IMPIANTO PER LA RIMOZIONE DI CENERE

In the back-pass of a steam generator, hot fly ash collects at a station. At the station to which the ash gravitates, a liquid bath receives the ash. Nozzles are arranged within the liquid receiving the ash to urge the material into a mechanical grinder in which the ash is reduced for ultimate disposal. The bottom of the collecting receptacle (15) is formed into a series of steps (18,19,20). The fly ash thrown into the body of water (16) gravitates to all the steps. A set of nozzles is mounted above each step to direct purging jets of water over the surface of the steps. These nozzles flush, scour, or purge the solid material on the steps toward the lowest position (21) on the floor of the structure.
