ABSTRACT:
A liquid waste feeding system to be used in conjunction with a solid waste, pyrolytic incinerator. The liquid waste is atomized and injected into the upper end portion of the pyrolysis chamber of the incinerator through a retractable nozzle assembly. The nozzle assembly is automatically extended into the pyrolysis chamber during periods when the liquid waste is to be supplied to the incinerator, and is retracted to a location outside of the chamber when liquid waste is not being supplied. The feed rate of the liquid is controlled by the incinerator stack temperature and modulates between two temperature set points. At the upper set point, the feed rate decreases on temperature rise, which will occur when burning liquids with high BTU values. At the lower set point the feed rate decreases on temperature drop, to insure that minimum combustion temperatures are maintained in order to achieve complete burnout in the incinerator thermal reactor.
