PURPOSE:To prevent the explosion of a combustible gas, by taking out a part of a cooling inert gas being circulated, feeding it into a coke charging hopper to mix it with a combustible gas which is generated within the hopper, combining the mixture with a circulating gas, followed by combustion in a combustion chamber. CONSTITUTION:Red hot coke 1 is successively supplied through a charging hopper 2 into cooling chambers 6, 6' etc., where the red hot coke is cooled with a cooling inert gases 5, 5' etc., being circulated through a main body circulating system. In this step. a part of the cooling inert gases 5, 5' etc., being circulated is taken out with a blower 35 and supplied through a bypass pipe 30 into a hopper 2, where it is mixed with a combustible gas G which is generated within the hopper 2. The mixture is sucked with a blower 31, discharged from a high temp. portion of the cooling chamber 6, and combined with the cooling inert gas 5 discharged from a cyclone 8. The mixed gas thus obtd. is led to a combustion chamber 32 together with air 33 to burn the combustible components contained in the mixed gas and allowed to cool, followed by circulation into the circulating system.
