Abstract

A grate for a firing plant, having at least one grate track with a plurality of fixed and moving rows of grate-lining units, which rows alternate in the longitudinal direction, are bounded on both sides by side walls and are provided with cooling passages as well as with feed and discharge lines. The grate-lining units are connected at their rear end to a fixed or movable grate-lining bearer and rest with their front end on the following grate-lining unit, and the cooling passages being arranged essentially transversely to the longitudinal direction of the grate. The cooling passages are tubes arranged in a meander shape and integrally cast in the grate-lining units and whose spacing is adapted to the thermal loading on the grate-lining units. The tube spacing preferably decreases from the rear end to the front end of the grate-lining unit.
