摘要： An integrated air separation and oxygen fired power generation system includes an air separation unit (12) and a gas turbine (6) including an air compressor (4) to provide compressed air for the air separation unit (12). The system further includes a gas turbine expander (6) and at least one additional turbine (40) to drive the air compressor (4), as well as at least one combustion unit (22) to provide drive gas for expander (6) and additional turbine(s). A portion (18) of oxygen produced by the air separation unit (12) is delivered to the combustor(s) (22) to facilitate production of drive gas for use by the expander and additional turbine(s). Turbine inlet temperatures are controlled by recycling water or steam to the combustor(s).

摘要： Methods and apparatus for combustion of a hydrocarbon fuel in a combustion chamber of a furnace or boiler are presented, the combustion normally using only air as an oxidant, part of the air entering the combustion chamber through one or more burners, and a remaining portion of air entering the combustion chamber at a plurality of locations downstream of the burners. The methods comprise injecting oxygen-enriched gas through a plurality of lances into the combustion chamber at a plurality of downstream locations, the oxygen-enriched gas injected at a velocity ranging from subsonic to supersonic, and the oxygen-enriched gas being present in an amount sufficient to provide an oxygen concentration of no more than 2% on a volume basis greater than when air is used alone as oxidant.
