<P>PROBLEM TO BE SOLVED: To provide a combustion method and device for wet waste capable of causing autogeneous combustion of the wet waste without supplying auxiliary fuel, and capable of reducing an operation cost. <P>SOLUTION: The combustion device for wet waste is provided with a combustion furnace 21 forming a fluidized bed 24 to carry out combustion of inflammable solid components, a partial gasification furnace 22 forming a fluidized bed 32 to carry out drying and partial gasification of the inputted wet waste 27, a hot cyclone 29 separating a bed material from exhaust gas from the combustion furnace 21 and supplying it to the partial gasification furnace 22, a regenerative heat exchanger 30 carrying out heat exchange between air and the exhaust gas separated from the bed material to produce high temperature air for fluidization to be guided to the combustion furnace 21 and the partial gasification furnace 22, a combustor 36 guiding high temperature gas obtained by burning inflammable gas to the combustion furnace 21, and a return pipe 21a returning the inflammable solid components to the combustion furnace 21 along with the bed material. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
