Abstract
A system for disposing of sludge by using the sludge as a primary source of fuel for its disposition by combustion thereof in which a mass of liquified sludge is processed to reduce the solids to a predetermined size for use as the fuel and concurrently separating a substantial portion of the contained liquid, delivering the processed solids and liquids to a combustor for converting the solids to ash and converting the liquids to vapor, introducing ambient air to the combustor to support combustion of the solids while employing a portion of the ambient air to the combustor for removing the vapor at a temperature below the temperature at which the solids are reduced to ash, utilizing a portion of the vapor removed from the combustor to initiate vaporization of the liquid in the mass of liquified sludge being processed initially, using a part of the removed vapor to enter into a heat exchange relationship with the ambient air prior to its being admitted to the combustor, and releasing excess vapor to the ambient atmosphere at a temperature for sanitizing the released vapor to the ambient atmosphere.
