ABSTRACT:
A refuse recycling system which recycles municipal waste as energy, includes a shredder for shredding the waste and removing rejects via a feed pipe to a circulating fluidized bed reactor, the reactor producing flue gases. The reactor includes a side dense fluidized bed situated on the wall of the reactor which is provided with the feed pipe, the side dense fluidized bed extracting non-fluidizable heavy elements and transporting them to a coarse-particle sorter apparatus via an extraction duct disposed at a base of the side dense fluidized bed. At least a portion of the rejects from the shredder is fed into the coarse-particle sorter apparatus. The coarse-particle sorter apparatus cools the elements and extracts non-fluidizable inert matter from the elements, the remaining matter being fed back into the reactor. A module for recovering energy and for treating the flue gases output by said reactor is connected downstream from the reactor.
