Abstract: Rotary combustor and seal assembly therefor. A rotary combustor includes a shroud ring encircling an inlet opening of a rotatable kiln in which municipal waste is burned, the waste heat being used to generate electricity. The kiln includes a plurality of parallel heat transfer tubes arranged in spaced parallel circular array. The end portions of the tubes terminate in a ring header or plenum that surrounds the shroud ring, so as to define an annular gap between the ring header and shroud ring. A plurality of blocking members are connected to the kiln and interposed between the plenum and the shroud. The shroud and the blocking members cooperate to seal the gap. Moreover, a portion of each blocking member extends over a predetermined portion of a respective one of the tubes and over a predetermined portion of the plenum to protect the plenum and the pipes from impact damage by the municipal waste.
