Abstract
Et ristelement (1, 2) for en rist i et forbrenningsanlegg oppviser på ristelementhodet (7), på undersiden av dette, henholdsvis på ristelementfoten (8) nedover åpne utsparinger (10), som utgjør luftutløpsåpnlnger for primæriuften som tilføres nedenfra. På hver bakre ende (9) av ristelementene er det anordnet faststående rensefremspring (11) tilsvarende antall utsparinger (10), og som med sin tverrsnittsform, med unntak av den nødvendige bevegelsesklaring, er tilpasset tverrsnittsformen til utsparingene (10). Rensefremspringene (11) befinner seg i bevegelsesområdet til det overliggende ristelementet og er i det minste på den enden som trenger inn i utsparingen (10) utført avsmalnende. For å unngå for stor slitasje kan hvert ristelement (1, 2) på ristelementfoten (8) ha et belegg (14) av slitesterkt materiale.A grate element (1, 2) for a grate in a combustion plant exhibits on the grate element head (7), on the underside thereof, respectively, on the grate element foot (8) downwardly open recesses (10), which constitute air outlet openings for the primary air supplied from below. At each rear end (9) of the grate elements there is provided a fixed cleaning projection (11) corresponding to the number of recesses (10) and which, with their cross-sectional shape, with the exception of the necessary movement clearance, is adapted to the cross-sectional shape of the recesses (10). The cleaning projections (11) are located in the range of motion of the overlying shaking element and are at least at the end which penetrates into the recess (10) being tapered. To avoid excessive wear, each grating element (1, 2) of the grating element foot (8) may have a coating (14) of durable material.
