Sludge coal water slurry (SCWS) is prepared by replacing part of the coal with sludge, . There are two primary advantages of using municipal sludge to prepare SCWS. One is to decrease the expensive subsequent treatment of sludge, and the other is to reduce the water consumption in SCWS owing to the high water content of the sludge.
