Description

Technical Field

[0001] The utility model relates to the technical field of biomass hot blast stoves, and more particularly to a high-efficiency biomass hot blast stove. Background Art

[0002] Biomass hot air furnace is a device that uses biomass energy such as sawdust, straw, wood chips, etc. to generate hot air. It is green, environmentally friendly, and energy-efficient.

[0003] Conventional biomass hot air furnaces tend to produce a large amount of smoke during operation, and these fumes are often difficult to be discharged from the inside of the device to the external environment in a timely and effective manner. This situation not only leads to a decline in the quality of the surrounding air, but may also have an adverse effect on the health of the operators. In addition, due to the poor discharge of smoke, the combustion efficiency may be affected, making it impossible for the fuel to be fully burned, thereby reducing energy utilization. On the other hand, the design of existing hot air furnaces is usually relatively simple, and its adaptability to different types of biomass materials that need to be processed is poor. When users put various types of combustible objects into the equipment for heating or conversion, if there is a lack of targeted design to optimize the combustion process, it is difficult to achieve the best combustion effect. This not only extends the time cost required to complete the same task, but also means that more raw materials are wasted and their due value is not brought into play.

[0004] Therefore, in order to solve the above problems, the present application provides a high-efficiency biomass hot air furnace. Utility Model Content
