Abstract
Disclosed is a method for enhanced fuel combustion to maximize the capture of by-product carbon dioxide. According to various embodiments of the invention, a method for combusting fuel in a two-stage process is provided, which includes in-situ oxygen generation. In-situ oxygen generation allows for the operation of a second oxidation stage to further combust fuel, thus maximizing fuel conversion efficiency. The integrated oxygen generation also provides an increased secondary reactor temperature, thereby improving the overall thermal efficiency of the process. The means of in-situ oxygen is not restricted to one particular embodiment, and can occur using an oxygen generation reactor, an ion transport membrane, or both. A system configured to the second stage combustion method is also disclosed.
