Zusammenfassung:A circulating fluidized bed boiler (a CFB boiler) that supplies fuel into a furnace 11 in which a fluid material is flowing to combust the fuel comprises carbon-free fuel supply units 16A-16D that supply ammonia or hydrogen into the furnace 11 as a carbon-free fuel that does not contain carbon. Carbon-free fuel supply unit 16A supplies the carbon-free fuel to a wind box 122, carbon-free fuel supply unit 16B supplies the carbon-free fuel to a fluidized bed A, carbon-free fuel supply unit 16C supplies the carbon-free fuel to the surface of the fluidized bed A, and carbon-free fuel supply unit D supplies the carbon-free fuel to a free board B.
