconvenient. Summary of the Invention
