Claims
- 1. A gas turbine driven powerplant, comprising:
- (a) compressor means for producing a downstream flow of air;
- (b) a combustor positioned downstream of the compressor;
- (c) a first turbine positioned downstream of said combustor, said turbine coupled to said compressor by a shaft;
- (d) a reheat combustor positioned downstream of said turbine; and
- (e) a second turbine positioned downstream of said reheat combustor;
- (f) said reheat combustor comprising a region within the path of air flow between said first turbine and said second turbine wherein hydrogen-rich fuel introduced into said region auto-ignites to create reheat combustion;
- (g) wherein said hydrogen-rich fuel flows to said reheat combustor through cooling passages in said first turbine.
- 2. A gas turbine driven powerplant as recited in claim 1, wherein said combustor receives a flow of hydrogen-rich fuel.
- 3. A gas turbine driven powerplant as recited in claim 1, wherein said hydrogen-rich fuel flows through cooling passages in said second turbine.
- 4. A gas turbine driven powerplant as recited in claim 1, further comprising heat exchanger means for producing a mixture of combustible hydrocarbon and steam, said heat exchanger means positioned downstream of said second turbine.
- 5. A gas turbine driven powerplant as recited in claim 4, wherein said mixture of combustible hydrocarbon and steam flows through cooling passages in said second turbine.
- 6. A gas turbine driven powerplant as recited in claim 4, further comprising fuel conversion means for producing said flow of hydrogen-rich fuel from said mixture of combustible hydrocarbon and steam.
- 7. A gas turbine driven powerplant as recited in claim 6, wherein said hydrogen-rich fuel flows to said reheat combustor through cooling passages in said first turbine.
- 8. A gas turbine driven powerplant as recited in claim 4, further comprising fuel conversion means for producing said flow of hydrogen-rich fuel from said mixture of combustible hydrocarbon and steam.
- 9. A gas turbine driven powerplant as recited in claim 8, wherein said hydrogen-rich fuel flows through cooling passages in said second turbine.
- 10. A gas turbine driven powerplant as recited in claim 9, wherein said hydrogen-rich fuel flows through cooling passages in said first turbine.
- 11. A gas turbine driven powerplant as recited in claim 1, further comprising a load connected to the shaft connecting said first turbine to said compressor means.
