CENTRALE ÉLECTRIQUE MUNIE D'UN SYSTÈME D'ADMISSION D'AIR DE LA TURBINE À GAZ

摘要

The invention relates to a power plant (1) comprising a gas turbine (2), a waste heat steam generator (3) and an intermediate circuit (4) having a first heat exchanger (5), which is connected to an air inlet (6) of the gas turbine (2), and a second heat exchanger (7), which is connected to a condensate circuit (8), comprising a condensate preheater (9) in the waste heat steam generator (3). A first (10) and a second high load valve (11), and parallel with these a first (12) and a second low load valve (13) for lower volume flows than through the first (10) and second high load valve (11), are arranged on either side of the second heat exchanger (7). The invention further relates to an associated method for optimizing efficiency and extending the operating range of a power plant (1).
