Title (EN) HIGH PRESSURE RATIO TWIN SPOOL INDUSTRIAL GAS TURBINE ENGINE WITH DUAL FLOW HIGH SPOOL COMPRESSOR
(FR) MOTEUR À TURBINE À GAZ INDUSTRIEL À DOUBLE CORPS À RAPPORT DE PRESSION ÉLEVÉ AVEC COMPRESSEUR À CORPS À DOUBLE FLUX ÉLEVÉ
Abstract:
(EN) An industrial gas turbine engine for electrical power production includes a high pressure spool and a low pressure spool in which the low pressure spool can be operated from full power mode to zero power mode when completely shut off, where the low pressure spool is operated at high electrical demand to supply compressed air to the high pressure compressor of the high pressure spool, and where turbine exhaust is used to drive a second electric generator from steam produced in a heat recovery steam generator. The high pressure spool includes a high pressure compressor with a inner compressed air flow path and an outer compressed air flow path in which a higher pressure supplies cooling to a turbine airfoil that is then discharged into a combustor of the engine.
(FR) L'invention concerne un moteur à turbine à gaz industriel pour la production d'énergie électrique comprenant une bobine haute pression et une bobine basse pression, la bobine basse pression pouvant être actionnée d'un mode de pleine puissance à un mode de puissance nulle lorsqu'elle est complètement coupée, la bobine basse pression étant actionnée à une demande électrique élevée pour fournir de l'air comprimé au compresseur haute pression de la bobine haute pression et l'échappement de turbine étant utilisé pour entraîner un second générateur électrique à partir de la vapeur produite dans un générateur de vapeur à récupération de chaleur. La bobine haute pression comprend un compresseur haute pression ayant un trajet d'écoulement d'air comprimé interne et un trajet d'écoulement d'air comprimé externe dans lequel une pression plus élevée fournit un refroidissement à une aube de turbine qui est ensuite déchargé dans une chambre de combustion du moteur.
