Abstract
An oxygen selective ion transport membrane is integrated with a boiler furnace to generate steam and, optionally, high purity oxygen and nitrogen. The heat required to drive the system is obtained by the combustion of an oxygen transported through the oxygen selective ion transport membrane with a high BTU fuel such as methane or natural gas. NO compound formation is minimized either by utilizing a combustion products diluted air/fuel mixture for combustion in the boiler furnace or by limiting combustion to a mixture of oxygen and a fuel.
