Abstract
A method and apparatus are provided for oxidizing unoxidized fuel in combustion systems in which the air and fuel are not completely and uniformly mixed, the average air fuel ratio being sufficient for complete oxidation, but portions not containing sufficient air for complete oxidation. A bed of a readily reducible metal oxide, the reduced form of this metal oxide being readily oxidized, is placed within the combustion system. The air and fuel are passed through the bed at an elevated temperature, the metal oxide oxidizing those portions not containing sufficient air for complete combustion, and then being reoxidized by those portions which contain more than sufficient air for complete combustion.
