Modelling of feed distributor at coal washeries

Dec 01, 2006· The ROM coal and water are then mixed inside the vessel and split to individual modules. With each outlet from the distributor feeding a de-sliming screen and then to a DM cyclone, the first indicator of distributor performance is generally the large differences in bed height on each de-sliming screen, that is clearly visible to the naked eye.

feed coal is reduced from 42% to 34% and to 24% respectively. Total project cost of such plant including cost of coal washery and AFBC for using washery rejects at ash content at 42%, 34%, 24% is likely to be cheaper by 5%, 8% and 10% respectively. Generation of 15 to 18 MWe by AFBC is an extra benefit. Larger gains may be
