PCT No. PCT/FR88/00203 Sec. 371 Date Dec. 20, 1988 Sec. 102(e) Date Dec. 20, 1988 PCT Filed Apr. 26, 1988 PCT Pub. No. WO88/08502 PCT Pub. Date Nov. 3, 1988.The grate comprises, within its length, two consecutive beds (41, 42) with substantially the same general slope joined together at a point in substantial vertical alignment with the altar wall (7), each bed having its own mobile frame (45d, 46d) with its own control means (45, 46) and its own draft chamber (43, 44) with its own ventilation means. It is therefore possible to adjust the combustion conditions so as to optimize the carbonization mode combustion on the upstream bed (41) and the brasier mode combustion on the downstream bed (42).
