Title (EN) A METHOD FOR OPERATING A GAS TURBINE
(FR) PROCÉDÉ DE FONCTIONNEMENT D'UNE TURBINE À GAZ
Abstract:
(EN) The gas turbine comprises a compressor (10), a combustor (20), and a turbine (30). The method comprises: compressing air with the compressor and feeding compressed air continuously to the combustor, feeding fuel to the combustor, continuously firing the mixture of fuel and gas in the combustor, feeding combustion gases from the combustor to the turbine, and supplying at least a 10 portion of the total amount of fuel that is supplied to the combustor intermittently.
(FR) La présente invention concerne une turbine à gaz, comprenant un compresseur (10), une chambre de combustion (20) et une turbine (30). Le procédé consiste en : la compression d'air par le compresseur et l'alimentation en air comprimé en continu dans la chambre de combustion, l'alimentation en combustible de la chambre de combustion, l'allumage en continu du mélange de combustible et de gaz dans la chambre de combustion, l'acheminement des gaz de combustion de la chambre de combustion à la turbine et la fourniture d'au moins une partie de la quantité totale de combustible qui est introduite dans la chambre de combustion par intermittence.
