Abstract: The waste sands are passed to a calcining chamber having a floor, connecting sidewalls and a top. The floor of the calcining chambers provided with a plurality of vents. The calcining chambers also connected to a separate firebox which produces fluidizing hot gases for fluidizing waste sands within the calcining chamber and forming a fluidized sand bed. The fluidizing hot gases are introduced into the calcining chamber by means of the floor vents. By precisely controlling the temperature of the waste sands within the fluidized bed, a more consistent product is produced while maintaining the temperature of the waste sands below a critical temperature at which the organic binders present on the sand grains would be fused to the waste sand grains.

Abstract: The combustion gas passages leading to a fluidized bed in a hot water or steam boiler are kept free of deposits which might block them by pulses of gas. The gas pulses may be generated from a pressurized reservoir with periodic or aperiodic openings of a valve in a gas line leading from the reservoir to the passages. Where the bottom of a fluidized bed comprises a pair of plates defining a plenum space therebetween and the combustion gas passages define nozzles extending through the plenum space, combustion air may be fed to the nozzles via the plenum space and the cleaning pulses may also be generated from gas supplied to the plenum space.
