ABSTRACT OF THE DISCLOSURE Disclosed is a portable waste disposal system that is designed primarily for use in marine craft, mobile homes, campers or the like. The system comprises a macerator until for converting excrement to a liquified effluent, and an incinerator unit for incinerating the effluent. The macerator unit comprises a holding tank which receives the waste material from a toilet. When the level of the excrement within the holding tank reaches a predetermined level, and maintains that level for a predetermined period of time, the system is activated and the excrement from the holding tank is macerated by a macerator and provided to a feed compartment. A circulation pump then pumps the macerated effluent from the feed compartment through a circulation line to the incineration unit. The incineration unit comprises a combustion chamber and an additional feed pump which draws effluent from the circulation line and feeds the effluent into the combustion chamber. A crucible is disposed within the combustion chamber for receiving the effluent fed therein. A burner is provided which introduces a high temperature flame into the combustion chamber to incinerate the effluent in the crucible. The crucible is elevated from the floor and spaced from the walls of the combustion chamber so that the flame from the burner fills the entire combustion chamber and heats the crucible on all sides. The effluent within the crucible is incinerated until all of the liquid is vaporized and the remaining solid waste material is reduced to a fine ash. The fuel for the burner is reguinted by a pair of fuel valves, one of which is cycled to maintain the temperature of the exhaust gases from the combustion chamber within predetermined limits. In addition, the entire incineration operation is conducted at a sufficiently elevated temperature so that no offensive odor is created. A pot rotator motor is also provided for rotating the crucible after the incineration cycle is complete to dump the remaining ash material to the floor of the com- bustion chamber. A convenient ash removal duct is provided at the rear of the incineration unit for removing accumulated waste material. The incinerator unit also includes a novel cooling system for dissipating the heat from the combustion chamber, and cooling various critical components to insure the proper operation of the system. The entire system is operated under the control of a solid state control circuit which continuously monitors the system to insure that it is operating within certain critical parameters. As a safety precaution, if various positive checks are not confirmed, the control unit automati- cally shuts down the system, thus eliminating the possibility of an accidental fire.
