Abstract:
A combined cycle power plant process comprising the steps ofproviding a topping cycle fluid (â€œTCFâ€ ) having a TCF heat capacity (â€œTCPâ€ ) from a topping cycle engine (â€œTCEâ€ ) to a heat recovery device (â€œHRDâ€ ) having an exhaust section, recovering at least a portion of exhaust heat from the TCE in the HRD, providing a bottoming cycle fluid (â€œBCFâ€ ) having a BCF heat capacity (â€œBCPâ€ ) from the HRD to a bottoming cycle engine (â€œBCEâ€ ), and substantially continuously firing the HRD such that the ratio of the flow of TCF to BCF by mass through the HRD exhaust section is maintained substantially equal to the ratio of BCP to TCP.
