Abstract
A water-cooled firing grate made up of grate bar blocks extending over the width of the grate and each having a plurality of grate bars mounted on a grate bar carrier and interconnected by connecting pieces communicating between meandering shaped channels in the grate bar and a pair of end pieces forming an inlet and an outlet at the outer boundaries of the block and connected to an inlet and an outlet for the cooling water. The pieces are so fixed to the bars that they maintain a clearance between the bars of 1 to 1.5 mm.
