Abstract
Abstract The gas turbine power station, which is of the type utilizing an air reservoir, and is operated in accordance with the method for reducing the amount of NO x and for raising output, possesses an intermediate condensate-vessel and a main condensate-vessel for receiving the condensate which is produced in the compressor-air coolers. From the main condensate vessel, the condensate is introduced into the combustion chambers of the gas turbine, optionally after passing through a recuperator.
