Abstract
Systems and methods for operating a heating device are disclosed. An oxygen containing stream is first processed to produce an oxygen stream that comprises more than 25 vol. % oxygen. The oxygen stream is then mixed with an air stream to produce a combustion gas stream comprising 21.5 to 27 vol. % oxygen. A fuel is combusted in the combustion gas stream to provide heat for a heating device.
Claims8
A method of operating a heating device, the method comprising:
- flowing a first air stream through one or more oxygen separation membrane modules disposed at a first inlet of the heating device to produce an oxygen enriched stream;
- flowing an additional air stream through a first inlet of the heating device such that the additional air stream and the oxygen stream form a first combustion gas stream;
- flowing a second air stream and the oxygen enriched stream into the heating device counter-currently to each other such that countercurrent sweep of air across a permeate side of the oxygen separation membrane modules is generated;
- mixing the second air stream mixes with the first combustion gas stream to produce an oxygen enriched combustion gas stream;
- and
- combusting a fuel in the oxygen enriched combustion gas stream in the heating device to produce heat.
