Abstract
In order to create a thrust grating cooler whose system for delivering the cooling air to the individually aerated, reciprocally movable grating plate carriers manages without flexible cooling air hose conduits that are susceptible to wear, at least one cooling air channel is provided that moves together with the C-push frame which carries the movable grating plate carriers. The cooling air channel is mounted at the underside of the C-push frame either transversely or parallel with respect to the longitudinal axis of the cooler. The air entry end of the cooling air channel that is co-moved together with the C-push frame is connected to a stationary cooling air delivery nozzle by means of a seal. A plurality of rigid connecting channels branch off from the cooling air channel to the movable grating plate carriers and supply both the carriers and the movable perforated grating plates that are secured thereon with cooling air. In an embodiment, the C-push frame itself is the cooling air channel and is connected directly to the movable grating plate carriers.
