The invention relates to an electrically heated catalyst (EHC, 10) and a start- up method of a gas turbine engine employing an EHC (10) in the combustor (33). The catalyst (10) is electrically heated to a predetermined temperature prior to start up of the turbine system and is turned off when any one of several conditions are met, e.g. the heat of catalytic reaction is sufficient to maintain the catalyst (10) in its steady state condition. The EHC (10) is made of stacked or spirally wound foils (12, 14).
L'invention concerne un catalyseur chauffé électriquement (EHC, 10) et un procédé de démarrage d'un moteur de turbine à gaz utilisant un EHC (10) dans la chambre de combustion (33). On chauffe le catalyseur (10) pour qu'il atteigne une température prédéterminée avant le démarrage du système de turbine. On éteint le catalyseur lorsque toutes les conditions sont remplies, par exemple la chaleur de la réaction catalytique est suffisante pour maintenir le catalyseur (10) dans son état de fonctionnement stable. Le EHC (10) est composé de bobines superposées ou enroulées en spirale (12, 14).
