摘要： Calcination apparatus for use in a fluidized-bed installation for burning powdery materials comprises a calcining furnace (7) for calcining the powdery materials and an upper vortex chamber (21) disposed immediately below the furnace (7) which induces swirl in secondary combustion air and discharges it into the furnace (7). A further lower vortex chamber (22) of cyclone type is disposed immediately below the upper vortex chamber (21) and communicates therewith and is arranged, in use, to receive gas from a fluidized-bed furnace (11) through a riser duct (23) and to separate clinker particles from the said gas. A chute (25) is provided for returning the separated clinker particles from the further vortex chamber (22) to the furnace (11).
