This invention relates to a fluidized-bed reactor (1) for the chemical and/or physical treatment of fluidizable substances and to a process herefor. Into the reactor interior (2), process gas is introduced via at least one central tube (3) and fluidizing gas via a tuyère bottom (7). The metallic walls of the central tube (3), of a container (4) connected with the same, and of an annular space (9) provided below the tuyere bottom (7) are provided with a thermal insulating coating (6, 10). |
