A grid (2) for a solid fuel boiler is provided with a fixed bed (35) equipped with elongate openings (36) for the passage of the cinders and extending around arcs having a common center (37). Inside these openings (36) are arranged riddle pins (38) which are free to move in the longitudinal direction of said openings (36). The riddle pins (38) are carried by two pin supports (39, 40) having a star configuration, arranged one above the other and which, by means of a common bar (50), can be pivoted back and forth around a central axis (41). |
