Dissolved salts precipitate as limescale on the surface of walls under the combined effect of a rise in temperature and their concentration in the boiler. Steam cycles' top-up water will therefore always be more or less demineralised, according to the boiler's service pressure.  The dissolved gases, oxygen and carbon dioxide, which are the main factors responsible for corrosion, will be eliminated more by thermal degassing. This treatment will be completed by chemical circuit treatment to:
  • Eliminate the residual oxygen
  • Sequester and disperse the mineral mud
  • Make the thermal exchange walls passive to control corrosion
  • Neutralise the carbon acidity of the condensation returns
