Claim:
A vertical refuse incinerator for incinerating industrial wastes, including medical wastes, and general wastes, comprising: an incinerator body having a funnel-shaped lower side wall, a flame zone, a refuse layer, a glow layer and an ash layer being formed in this order inside the incinerator body from top to bottom at the time of combustion; an exhaust gas mixing device for spinning combustion gas that is made of a refractor, that is provided above the incinerator body and that has a plurality of secondary air blow holes for supplying secondary air for re-combustion formed therein, at least a part of the air blow holes being opened toward the flame zone in an upper portion of the incinerator body; a re-combustion chamber placed on the exhaust gas mixing device; a cooling casing covering the exterior of the funnel-shaped side wall; a plurality of primary air nozzles supplying primary air for combustion that are introduced into the incinerator body; a casing that is provided for the ash layer below the incinerator body and that houses retractable refuse supporting means and a closable bottom ash discharge plate disposed below the refuse supporting means with a clearance interposed between the refuse supporting means and the bottom ash discharge plate; and an air duct supplying air for final burning that is incorporated into the casing, wherein, at the time of discharging bottom ash, the refuse supporting means is projected into the ash layer so as to support the load of refuse and bottom ash deposited in the incinerator body, then the closed bottom ash discharge plate is opened so as to discharge the bottom ash retained between the refuse supporting means and the bottom ash discharge plate, followed by closing the bottom ash discharge plate, and then the refuse supporting means are retracted; wherein the refuse supporting means comprises a supporting means body formed by arranging side by side a plurality of supporting rods in a fitting frame or two of said supporting means bodies in which said supporting means bodies are placed facing each other such that the supporting rods are opposed to one another; wherein cooling means for cooling the supporting means body or bodies with a cooling fluid and an external driver for retractable driving the supporting means body or bodies are provided; and wherein the external driver is provided with a supporting means detector comprising pressure detection means and position detection means.
