[0002] Biomass power generation refers to the power generation activities using biomass energy. Biomass energy refers to the energy stored in various organic substances produced through photosynthesis, including plants, animals, microorganisms and their waste.

[0003] After searching, the patent document with publication number: CN218763357U discloses a biomass power generation straw combustion device, which relates to the field of biomass combustion power generation technology, including a biomass fuel combustion chamber, partitions are arranged on both sides of the interior of the biomass fuel combustion chamber, and the side surfaces of the partitions are provided with inclined through grooves. The side surfaces of the partitions close to the inner walls of the biomass fuel combustion chamber are fixedly connected with dust filters, and induced draft fans are arranged on both sides of the top of the biomass fuel combustion chamber, and the two ends of the induced draft fan are fixedly connected to the support duct.

[0004] When the above device is in use, after the internal wood ash falls down through the inclined slot, it will still accumulate in the biomass combustion chamber. As more wood ash accumulates and the airflow in the jet pipe enters, a large amount of wood ash is easily discharged from the combustion heat conduction pipe along with the airflow, causing blockage of subsequent equipment and affecting combustion efficiency. Therefore, we propose a biomass power generation device to solve the above problem. Utility Model Content
