Abstract
An improved grate block includes a blow-out channel terminating at a blow-out opening through the face of the block, the opening having pre-determined dimensional relationships with respect to the size of the front face of the block. The ratio of the width to the height of the front face is smaller than the ratio of the width to the height of the blow-out opening, and one-half the area of the front face is between 20 and 40 times larger than the cross-sectional area of each blow-out opening. Additionally, the blow-out openings are arranged above the horizontal center line and laterally spaced from the vertical center line through the front face, the channel sloping at an angle relative to the upper surface of the grate block which lies between about 15.degree. and about 25.degree..
