The technical key points of the utility model are as follows: the formula of the biomass fuel is semi-gasified and combusted: different biomass fuels to be combusted are mixed according to a certain proportion and then are fed into a feed bin, semi-gasification is carried out under the temperature condition of 60-180 DEG C, and then volatile gas and residues (mainly fixed carbon) are generated and are respectively combusted. The biomass fuel is an original ecological biomass fuel with irregular shape, length, width and height less than or equal to 30cm. The biomass fuel bin is positioned at the upper partof the solid-state combustion chamber in the device. And the biomass volatile gas is connected with the two combustion chambers of the remainder (mainly fixed carbon). The gas combustion chamber is located at the bottom 31 of the pipeline where flue gas flow in the solid combustion chamber rises first and then sinks for ignition. Compared with an existing biomass particle burner, the biomass particle burner has the advantages of being low in construction cost and modulation cost, saving energy and labor cost, and suitable for intensive modulation equipment for different types of metal heat dissipation pipes.
