Abstract:
A combined cycle power plant process comprising:providing a topping cycle fluid (â€œTCFâ€ ) from a topping cycle engine (â€œTCEâ€ ) to a heat recovery device (â€œHRDâ€ ); recovering exhaust hear from the TCF in the HRD; substantially continuously supplemental firing the HRD; providing a bottoming cycle fluid (â€œBCFâ€ ) from the HRD to a bottoming cycle engine (â€œBCEâ€ ); and modulating the rate of BCF flow through at least a portion of the HRD such that an exhaust temperature of the HRD is maintained at a predetermined temperature range, thereby controlling heat recovery from the TCF in the HRD.
