The paper discusses pilot scale studies of closed-loop fly ash sluicing. Chemicals leached from fly ash in wet sluicing systems can cause scaling of equipment if the sluice water is recycled. A 50 gpm (190,000 cu cm/min) pilot unit was tested at two power plants to evaluate closed-loop operation, with and without sluice water treatment. An ash sluice computer process model was developed and proved accurate in predicting the chemical composition and potential for scale formation in the pilot unit.
