PURPOSE:The coke dust which has been collected in the dust collector is combusted in a fluid bed type burner whereby the disposition after coke dust collection is simplified and the recovery of heat in the extinguisher is increased. CONSTITUTION:Coarse coke dust collected in the first dust collector 2 following the cooling oven 1 is fed to the fluid bed type burner 6 where the dust is burned and the circulation gas is utilized on this combustion to control the combustion temperature to the optimum (about 900 deg.C). Then, the coke dust and ash are collected with the sub-collector 12 at the outlet of the burner 6 and fed again to the burner 6 where the coke dust is burned.
