Abstract
A combined cycle power plant (CCPP) includes a heat recovery steam generator (HRSG) that includes a first economizer and a condensate supply line. The HRSG receives a flow of exhaust gas from the turbine section. The CCPP further includes a fuel heating system that has a fuel supply line and a high temperature heat exchanger. The fuel supply line is fluidly coupled to the combustion section. The high temperature heat exchanger is disposed in thermal communication on the fuel supply line. A high temperature input line fluidly couples the high temperature heat exchanger to the first economizer of the HRSG such that the high temperature heat exchanger receives water from the first economizer. A recirculation line fluidly coupling the high temperature heat exchanger to the condensate supply. A hydro turbine is disposed on the recirculation line.
