UTILISATION OF SUBMERGED SCRAPER CONVEYORS
The ash moves with the chain to the transition point where the travel direction changes from horizontal to inclined (Fig 11). At this point the ash load is "fluidised" and the bulk density drops. The ash tumbles/flows backwards, down the submerged portion of the dewatering slope, to its natural angle of repose in the water as indicated in Fig 11.
