Title
(EN) GAS TURBINE SYSTEM
(FR) SYSTÈME DE TURBINE À GAZ
(JA) ガスタービンシステム
Abstract
(EN)
A gas turbine system (S) comprises: a gas turbine engine body (GT) that has a compressor (1) for compressing air, a combustor (3) for mixing fuel into the air that has been compressed at the compressor (1) and causing same to combust, and a turbine (5) that is driven by combustion gas generated at the combustor (3); and a spray nozzle (31) that is provided to an air intake passage (7) of the compressor (1) and sprays water into air that is taken into the compressor (1). The gas turbine system, wherein an extraction port (37) for extracting air from a more upstream stage than an outlet of the compressor (1) is provided to a compressed air supply system (33) for providing compressed air (CA) for spraying to the spray nozzle (31).
(FR)
Un système de turbine à gaz (S) comprend : un corps de moteur à turbine à gaz (GT) qui présente un compresseur (1) pour comprimer de l'air, une chambre de combustion (3) pour mélanger le carburant dans l'air qui a été comprimé au niveau du compresseur (1) et l'amener à brûler, et une turbine (5) qui est entraînée par le gaz de combustion généré au niveau de la chambre de combustion (3) ; et une buse de pulvérisation (31) qui est disposée sur un passage d'admission d'air (7) du compresseur (1) et pulvérise de l'eau dans de l'air qui est aspiré dans le compresseur (1). Le système de turbine à gaz, dans lequel un orifice d'extraction (37) pour extraire de l'air d'un étage plus en amont qu'un orifice de sortie du compresseur (1), est monté dans un système d'alimentation en air comprimé (33) pour fournir de l'air comprimé (CA), pour pulvérisation, à la buse de pulvérisation (31).
