ABSTRACT:
A stoker consisting of a support frame, a first plurality of longitudinally spaced sets of grates mounted on the support frame, a second plurality of longitudinally spaced sets of grates mounted on the support frame, each set of the second plurality of sets of grates being interposed between the set of the first plurality of sets of grates and another set of grates, each of the sets of grates consisting of a plurality of transversly spaced grates, each of the grates having an underside surface for seating the grates and an upper surface for supporting a grate of a longitudinally successive set of grates, each transversely successive pair of grates having laterally projecting, overlapping flanges providing a tortuous air passageway between such successive pair of at least one each of the flanges terminating at a point disposed in spaced relation to the underside surface of the grate to provide a substantially longitudinal air passageway between transversely successive grates, and means for reciprocating the second plurality of sets of grates relative to the first plurality of sets of grates.
