PROBLEM TO BE SOLVED: To suppress progress of damage of a supply pipeline for supplying a fluid medium.SOLUTION: A fluidized bed type combustion facility 1 includes a fluidized bed combustion furnace 21 for combusting fuel while fluidizing a fluid medium, and a supply unit 3 for supplying the fluid medium to the fluidized bed combustion furnace. The supply unit 3 includes an air feeding unit 32 for feeding gas transporting the fluid medium, and a flow velocity adjustment unit 34 for adjusting the flow velocity of gas. The flow velocity adjustment unit 34 adjusts the flow velocity of the gas transporting the fluid medium, and suppresses damage of a pipeline 33 in which the fluid medium flows. Progress of damage of the pipeline can be suppressed by reducing the flow velocity of the gas. 【課題】流動媒体を供給するための供給配管の損傷の進行を抑制すること。【解決手段】流動層式燃焼設備１は流動媒体を流動させながら燃料を燃焼する流動層燃焼炉２１と、流動層燃焼炉に流動媒体を供給する供給部３と、を備える。供給部３は、流動媒体を輸送する気体を送風する送風部３２と、気体の流速を調整する流速調整部３４と、を備える。流速調整部３４によって、流動媒体を輸送する気体の流速を調整し、流動媒体が流れる配管Ｌ３３の損傷を抑制する。気体の流速を低下させて、配管の損傷の進行を抑制することができる。【選択図】図１
