A dual-bed decoupling combustion technology was proposed to burn the industrial biomass residues rich in water and N generated in various light industry processes. The necessity and feasibility of this technology was investigated through experiments and process simulation by employing the distilled spirits lees to represent the industrial biomass residue. The results showed that in a fluidized bed the higher the water content, the longer the ignition time for the distilled spirits lees. And the combustion is unstable when the water content is higher than a certain value. For high N in feedstuff the NO concentration in the flue gas was found to be higher than 800 mg/m 3 . Burning the fuel via the decoupling combustion realized stable combustion and reduced the NO emission by more than 50%. The distilled spirit lees were found to be easier to burn out than the rice husk, and no ash melting and agglomeration were found in the quartz sand fluidized bed running in 500~900°C. The process simulation via Aspen plus demonstrated that the stable autothermal combustion could be realized via the duel bed combustion even for the distilled spirits lees containing water of up to 55%(?).
