PROBLEM TO BE SOLVED: To provide pressurized fluidized bed incinerator facilities capable of independently exerting a control to keep a flow volume of combustion air supplied to an incinerator to a predetermined volume and a control over devices and pipes provided on an inlet of a compressor of a supercharger, and making equipment instruments constituting the facilities compact.SOLUTION: Pressurized fluidized bed incinerator facilities include: a pressurized fluidized bed incinerator 1; a supercharger 2 including a turbine 2a and a compressor 2b; a blower 49_1 supplying combustion air to the pressurized fluidized bed incinerator 1 at start of combustion of the pressurized fluidized bed incinerator 1; and a supercharger air bypass valve CV3 passing the discharged air from the blower 49_1 from an air inlet to an air outlet of the compressor 2b at the start of the combustion of the pressurized fluidized bed incinerator 1, and circulating a part of the combustion air supplied from the compressor 2b to the pressurized fluidized bed incinerator 1 from the air outlet to the air inlet in response to a pressure at the air outlet after the pressure at the air outlet is higher than that at the air inlet after the start of the combustion of the pressurized fluidized bed incinerator 1. 【課題】焼却炉へ供給する燃焼空気の流量を所定量に保つ制御と、過給機のコンプレッサ入口側に設けられる機器や配管の制御とを独立に行うことができ、かつ、設備を構成する設備機器をコンパクトにすることが可能となる加圧流動焼却炉設備を提供する。【解決手段】加圧流動焼却炉１と、タービン２ａと、コンプレッサ２ｂと、を有する過給機２と、加圧流動焼却炉１の燃焼開始時に、燃焼空気を加圧流動焼却炉１に供給する送風機４９＿１と、加圧流動焼却炉１の燃焼開始時に、送風機４９＿１からの吐出空気をコンプレッサ２ｂの空気入口側から空気出口側へと通し、加圧流動焼却炉１の燃焼開始後に、空気出口側の圧力が空気入口側の圧力より大きくなった後、空気出口側の圧力に応じて、コンプレッサ２ｂから加圧流動焼却炉１に供給される燃焼空気の一部を空気出口側から空気入口側へと循環させる過給機空気バイパス弁ＣＶ３と、を備える。【選択図】図１
