Zusammenfassung:	A system and method (100) for treating, injecting and co-combusting sludge i n a municipal waste or other combustor is disclosed. The system includes a sludge receiving and treatment module (200) and a sludge injection and combustion module (300). The sludge is received and stored in one or more storage hoppers (1) where it is first diluted with a liquid (3) and subsequently mixed (13) to a desired homogeneous consistency suitable for pumping. The high liquid content sludge is then pumped (16) to a furnace injection nozzle (19) where it is preferably atomized with steam (29) and sprayed into the combustion zone of the furnace (20). The disclosed system a nd method increases sludge moisture content and controls the solids content of the sludge to control furnace temperature.
