Abstract: A method for supplying combustion air in a vertical incinerator according to one embodiment of the present invention is such that during incineration treatment by the vertical incinerator 1, a supplied amount of combustion air a is controlled in such a manner as to be 0.2 to 0.8 times as much as a theoretical air amount that is necessary to completely combust waste R in deposit layers, and the combustion air a is supplied in such a manner as to reduce oxygen in the combustion air a from a lower portion to an upper portion of the deposit layers.

Abstract: In a vertical refuse incinerator for incinerating wastes according to the present invention, an incinerator body 1 is made up of an upper cylindrical part CP and a lower funnel part FP covered by a cooling case, and an exhaust gas mixing device 4 promoting the mixing and secondary combustion of combustion gas stream CG is provided between a flame zone FZ and a re-combustion chamber 45. On the other hand, completely incinerated bottom ash is discharged below the incinerator body 1 by the opening and closing operations of a bottom ash discharge device DD by cooled refuse supporting means RS and bottom ash discharge plates 35.
