Description

Technical Field

[0001] This utility model relates to the field of gasification boiler technology, specifically to a biomass gasification boiler. Background Technology

[0002] Coal-fired boilers often suffer from excessive emissions and severe pollution, and their resources are finite and non-renewable. In contrast, biomass boilers utilize plant straw, weed wood, and grain husks as raw materials. These materials are widely available, readily accessible, renewable, and have low operating costs. They are now widely used in both urban and rural areas, changing energy consumption patterns, improving the utilization rate of renewable energy, and significantly alleviating the tight supply and demand situation for primary energy sources.

[0003] Chinese Patent CN222809417U discloses a biomass gasification boiler, including a boiler body. An automatic feed inlet is fixedly connected to the upper surface of the boiler body. The automatic feed inlet is installed in conjunction with a sliding device. A conveyor belt is provided on one side of the automatic feed inlet. A rolling roller is slidably connected to the inner wall of the conveyor belt. A three-dimensional support is fixedly connected to both sides of the rolling roller. A first generator is fixedly connected to the outer surface of one side of the three-dimensional support. This allows workers to easily control the opening and closing of the feed inlet, preventing accidental scalding from steam when adding materials during boiler operation. Closing the L-shaped plate prevents gas from escaping from the boiler, which could reduce operating efficiency or cause environmental pollution due to exhaust gas overflow. The conveyor belt allows workers to easily feed raw materials into the boiler without manual intervention, saving time and preventing workers from entering the boiler, thus improving safety.

[0004] However, the above technical solution has the following shortcomings: the biomass raw materials enter the boiler body directly through the feed inlet, and the biomass raw materials falling into the boiler body tend to accumulate at the feed inlet. It is difficult for the biomass raw materials to be evenly distributed in the boiler body, which makes it difficult for the biomass raw materials falling into the boiler body to react fully and affects the utilization rate of biomass raw materials.
