Sulfatation of Fly Ash and Deposits

Basic Principle

The Dublix-SulfGen allows to generate SO3 to be selectively injected to the boiler. This is very effective to improve the performance of waste-to-energy or other power plants with chlorine containing fuels. All relevant Operation and Maintenance Key Performance Indicators are drastically improved by the Sulfatation Generator.

  • Chlorides in ash deposits + SO3 --> sulfated deposits + HCl
  • Sulfur in waste --> SO2 --> slow sulfatation / no effect
  • SulfGen           --> SO3 --> fast sulfatation / drastic effect on deposits
  • Stickiness of fly ash and hardness of deposits drastically reduced.
    Customers say: Deposits are now “Removable with a brush” at outages.
