Abstract
Methods and apparatus are provided for combustion systems wherein fuel may be burned completely with use of air as the oxidant, without the necessity for completely mixing the fuel with the air before, during, or after the combustion process. A bed of readily reducible metal oxide, the reduced form of this metal oxide being readily oxidized, is placed within a combustion system. The air and fuel are contacted with the bed at an elevated temperature, with the metal oxide oxidizing the fuel and being regenerated by the air. In one embodiment, complete combustion of fuel occurs without complete mixing of fuel and air. In other embodiments fuel can be burned with little or no mixing with a the combustion process, or fuel can be burned with little or no mixing with air, before, during, or after the combustion process, thereby avoiding a number of disadvantages of such mixing.
