Abstract

An improved methods and systems are provided for transferring heat in a combustion system. The methods and systems provide for alternately exposing a reducing gas and a gas containing molecular oxygen to an unmixed combustion catalyst to respectively reduce and oxidize the unmixed combustion catalyst. The unmixed combustion catalyst is readily reducible when in its oxidized state and is readily oxidized when in its reduced state. The alternating reduction and oxidation reactions enable the unmixed combustion catalyst to efficiently release heat to a heat receiver in efficient thermal contact with the unmixed combustion catalyst. In most embodiments of the present invention, the unmixed combustion catalyst is in a reactor bed of a combustion system.
