Abstract
A system and assemblies for pre-heating fuel in a combined cycle power plant are provided. A fuel supply system includes a water heater assembly configured to heat a flow of water using progressively higher grade heat from a multi-stage heat exchanger arrangement. The fuel supply system also includes a fuel heater that includes a first flow path coupled in flow communication with a fuel flow path wherein the fuel heater includes a second flow path coupled in flow communication with a flow path for the flow of water. The fuel heater is configured to transfer heat from the flow of water to the flow of fuel.
