ABSTRACT:
Disclosed is an apparatus for scrubbing combustion gas, the gas being directed downwardly through a first scrubber passage having a first nozzle for feeding a scrubbing liquid that contacts the gas, a first filter material being held within the first scrubber passage and below the first nozzle, the gas being directed upwardly through a second scrubber passage optionally having a second nozzle for feeding additional scrubbing liquid that contacts the gas, and a cartridge for holding at least one second filter material within the second scrubber passage. The cartridge includes a first supply of limestone at least partially submerged in the scrubbing liquid, a supply of the borax above the first supply of the limestone, and a second supply of the limestone above the supply of borax. A reservoir chamber connects bottom extremities of the scrubber passages, the chamber being capable of sealingly retaining a supply of the scrubbing liquid to a sufficient level that gas flowing into the second scrubber passage from the first scrubber passage is required to pass through the scrubbing liquid. A third filter material including charcoal can be provided in the second scrubber passage and above the optional second nozzle, the gas being required to flow through the third filter material. A pump feeds the scrubbing liquid from the reservoir chamber to the first and second nozzles. An ignitor produces secondary combustion of upwardly flowing exhaust gas in an inlet passage.
