To provide a carbon dioxide recovery facility capable of efficiently recovering carbon dioxide from a carbon dioxide emission source.SOLUTION: A carbon dioxide recovery facility 100 includes: a heater 20 into which a first material containing CaCO3 is introduced, and in which a carbon-containing fuel is burned using a high-oxygen concentration gas having a higher oxygen concentration than air to pyrolyze CaCO3, thereby generating a first gas containing CO2 and a solid containing CaO; a reactor 40 in which at least a part of the solid containing CaO generated in the heater 20 is brought into contact with a CO2 containing exhaust gas to produce CaCO3 and produce an exhaust gas and a second gas having a lower CO2 concentration than that of the first gas, while being cooled by a cooling part 41; and a conveyance path B for introducing the solid containing CaCO3 generated in the reactor 40 into the heater 20.SELECTED DRAWING: Figure 1
【課題】二酸化炭素排出源から二酸化炭素を効率よく回収することが可能な二酸化炭素の回収設備を提供すること。【解決手段】二酸化炭素の回収設備１００は、ＣａＣＯ３を含む第１原料が導入され、空気よりも高い酸素濃度を有する高酸素濃度ガスを用いて炭素含有燃料を燃焼してＣａＣＯ３を熱分解し、ＣＯ２を含む第１ガスとＣａＯを含む固形分とを生成する加熱装置２０と、冷却部４１で冷却しながら、加熱装置２０で生成したＣａＯを含む固形分の少なくとも一部とＣＯ２を含む排ガスとを接触させて、ＣａＣＯ３を生成するとともに排ガス及び第１ガスよりもＣＯ２濃度が低い第２ガスを生成する反応装置４０と、反応装置４０で生成したＣａＣＯ３を含む固形分を加熱装置２０に導入する搬送路Ｂと、を備える。【選択図】図１
