Abstract: 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.

Abstract: 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.

Abstract: A gas turbine power plant and a method for operating a gas turbine power plant are provided. The power plant includes a gas turbine installation which may supply a mains supply network with electric power and includes a compressor and an associated first gas turbine. Differing from previous gas turbine installations, the compressor of the gas turbine installation and the first gas turbine of the gas turbine installation are decoupled from each other. A second turbine is provided which drives compressor. As a result, the compressor of the gas turbine installation is operated independently of the first gas turbine. Influences on the mains supply network side, such as generating deficiencies in the main supply network, which act upon the first gas turbine as a result of speed reduction, are also not able to have an impact upon the compressor which is decoupled from the first gas turbine.
