Abstract: This invention is directed at an infectious waste incinerator system using primary and secondary combustion chambers to reduce the waste to gaseous and particulate matter. Which is passed through a waste heat recovery boiler reduces the temperature of the gaseous and particulate matter and send the recovered heat to pipes. The cooled gaseous and particulate matter is passed to a baghouse packed-bed scrubber where the gaseous and particulate matter is further cooled and diluted. The gaseous and particulate matter is then passed to the lower end of a packed-bed scrubber when it is passed to a treatment tank where it is subjected, in a neutralizing compartment, to a hydroxide and is also surface skimmed. The skimmed material is passed through a filter system and then returned to the treatment tank. The gaseous treated material is pumped back into the packed-bed scrubber and then out an exhaust stack.
