PURPOSE:To realize effective chemical reactions of various kinds of substances with a simplified structure in which partition walls are provided in a vertical cylindrical tank to form two fluidized bed compartments and particles are circulated in both the fluidized beds. CONSTITUTION:The two large partition walls 3a and 3b are provided in the vertical cylindrical tank 1 and also the small partition wall 4 is provided between the large partition walls to divide the tank 1 into four compartments I to IV. The lower part of the compartments I and III is provided with the porous bed 5 for the dispersion of fluidizing gas and each compartment is packed with the particles 2 which are circulated in the arrow direction by fluidizing gas supplied from the nozzles 8 and 9 into between the compartments I and III. The particles 2 between the compartment I and III move through the compartment II and IV to the lower and upper through holes with the inclined plates 7a and 7b, and raw materials and combustion gas for gasification enter the respective charging openings 10 and 11 formed gas and combustion exhaust gas go out of the respective outlets 12 and 13. |
