Title (EN) COMBINED CYCLE POWER PLANT
(FR) CENTRALE ÉLECTRIQUE À CYCLES COMBINÉS
Abstract:
(EN) The present invention relates to a combined cycle power plant according to claim 1, comprising an Rankine cycle (10) with a turbine (11), an exhaust gas heat exchanger (12), a pump (13), a condenser (15) and a first generator (G1) driven by the turbine (11); a multi shaft gas turbine cycle (20) with at least two compressor stages (21, 22, 23), a combustor (25), at least one turbine stage (24, 24 ', 24'', 24''') and a second generator (G2) driven by the at least one turbine stage (24, 24 ', 24'', 24'''); wherein in a compressing air path between two compressor stages (21, 22, 23) an intercooler (27, 28) is arranged such that a temperature of the compressed air for the combustor (25) is decreased. The cold side path from the intercooler (27, 28) is connected in parallel to the exhaust gas exchanger (12) of the Rankine cycle (10), such that the waste heat from the intercooler (27, 28) is feeding the Rankine cycle in addition to the exhaust gas heat from the exhaust gas heat exchanger (12).
(FR) La présente invention concerne une centrale électrique à cycles combinés selon la revendication 1, comprenant un cycle de Rankine (10) avec une turbine (11), un échangeur de chaleur de gaz d'échappement (12), une pompe (13), un condenseur (15) et un premier générateur (G1) entraîné par la turbine (11); un cycle de turbine à gaz à arbres multiples (20) avec au moins deux étages de compresseur (21, 22, 23), une chambre de combustion (25), au moins un étage de turbine (24, 24 ', 24'', 24''') et un second générateur (G2) entraîné par l'au moins un étage de turbine (24, 24 ', 24'', 24'''); dans un trajet d'air de compression entre deux étages de compresseur (21, 22, 23), un refroidisseur intermédiaire (27, 28) étant disposé, de sorte qu'une température de l'air comprimé pour la chambre de combustion (25) soit diminuée. Le trajet côté froid du refroidisseur intermédiaire (27, 28) est relié en parallèle à l'échangeur de chaleur de gaz d'échappement (12) du cycle de Rankine (10), de sorte que la chaleur résiduelle du refroidisseur intermédiaire (27, 28) alimente le cycle de Rankine en plus de la chaleur des gaz d'échappement provenant de l'échangeur de chaleur de gaz d'échappement (12).
