Advantages of the method

  • cheap and readily available CaCO3sorbent
  • high desulphurisation efficiency exceeding 95 %
  • lower operating costs in comparison with desulphurisation using a fluid absorber
  • low Ca/S stoichiometric ratio
  • possibility of using the desulphurisation product –gypsum by-product
  • generally advantageous application in large boilers
  • according to experiences from the installation at the Planá nad Lužnicí heating plant, it is also advantageous in smaller boilers at a favourable acquisition price
