Sludge is fed into the incinerator through the feed system in which infrared heat at about 2,500* F. breaks it into small particles for improved combustion. The sludge is moved on the conveyor belt along the chamber where recirculated combustion gases and infrared heat at a temperature in the range of 1,200* to 1,500* F. drives off all moisture and completely burns all volatile components of the sludge. The chamber is operated under a vacuum to prevent escape of noxious odors. At the discharge end of the chamber and conveyor belt, ash is dumped into the removal system and the combustion gases are directed into the scrubber which cools them, vents them to the atmosphere, and removes solid entrained particles.，下面是Incinerator专利的具体信息内容。
