The infeed grate consists of grate blocks (1) arranged in rows placed side-by-side and extending in the direction of movement of the fuel, said grate blocks being secured mutually overlapping on grate beams (2, 3) inclined downwardly and parallel in said direction, every other of the grate beams (2) belonging to a first set and the remaining grate beams (3) belonging to a second set of grate beams. The two sets of grate beams (2 and 3) and the grate blocks (1) secured thereto are reciprocated in their longitudinal direction in opposite phase by means of drivers (14) fastened to a first restrictedly rotatable shaft (13) engaging with recesses (15) in the lower side of each grate beam (2) of the first set, and other drivers (17) fastened to another restrictedly rotatable shaft (16) engaging with recesses (18) in the lower side of each grate beam (3) of the second set, said shafts (13 and 16) rotating back and forth in opposite phase. |
