An Atomized Spray Vortex Incinerator for Burning Dilute Siudge*

An incinerator is described for the disposal of solids resulting from the treatment of shipboard sanitary and culinary wastes_ The incinerator is based on the vortex flow principle_ Sludge is atomized and sprayed into the hot burner gases by a non-clogging pneumatic nozzle. In order to meet stringent weight and size specifications, the incinerator walls are constructed en­ tirely of metal and are cooled by passing ambient air through passages in the walls. The incinerator operates at temperature levels high enough and with sufficient sludge residence time to eliminate odors_ The design is capable of handling sludge flow rates in the range from about 50 to 300 lb/h.
