Abstract

Electrical power systems, including generating capacity of a gas turbine, where additional electrical power is generated utilizing a separately fueled system during periods of peak electrical power demand.

Claims (30)

1. A method of operating a gas turbine energy system comprising:

(a) operating a gas turbine system comprising a compressor, a combustor case, a combustor, and a turbine, fluidly connected to each other;

(b) pressurizing ambient air via a fueled engine driven compression process including using a supplemental compressor driven by a fueled engine;

(c) injecting said pressurized air into said combustor case; and

(d) routing exhaust of the fueled engine downstream the turbine, the fueled engine exhaust bypassing the combustor case.

2. The method according to claim 1 , wherein exhaust from the fueled engine is used to preheat fuel that is fed into the combustor.

3. The method according to claim 1 , wherein exhaust from the separately fueled engine is used to preheat fuel that is fed into the combustor.

4. The method according to claim 1 where all or a portion of the fueled engine's exhaust is diverted to provide heat input to a heat recovery steam generator when the gas turbine is not operating.

5. The method according to claim 1 where all or a portion of the fueled engine's exhaust is diverted to provide heat input to a heat recovery steam generator and/or the turbine when the gas turbine is not operating.

6. The method according to claim 1 where the pressurized air is diverted to provide heat input to a heat recovery steam generator and/or the turbine when the gas turbine is not operating.

7. The method according to claim 1 where the pressurized air is diverted to provide heat input to a heat recovery steam generator and the turbine when the gas turbine is not operating.

8. A method of operating a gas turbine energy system comprising:

(a) operating a gas turbine system comprising a compressor, a combustor case, a combustor, and a turbine, fluidly connected to each other;

(b) cooling gas turbine inlet air using a supplemental refrigeration process driven by a fueled engine; and

(c) injecting exhaust from the fueled engine into an exhaust of the gas turbine.

9. The method according to claim 8 , wherein exhaust from the separately fueled engine is used to preheat fuel that is fed into the combustor.

10. The method according to claim 8 where all or a portion of the fueled engine's exhaust is diverted to provide heat input to a heat recovery steam generator and/or the turbine when the gas turbine is not operating.

11. The method according to claim 8 where is diverted to provide heat input to a heat recovery steam generator and/or the turbine when the gas turbine is not operating.

12. A method of operating a gas turbine energy system comprising:

(a) operating a gas turbine system comprising a compressor, a combustor case, a combustor, and a turbine, fluidly connected to each other;

(b) pressurizing ambient air using a supplemental compressor driven by a fueled engine; and

(c) injecting said pressurized air into a rotor cooling air circuit upstream of a rotor air cooler.

13. The method according to claim 12 , wherein exhaust from the separately fueled engine is used to preheat fuel that is fed into the combustor.

14. The method according to claim 12 where all or a portion of the fueled engine's exhaust is diverted to provide heat input to a heat recovery steam generator and/or the turbine when the gas turbine is not operating.

15. The method according to claim 12 where is diverted to provide heat input to a heat recovery steam generator and/or the turbine when the gas turbine is not operating.

16. A method of operating a gas turbine energy system comprising:

(a) operating a gas turbine system comprising a compressor, a combustion case, a combustor, and a turbine, fluidly connected to each other;

(b) compressing air using a supplemental compressor driven by a fueled engine;

(c) heating said compressed air by passing both exhaust from the fueled engine and said compressed air through a recuperator; and

(d) increasing power output of said turbine by injecting said heated compressed air into said gas turbine system upstream of said turbine.
