Title
(EN) METHOD FOR REMOVAL OF ENTRAINED GAS IN A COMBINED CYCLE POWER GENERATION SYSTEM
(FR) PROCÉDÉ POUR L'ÉLIMINATION DU GAZ ENTRAÎNÉ DANS UN SYSTÈME DE GÉNÉRATION D'ÉNERGIE À CYCLE COMBINÉ
Abstract
(EN)
A combined cycle power generation system (10) includes a steam turbine (14, 16, 18), a combustion system (12) including a compressor (24), a combustion chamber (26), a gas turbine (28), and a HRSG (20) to generate steam with energy from the combustion turbine. A flow line (60, 70) passes superheated steam into the combustion chamber. In an associated method a first source of power is provided via a combustion process having a variable reaction temperature in a first turbine. A second source of power is provided via a second turbine. Components of the system are placed in a mode of increasing power output with steam generated from the HRSG, during which a portion of the steam is provided into a combustion chamber associated with operation of the second turbine
(FR)
Le système porte sur un système de génération d'énergie à cycle combiné (10), qui comprend une turbine à vapeur (14, 16, 18), un système de combustion (12) comprenant un compresseur (24), une chambre de combustion (26), une turbine à gaz (28) et un générateur de vapeur à récupération de chaleur (20) destiné à produire de la vapeur à l'aide de l'énergie issue à la turbine à combustion. Une canalisation d'écoulement (60,70) fait passer la vapeur surchauffée dans la chambre de combustion. Dans un procédé correspondant, une première source d'énergie est réalisée à l'aide d'un processus de combustion ayant une température de réaction variable dans une première turbine. Une seconde source d'énergie est réalisée à l'aide d'une seconde turbine. Des composants du système sont mis dans un mode de sortie de puissance augmentée avec la vapeur générée par le générateur de vapeur à récupération de chaleur, pendant lequel une partie de la vapeur est envoyée dans une chambre de combustion associée au fonctionnement de la seconde turbine.
