NOVELTY - A biomass carbonization associated gas oxidized residual heat recycling process comprises starting burning of liquefied gas, and oxidizing biomass carbonization associated gas and recycling residual heat, where liquefied gas is mixed with air in mixed burner of biomass carbonization associated gas oxidized residual heat recycling device and are fully burned so as to provide energy of starting biomass carbonization associated gas oxidized residual heat recycling system. The residual heat is recycled in biomass carbonization associated gas oxidized residual heat recycling device.    USE - Method is used for biomass carbonization associated gas oxidized residual heat recycling process.    ADVANTAGE - The method uses high-temperature thermal countercurrent reversing oxidation in biomass carbonization associated gas oxidized residual heat recycling device, thus automatically and fully oxidizing biomass carbonization associated gas.    DETAILED DESCRIPTION - The biomass carbonization associated gas oxidized residual heat recycling process comprises starting burning of liquefied gas, and oxidizing biomass carbonization associated gas and recycling residual heat, where liquefied gas is mixed with air in mixed burner of biomass carbonization associated gas oxidized residual heat recycling device and are fully burned so as to provide energy of starting biomass carbonization associated gas oxidized residual heat recycling system. The biomass carbonization associated gas oxidized residual heat is recycled in biomass carbonization associated gas oxidized residual heat recycling device. The recycling device uses high-temperature thermal countercurrent reversing oxidation to performing automatic high-temperature thermal countercurrent reversing full oxidation on biomass carbonization associated gas flowing through internal of the device; and uses heat energy released in oxidation process to maintain energy consumed in oxidization of associated gas as well as provide residual heat to external.
