The grate bar (1) has an upper side (2) and a front surface (3) passing into each other over a curved section (6), and a closure plate (7) arranged below the curved section. The upper side and a rear longitudinal surface (4) pass into each other over another curved section (8), and another closure plate is arranged below the latter curved section, where the plates are arranged at a distance to the sections. An outlet opening (10) is arranged at the upper side for gaseous flow i.e. airflow, that is directed opposite to a lower side (5). Central ribs (11) are connected with the upper side. |
