入熱に加呻する方法により利用されて（・た。Now, the coke breeze contained in the circulating gas discharged from the cooling tower (1) is separated from the circulating gas by removing 2 g (2) as in the prior art. The separated coke powder (6) is
Conventionally, coke powder was used by cooling it and then taking it out of the system, or by completely burning the coke powder and adding it to the heat input to the boiler.
