METHODS AND SYSTEMS FOR HEAT TRANSFER BY UNMIXED COMBUSTION

摘要

Improved methods and systems are provided for transferring heat in a combustion system. The methods and systems provide for alternately exposing a reducing (60) and a gas containing molecular oxygen (88) to an unmixed combustion catalyst (80). The unmixed combustion catalyst is readily reducible when in its oxidized state and is readily oxidizable when in its reduced state. The alternating reduction and oxidation reactions enable the unmixed combustion catalyst to efficiently release heat to a heat receiver (82) 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.
