ABSTRACT:
Apparatus for incinerating grease-laden aqueous mixtures includes a burner assembly or having a swirl chamber whereinto the liquid is tangentially fed and swirled. From a nozzle connected to the chamber, a minor fraction of the feed mixture is emitted as a rotating, atomized spray for subsequent ignition. A major fraction of the feed is continuously recycled thereby maintaining a high liquid flow rate through the burner assembly. A system is described for conditioning feed mixtures, and particularly sewage water skimmings of the type derived from a primary sewage treatment operation prior to delivering them to the burner assembly; the system includes means for grinding, heating and settling the materials before incinerating them.
