As a renewable and environmentally friendly resource, with the increasingly serious environmental problems, the treatment of biomass has become relatively important. Traditionally, biomass is generally treated by incineration or landfill. This type of treatment is not only an extreme waste of resources but also pollutes the environment. Therefore, biomass pressurized pyrolysis equipment came into being.

[0003] For example, a biomass pyrolysis furnace with Chinese patent number CN218951324U is provided. In the utility model, a driver is arranged at the top of the furnace body and a driving rod is arranged at the power output end of the driver. A stirring blade is arranged on the surface of the driving rod. A pull box is arranged in the furnace body and the stirring blade is in contact with the bottom of the pull box. A filter plate is arranged at the bottom of the pull box so that carbon slag of a suitable size can fall into the bottom of the furnace body. However, the utility model only has a structure for cleaning the carbon slag at the bottom of the furnace body, and lacks a cleaning mechanism for the inside of the furnace body. At the same time, the driving device is located inside the pyrolysis furnace body, which increases the difficulty of heat dissipation and maintenance, and is not conducive to user use. Therefore, a pressurized pyrolysis device for biomass combustion is proposed to solve the above problems. Utility Model Content
