To provide a stocker type refuse incinerator for gasifying and ashing stuff to be incinerated placed on a stoker, while the stuff passes through a drying zone, a combustion zone and an ember combustion zone, and for burning the gasified stuff in a combustion chamber above the stoker, causing the gasifying speed to be low, and suppressing luminous flame formation on the combustion zone and generation of dioxins.
This stoker type refuse incinerator comprises a hopper 11 in which the stuff 10 to be incinerated such as the refuse is thrown, a stoker 12, an ash chute 13, a primary combustion chamber 14 formed in an upper combustion space of the stoker, and a secondary combustion chamber 15 which is continuously provided thereon and has a secondary air supply unit 21. A radiation heat blocking projecting part 18 is provided on the boundary between the primary combustion chamber 14 and the secondary combustion chamber 15, a bypass passage 17a is provided in the secondary combustion chamber 15 from an upper space of the drying zone, and a bypass passage 17b is provided in the secondary combustion chamber 15 from an upper space of the combustion zone 12c.
