STOKER TYPE DUST INCINERATOR AND INCINERATING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an incinerating method and an incinerating apparatus which is a stoker type dust incinerator with a stoker having steps in the dust flowing direction and operates with a primary combustion air fed from a stoker lower part, without depositing molten fly ash to the sides of combustion chambers at the rises of the steps, thereby improving the availability of the incinerator. SOLUTION: Air flowing layers or low temperature boundary films are formed on the sides of combustion chambers at the rises of steps to avoid depositing molten fly ash.
