Disclosed is a gas and steam turbine (1) with a waste steam generator (4) which, seen from the flue gas, is located upstream from the gas turbine. The heated surfaces of the waste steam generator are connected to the steam-water circuit (20) of a steam turbine (21), the gas turbine being submitted to a reliable cooling process under various operating conditions. In order to refrigerate the gas turbine (6) coolant, the inventive system comprises a heat exchanger (74) which is connected, on the secondary side, in the water-steam circuit (76) linked as a locking element to the water-steam circuit (20) of the gas turbine (21).
La présente invention porte sur un système de turbines à gaz et à vapeur (1) avec un producteur de vapeur perdue (4) qui, du point de vue des gaz de combustion, est installé en aval de la turbine à gaz. Les surfaces chauffées du producteur de vapeur perdu sont branchées sur le circuit vapeur-eau (20) d'une turbine à vapeur (21), la turbine à gaz étant soumise à un refroidissement fiable dans différentes conditions de fonctionnement. Pour le refroidissement de l'agent réfrigérant de la turbine à gaz (6), le système en question comprend un échangeur de chaleur (74) qui est branché, côté secondaire, dans le circuit eau-vapeur (76) relié avec fonction de verrouillage au circuit eau-vapeur (20) de la turbine à gaz (21).
