Abstract: A heat exchange circuit in a gas turbine includes an evaporative cooling medium circuit circulating an exchange medium, and a cooling source containing fuel. The cooling source is coupled with a supply line in a heat exchange relationship with the evaporative cooling medium circuit. The exchange medium is cooled by the fuel in the supply line, and the evaporative cooling medium circuit directs the cooled exchange medium through the evaporative cooler. The fuel is heated by the evaporative cooling medium circuit, and the supply line directs the heated fuel to the one or more combustors of the gas turbine. The cooler turbine inlet air results in increased baseload output.
