Although no overwhelming evidence exists, organic acids and carbon dioxide have nevertheless been implicated as contributors to corrosion problems within the steam-water circuit. A dedicated group of international scientists, power plant chemists and turbine manufacturers has been commissioned under the auspices of the VGB PowerTech e.V. to examine and document the impact of organic matter and dissolved carbon dioxide on materials of construction in the steam-water circuit of power plant. This VGB Working Group "Organic Matter and Carbon Dioxide in Steam- Water Cycles" has produced an Instruction Sheet for organic matter and dissolved carbon dioxide in plant cycle chemistry of power plant.
