Title (EN) METHOD FOR PRODUCING AND RESTORING CERAMIC HEAT INSULATION COATINGS IN GAS TURBINES AND ASSOCIATED GAS TURBINE
(FR) PROCÉDÉ DE FABRICATION ET DE RESTAURATION DE REVÊTEMENTS DE BARRIÈRE THERMIQUE EN CÉRAMIQUE DANS DES TURBINES À GAZ ET TURBINE À GAZ CORRESPONDANTE
(DE) VERFAHREN ZUR HERSTELLUNG UND WIEDERHERSTELLUNG VON KERAMISCHEN WÄRMEDÄMMSCHICHTEN IN GASTURBINEN SOWIE DAZUGEHÖRIGE GASTURBINE
Abstract:
(EN) Through the use of different ceramic heat insulation coatings (7, 13) on turbine blades, it is possible to produce or restore different configurations of gas turbines, which are then optimized for a respective baseload operation application or peak load operation application. Differences in the sprayed-on heat insulation coatings (7, 13) can be generated by means of a different material composition of the powder, for example zirconium oxide, by means of a different number of layers (10), by means of different coating thicknesses and/or by means of different porosities.
(FR) L'utilisation de différents revêtements de barrière thermique (7, 13) en céramique sur les pales de turbines permet de fabriquer ou de restaurer des turbines à gaz présentant des configurations différentes, ces turbines à gaz étant alors optimisées pour un domaine d'utilisation correspondant du fonctionnement en charge de base ou du fonctionnement en charge maximale. Des différences dans les revêtements de barrière thermique (7, 13) appliqués par pulvérisation sont obtenues grâce à différentes compositions de la poudre utilisée, par ex. de l'oxyde de zirconium, à un nombre différent de couches (10), à différentes épaisseurs de revêtement et/ou à différentes porosités.
(DE) Durch die Verwendung verschiedener keramischer Wärmedämmschichten (7, 13) auf Turbinenschaufeln können verschiedene Konfigurationen von Gasturbinen hergestellt oder wiederaufarbeitet werden, die dann optimiert sind für ein jeweiliges Einsatzgebiet von Grundlastbetrieb oder Spitzenlastbetrieb. Unterschiede in den aufgespritzten Wärmedämmschichten (7, 13) lassen sich durch eine unterschiedliche Materialzusammensetzung des Pulvers, z.B. Zirkonoxid, durch eine unterschiedliche Anzahl von Lagen (10), durch unterschiedliche Schichtdicken und/oder durch unterschiedliche Porositäten erzeugen.
