<p>PROBLEM TO BE SOLVED: To provide a carbon dioxide recovery method and apparatus which can suppress cost and recover carbon dioxide using a solid fuel.SOLUTION: A carbon dioxide recovery apparatus includes: a combustion furnace 1 which receives the supply of a solid fuel or pyrolysis gas and oxidized metal particles to form a fluidized bed, reduces the oxidized metal particles in the fluidized bed, discharges flue gas generated in the fluidized bed to a supply line as carbon dioxide, and supplies the reduced metal particles and combustion ash generated in the fluidized bed to a metal oxidation furnace 2; the metal oxidation furnace 2 which oxidizes the metal particles supplied from the combustion furnace 1 and brings the combustion ash into a state of being contained in exhaust gas; and separation means 3 which receives the supply of the oxidized metal particles and the combustion ash-containing exhaust gas from the metal oxidation furnace 2 and separates the oxidized metal particles to return them to the combustion furnace 1.</p> |
