Technical and economic comparison of steam-injected versus combined- cycle retrofits on FT-4 engines. Final report
- Burns and Roe, Inc., Oradell, NJ (United States)
The study discusses the findings of a conceptual site-specific investigation of the technical and economic aspects of converting the TPM FT4 simple cycle combustion turbines into either the steam injected gas turbine (SIGT) cycle or the combined cycle (CC). It describes the selection of the best retrofit alternatives through the evaluation and data analysis of a large number of sites and units at two utilities. Conceptual designs are performed on the best retrofit alternatives. Flow diagrams and general arrangement drawings are developed for various configurations utilizing drum type and once-through type multipressure heat recovery steam generators. Auxiliary power consumption and capital cost estimates are presented together with an economic evaluation and comparison of the retrofit alternatives. While the investigation is performed utilizing the FT4 combustion turbines, the steps presented in the report may be used as a guide for investigating the conversion of other gas turbines to either cycle at any utility site.
