摘要： Disclosed is a method for the chemical water-steam conditioning of a water/steam/condensate medium which is conducted in the water-steam cycle of a particularly fossil fuel-operated, continuous steam generator (1) of a power plant and is fed to an air condenser (12) arranged downstream of a turbine system (8) in the water-steam cycle, said water-steam conditioning encompassing the metering of an alkalizing agent into the water/steam/condensate medium. The aim of the invention is to find, for said method, a solution which prevents erosion corrosion and corrosive nitrate and/or nitrite formation during a combined treatment (OT process) or neutral treatment when air-cooled condensers made of ferritic material are used in the water-steam cycle of a steam generator. Said aim is achieved by in particular additionally metering the alkalizing agent into the water/steam/condensate medium downstream of the continuous steam generator (1), preferably in the zone of at least one low-pressure turbine (1) and/or downstream of a low-pressure turbine (11), before the medium penetrates into the air condenser (12), and by adjusting and carrying out an all volatile treatment (AVT) of the water/steam conditioning process.
