Beschreibung
Zusammenfassung:The method involves heating the fuel by heat exchange with a lubricant of the gas turbine (2) before injecting the fuel into a combustion chamber (8). The fuel flows through a heat exchanger (6) on the secondary side, and the lubricant flows on the primary side. A portion of fuel and a portion of lubricant are guided over at the heat exchanger for temperature regulation. The lubricant is cooled by heat exchange with a medium other than the fuel. An independent claim is included for a gas turbine plant. Die Erfindung betrifft ein Verfahren zum Vorwärmen eines in einer Gasturbine (2) zu verbrennenden Brennstoffs, bei dem vor dem Eindüsen des Brennstoffs in die Brennkammer (8) der Brennstoff im Wärmetausch mit Schmiermittel der Gasturbine (2) erwärmt wird. Die Erfindung betrifft ferner eine Gasturbinenanlage (1) mit einem Brennstoff-Leitungssystem (5) und einem Schmiermittelkreislauf (3), wobei zumindest ein Leitungsabschnitt (7) des Brennstoff-Leitungssystems (5) sekundärseitig in einen ersten Wärmetauscher (6) geschaltet ist, der primärseitig direkt oder indirekt mit dem Schmiermittelkreislauf (3) verbunden ist.
