Claims11
An external-reheat gas turbine system, comprising:
- a compressor;
- an expander;
- an air heater disposed between the compressor and the expander;
- a combustor disposed between the compressor and the expander;
- a fuel heater coupled to the air heater via a return conduit;
- a boiler disposed between the compressor and the expander;
- a heat recovery steam generator (HRSG) having an economizer discharge that produces feed water, the HRSG coupled to and configured to supply the feed water to the boiler;
- a conduit, including chargeable air supply to the expander, in thermal communication with the boiler and the air heater;
- an external free heat source coupled to the boiler;
- and
- a steam turbine coupled to the HRSG and the fuel heater, wherein the fuel heater is configured to supply spent steam to the steam turbine.
