A fluidized bed reactor (1), suitable for recycling a fluidization gas containing in suspension particles of solid material, has a gas distributor (13) consisting of a double-coned body or of a series of concentric cones provided on their lateral surfaces with ribs or fins (18) forming gas inflow channels (19) shaped in such a way and with such an inclination as to allow the passage of the solid particles dragged along by the gas flow, and such as to hinder the outflow of the solid material that has been fluidized, when the flow of the gas is interrupted. |
