Description

Technical Field

[0001] The present invention relates to the field of biomass gasification, and in particular to a biomass gasifier. Background Art

[0002] A biomass gasifier uses organic biomass as fuel, rapidly converting it into high-energy fuel gas (primarily methane) through gasification technology. The biomass gasifier operates by breaking down biomass into combustible gases through a high-temperature reaction. The resulting fuel gas is then burned to generate energy. The raw material for biomass gasifiers is widely available and is an inexhaustible, renewable resource. Biomass gasifiers are particularly suitable for cooking, frying, heating water, bathing, and heating in rural homes. They are also suitable for boilers, greenhouse heating, large-scale heating, and small and medium-sized restaurants.

[0003] In the industrial sector, biomass gasifiers have demonstrated enormous potential for application. In existing technologies, when adding fuel to a biomass gasifier, fuel accumulation at the feed port is common due to its diverse forms (such as granules, lumps, and powders), high moisture content, or poor fluidity. This leads to incomplete combustion and decomposition, resulting in a reduction in gas output per unit of fuel. To maintain the required gas output, increased fuel input is required, increasing the operating cost of the biomass gasifier. Furthermore, if the feed port is airtight during operation, external air can enter the furnace, affecting the stability of the gasification process and reducing the gasification efficiency of the biomass gasifier.
