Abstract: A fluidized bed system for pyrolysis or incineration of solid wastes is provided. The solids feed is force fed to a fluidized bed apparatus having a conically shaped distributor plate and a first internal chamber above the distributor plate and a smaller second internal chamber connected to the first chamber and positioned directly below the first chamber. Solid waste is fed into the apparatus by a feeder which seals the feeder from the apparatus at a point spaced from hot-zone of the apparatus. The system has fluidizing gas inlets which are designed so that fluidized bed in the first internal chamber is more highly fluidized than the fluidized bed in the second internal chamber. A lock in the second internal chamber permits removal of nonreacted materials without interruption in operation of the system.
