摘要:
A rotary combustor is disclosed in which a plurality of tubes connect a first header to a second header, and in which the first and second headers have a plurality of baffles dividing them into a plurality of chambers. In accordance with the invention, a branch pipe is located at the extreme end of a first of the chambers for admitting fluid to the first chamber, such that the fluid flows through a first set of tubes to a second chamber and then through a second set of tubes and is returned to another chamber and exits through a second branch pipe disposed at an extreme end of the chamber. The structure made in accordance with the present invention exhibits a relative flow pattern between the chambers that is a counterflow, thereby improving the performance of the combustor. preferably, the tubes are grouped in plurality of pairs of tubes, and the chambers include relatively smaller chambers and relatively larger chambers. In one preferred embodiment, the combustor has an input end and a discharge end, and the relatively larger chambers are disposed at the input end and the relatively smaller chambers are disposed at the discharge end. Preferably, the headers are toroidal ring headers.

The invention concerns a grate bar for a grate tumbler of a tumbler grate of a trash incineration installation or similar combustion facility with a base rod showing an outer rod surface and an inner rod surface, as well as side surfaces, a head surface and a foot surface, the cross-section form being T-shaped with a cross rod (15). The invention also concerns a grate tumbler for the tumbler grate of a trash incineration installation or the like with a hollow shaft and a cylindrical carrier construction, with grate-bar carriers resting upon the carrier construction and grate bars mounted upon the carriers, while the grate bars are mounted upon the grate bar carriers (8) in such fashion that the slit (25) between adjacent grate bars (11) is no greater than 1 mm in width on the combustion-chamber side.

A grate assembly (10) for a gasifier for gasifying carbonaceous material producing ash includes an upper rotatable grate component (11) and a lower rotatable support structure (12) fastened to the upper rotatable grate component (11) by a plurality of removable fasteners (15) acting to prevent vertical displacement of the upper rotatable grate component (11) and the lower rotatable support structure (12). The lower rotatable support structure (12) is configured to be drivingly rotated about a common vertical axis of rotation (21) shared with the upper rotatable grate component (11). The assembly (1) further includes at least two key torque transmitters (16) spaced angularly relative to the common axis of rotation (21) and engaging the upper rotatable grate component (11) and the lower rotatable support structure (12) to transfer torque from the lower rotatable support structure (12) to the upper rotatable grate component (11) when the lower rotatable support structure (12) is driven.
