A system is disclosed that provides for a more efficient combined cycle turbine system by using heated coolant returning from the gas turbine engine (40) to pre-heat fuel (25, 10) before that fuel is injected into the combustor (30). Coolant, such as steam, that is used to cool gas turbine combustors and/or transitions carries high grade heat energy that was removed from the top cycle. By returning the heat energy to the incoming fuel, energy is recovered at a more efficient rate than would result from recovering that heat energy in the bottom cycle.
Système constituant un système de turbine à cycle mixte plus efficace du fait de l'utilisation du fluide de refroidissement réchauffé en provenance de la turbine à gaz (40) pour préchauffer le carburant (25, 10) avant qu'il soit injecté dans la chambre de combustion (30). Le fluide de refroidissement, par exemple de la vapeur, utilisé pour refroidir les chambres de combustion ou les unités de transition de turbine à gaz véhicule une chaleur de haute température extraite du cycle supérieur. En restituant cette chaleur au carburant d'alimentation, on opère une récupération d'énergie plus efficace que ce ne serait le cas si la chaleur était extraite dans le cycle inférieur.
