Claim:
1. An integrated system comprising: a gas turbine system comprising a combustion chamber configured to combust one or more oxidants and one or more fuels in the presence of a compressed recycle stream, wherein the combustion chamber directs a first discharge stream to an expander to generate a gaseous exhaust stream and at least partially drive a main compressor; an inlet compressor configured to compress the one or more oxidants to generate a compressed oxidant stream and direct the compressed oxidant stream to the combustion chamber; and an exhaust gas recirculation system, wherein the main compressor compresses the gaseous exhaust stream and thereby generates the compressed recycle stream; wherein a variable portion of the gaseous exhaust stream is diverted from the exhaust gas recirculation system and combined with the one or more oxidants to form a combined oxidant-exhaust stream that is directed to the combustion chamber, wherein the combined oxidant-exhaust stream has an oxygen component suitable to achieve substantially stoichiometric reaction conditions with the one or more fuels in the combustion chamber; and wherein the combustion chamber is configured to separately receive the combined oxidant-exhaust stream, the one or more fuels and the compressed recycle stream to create reaction conditions in the combustion chamber that are stoichiometric or substantially stoichiometric.
