<p>The pusher grate has a grate bar (12) moved forward and backward for producing a feed motion, and a cooling fluid supply line (22) attached to the movable grate bar. The supply line has two line segments (26, 28) that are flexibly connected with each other, where the line segments are rotatably arranged for compensating the forward and backward movement of the grate bar. The line segments are connected with a fluid-sealed joint (36) and/or supply line, where the joint has two angular shaped grate pieces.</p> |
