To provide an incinerator plant in which stable combustion is ensured in an incinerator, and production of clinker on an internal wall surface of the incinerator is reduced.
A supply nozzle 6 is provided in a vertical combustion furnace 3 for supplying particulate waste plastic 2, and a transportation piping 20 is connected with the supply nozzle 6 for feeding the waste plastic 2 with air into the furnace, and further a blowoff member 7 is provided on the bottom of the combustion furnace 3. The supply nozzle 6 is located above the blowoff member 7. Hereby, the variation of the amount of the waste plastic 2 supplied into the combustion furnace 3 are reduced and become mild whereby stable combustion is ensured in the combustion furnace 3. Further, since the main stream of combustion gas is caused to flow from upward by the air blown out from the blowoff member 7, the uncombusted waste plastic 2 is prevented from being deposited on the furnace bottom.
