Abstract:
1. A gas-turbine plant of a power plant, comprising: a compressor, a combustion chamber, a gas turbine and a cooling air-cooler, the cooling-air cooler is configured and arranged to receive a flow of compressed cooling air from the compressor, to cool down the flow of compressed cooling air and to forward the flow of compressed cooled cooling air to thermally loaded parts of the gas turbine and/or the combustion chamber, the cooling air-cooler comprising: a pressure vessel extending along a longitudinal axis from a first end to a second end; a cooling-air inlet at said first end of said pressure vessel and a cooling-air outlet at said second end of said pressure vessel, said pressure vessel being configured and arranged to guide a flow of cooling air from said cooling-air inlet along said axis through said cooling-air outlet, such that cooling air can enter said pressure vessel through said cooling-air inlet, flow through said pressure vessel along said axis as a cooling-air flow and exit said pressure vessel through said cooling-air outlet; within said pressure vessel means for spraying water into the cooling-air flow that flows through said pressure vessel from said cooling-air inlet to said cooling-air outlet, whereby said water-spraying means comprise a plurality of nozzles oriented in parallel to said longitudinal axis such that water is sprayed from said nozzles in the direction of said cooling-air flow; within said pressure vessel heat exchanging means which are arranged in said cooling-air flow; and within said pressure vessel a water separator arranged in said cooling-air flow between said water-spraying means and said cooling-air outlet.
