Abstract (en)

[origin: EP0757206A2] The grid plates (3,4) have openings or slots (8) for feeding in primary air. The back ends of the plates are connected to a fixed or movable support (6). The front ends of the plates rest on the adjacent grid plate. The grid plates in one row are joined by connections so that adjacent plates can move to a limited extent in a longitudinal direction, and can swivel in relation to their support. The undersides of the grid plates have cooling ducts (9) between the openings or slots and formed by the grid plates themselves and by the hollow profiles (10) on the grid plates. The cooling ducts run parallel with the grid longitudinal direction and are in series or sinusoidal.
