A purging and/or sealing apparatus for conveying a purging and/or sealing fluid to at least one burner of a gas turbine plant. The purging and/or sealing apparatus has a pressure accumulator and a heating device, wherein the pressure accumulator is connected to the at least one burner via a first fluid line, with the heating device connected therebetween. A gas turbine plant and a method for purging and/or sealing has at least one burner and a purging and/or sealing apparatus.

A cooling device for use in a power plant, having at least two controllable fans, which are designed to produce an air flow having a specified flow direction during operation, at least two closing flaps, which close respective flow cross-sections, and a heat exchanger, which thermally interacts with the at least two air flows for heat exchange as a secondary medium, wherein the closing flaps are not operated by a mechanical adjusting device but rather are each to be opened merely by one of the two air flows as a result of the dynamic pressure when a minimum flow rate is reached. Furthermore at least two holding devices are provided, which hold the closing flaps in an open position when the closing flaps are opened.
