Description

Technical Field

[0001] The utility model relates to the technical field of fuel boiler equipment, in particular to a horizontal biomass fuel boiler. Background Art

[0002] A biomass fuel boiler is a device used to burn biomass. It can make full use of wood, straw, sawdust, etc. for combustion, and in turn convert the high-temperature heat energy generated by the combustion into clean energy. Different from traditional coal boilers, the use of biomass fuel boilers can avoid excessive development and combustion of coal resources, reduce pollution to the environment, and help reduce damage to the environment.

[0003] However, at present, the biomass fuel inside the biomass fuel boiler cannot be fully and completely burned, and the ash generated is easily accumulated at the bottom and is not easy to remove and discharge. The boiler itself is difficult to disassemble and the operation is complicated. It often takes a lot of manpower and material resources to dismantle the entire device for cleaning. In addition, the exhaust gas generated by combustion will also be mixed with a large amount of dust, which will be directly discharged into the air and will affect the surrounding environment.
