Power generation system including a gas generator combined with a liquified natural gas supply

A method of combining a gas generator with a liquefied natural gas (LNG) supply source in a power generation system, the method comprising:

• supplying a LNG stream from the LNG supply source to the system;
• supplying an oxygen stream and a gaseous hydrocarbon fuel stream to an inlet of the gas generator to produce a combustion product stream comprising steam and carbon dioxide;
• delivering the combustion product stream to a turbine section disposed downstream from the gas generator;
• expanding the combustion product stream in the turbine section;
• and
• exchanging heat between the LNG stream and at least one other stream flowing within the system, via a heat exchange section disposed between the LNG supply source and the gas generator, wherein at least a portion of the LNG stream is converted to the gaseous hydrocarbon fuel stream prior to delivery of the gaseous hydrocarbon fuel stream to the gas generator and the at least one other stream is cooled to a selected temperature.

A power generation system comprising:

• a means for receiving and combining an oxygen stream and a gaseous hydrocarbon fuel stream to generate a combustion reaction that forms a combustion product stream comprising steam and carbon dioxide;
• a means for receiving and expanding the combustion product stream formed from the combustion reaction;
• a liquefied natural as (LNG) supply source to provide an LNG stream within the system;
• and
• a means for facilitating heat exchange between the LNG stream and at least one other stream flowing within the system such that the at least one other stream is cooled to a selected temperature and at least a portion of the LNG stream is converted to the gaseous hydrocarbon fuel stream prior to being combined with the oxygen stream to generate the combustion reaction.
