Abstract:

An investigation was made of the feasibility of operating a conventional gas turbine by physically separating the compressor from the expansion turbine, thus creating what has been termed the split-turbine arrangement. In this scheme, the compressor would be driven by conventional engines but located remotely from the expansion turbine. In order to analyze the split-turbine cycle the effects of varying pressure ratios, temperature ratios, and airflows were studied. An evaluation was made of the effects of duct losses in the high-pressure air duct between compressor and turbine. The effect of the separated burner in the remote turbine and the feasibility of utilizing a regenerator were determined. All of these effects were evaluated in terms of the thermal efficiency, specific fuel consumption, and net power loss attributed to the ducting. Modified author abstract
