Abstract
A power plant including a gas turbine, a waste heat steam generator and an intermediate circuit having a first heat exchanger, which is connected to an air inlet of the gas turbine, and a second heat exchanger, which is connected to a condensate circuit, having a condensate preheater in the waste heat steam generator. A first and a second high load valve, and parallel with these a first and a second low load valve for lower volume flows than through the first and second high load valve, are arranged on either side of the second heat exchanger. An associated method for optimizing efficiency and extending the operating range of a power plant.
