ABSTRACT:
A furnace grate roller, mainly for incinerating refuse, with a tubular casing formed by rings of bars separated by blow gaps of set width, is of conventional structure, comprising a cylindrical cage framework with T-shape cross-section longitudinal members disposed along its generatrices and a casing formed of groups of rings separated by gaps for blowing combustion-supporting air. The rings are segmented into arcuate bars which extend between the longitudinal members. To limit relative movement of the bars while allowing them some play the bars are attached at one end by a notch to the flange of a longitudinal member and are secured in place by bosses on an intermediate member bolted longitudinally to the longitudinal member. The bars have recesses at their end contiguous with the intermediate member into which the bosses are inserted. In this way the bars are attached with limited capacity for movement relative to the roller in the axial, radial and peripheral directions.
