Fluidized bed pyrolysis furnace

Abstract

Abstract PROBLEM TO BE SOLVED: To provide a fluidized bed type thermal cracking furnace which can efficiently fluidize and stir a mixture of organic substances different in sizes and specific gravities. SOLUTION: The cross section area S of the fluid bed furnace is made smaller than the lower part S0 of the fluidization part 02 and the cross section area S1 of the gas-flowing part (the free board part) 01. Thus, the superficial velocity at the fluidization part 02 becomes larger than that at the gas-flowing part 01 and the reactive large particles of a large diameter 05 is efficiently fluidized at the fluidization part 02, while the flying particles accompanied by the gas becomes smaller.
