Claim 0:
1. A method of heating a fluid stream for a power plant comprises:
diverting a portion of a main flow of flue gas from a power plant at a first pressure (P1);
flowing the diverted flue gas through a heat exchanger;
flowing an auxiliary fluid stream through the heat exchanger;
transferring heat from the diverted flue gas into the auxiliary fluid stream in the heat exchanger to raise a temperature of the auxiliary fluid stream from a first temperature (T3) to a second temperature (T4), while lowering a first temperature of the diverted flue gas (T1) to a second temperature (T2);
returning the diverted flue gas to the main flow of flue gas in the power plant at a second pressure (P2).
