Gas turbine energy supplementing systems and heating systems, and methods of making and using the same
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.
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 using a supplemental compressor driven by a fueled engine;
(c) injecting said pressurized air into a rotor cooling air circuit upstream of a rotor air cooler; and
(d) adding exhaust of the fueled engine to exhaust of the turbine, the fueled engine exhaust bypassing the combustor.
2. The method of claim 1 , wherein said pressurized air is not heated by said fueled engine.
3. The method of claim 1 , wherein injecting said pressurized air from said supplemental compressor into said rotor cooling air circuit increases mass flow through said combustor.
4. The method of claim 1 , wherein injecting said pressurized air upstream of said rotor cooling air circuit, minimizes heat rejected from said rotor cooling air circuit.
5. The method of claim 1 , wherein said pressurized air has a lower temperature than a compressed air in said rotor cooling air circuit.
6. 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;
(c) injecting said pressurized air into a rotor cooling air circuit; and
(d) adding exhaust of the fueled engine to exhaust of the turbine, the fueled engine exhaust bypassing the combustor.
7. The method of claim 6 , wherein the pressurized air is injected upstream of a rotor air cooler.
8. The method of claim 7 , wherein injecting said pressurized air minimizes heat rejected from said rotor cooling air circuit.
9. The method of claim 6 , wherein said pressurized air is not heated by said fueled engine.
10. The method of claim 6 , wherein injecting said pressurized air from said supplemental compressor into said rotor cooling air circuit increases mass flow through said combustor.
11. The method of claim 6 , wherein said pressurized air has a lower temperature than a compressed air in said rotor cooling air circuit.
