TL;DR: In this paper, a method and apparatus for obtaining from air (2) an oxygen enriched gas mixture containing at least 40 mole % nitrogen is presented, which includes a gas turbine, an oxygen separation unit which is in fluid communication with the turbine air compressor, and means for maintaining a proper mass balance tolerance between the turbine compressor/unit and the turbine energy production unit.
Abstract: This invention comprises a method and apparatus for obtaining from air (2) an oxygen enriched gas mixture containing at least 40 mole % nitrogen The apparatus comprises a gas turbine, an oxygen separation unit which is in fluid communication with the turbine air compressor (28) and means for maintaining a proper mass balance tolerance between the turbine compressor/unit and the turbine energy production unit (26) This invention comprises a method and apparatus for recovering large quantities of an oxygen enriched gas from the volume of a compressed air stream (10) produced by a gas turbine by compensation of the mass loss to the energy production unit section (26) thereof by providing means for maintaining the turbine in proper mass and thermal balance as the turbine is utilized to provide the duty/power requirements of a process which utilizes the oxygen enriched gas stream as a reactant

25 Mar 2013TL;DR: In this paper, a power generation system and method of generating power with reduced NO x emission includes a gas turbine system (15), which includes a compressor (16) and supply a compressed oxidant stream (18) to a combustion chamber (20) and an expander (24) configured to receive a discharge stream (22) from the combustion chamber and generate an exhaust stream (30) comprising carbon dioxide and electrical energy.
Abstract: A power generation system (10) and method of generating power with reduced NO x emission includes a gas turbine system (15). The turbine system (15) includes a compressor (16) configured to receive a feed oxidant stream (14) and supply a compressed oxidant stream (18) to a combustion chamber (20) and an expander (24) configured to receive a discharge stream (22) from the combustion chamber (20) and generate an exhaust stream (30) comprising carbon dioxide and electrical energy. The system (10) further includes an exhaust gas recirculation system (54) configured to generate a recycle stream (52), wherein the recycle stream (52) is mixed with a fresh oxidant (12) to generate the feed oxidant stream (14). The exhaust gas recirculation system (54) includes an exhaust gas recirculation control loop (60) to control a pilot ratio (diffusion to total fuel ratio) based on received feedback related to combustion parameters. The control loop (60) is configured to control the pilot ratio required to keep NO x in its minimum ratios with improved flame stability.

TL;DR: The outer air seal of a gas turbine engine is continuously cooled by compressor discharge air (primary) and a bypass line (secondary) which can be throttled or shut off, augments cooling during high power conditions and is throttled and shut off at reduced power conditions, allowing the casing scrubbed by fan discharged air to shrink and reduce the clearance of the turbine blades.
Abstract: The outer air seal of a gas turbine engine is continuously cooled by compressor discharge air (primary) and a by-pass line (secondary) which can be throttled or shut off, augments cooling during high power conditions and is throttled or shut off at reduced power conditions, allowing the casing scrubbed by fan discharged air to shrink and reduce the clearance of the tips of the turbine blades. The air from the continuous flow (primary) line is routed to the outer air seals in a manner to avoid scrubbing the engine case.
