Abstract

In an air storage power station heat is withdrawn from the compression process via a heating element (18) and passed into a heat storage device (15). During turbine operation the cold compressed air taken from the air reservoir (1) is first pre-heated with the stored heat in an air heater (21) and then passes via the recuperator (14) to the gas turbine (12',12"). In this way low-temperature corrosion at the exchange surfaces of the recuperator (14) on the flue gas side is avoided, especially during start-up of the gas turbine.
