Definitions

  • the invention relates to a method for treating process gas flowing from a furnace space of a pyrometallurgical furnace into a waste heat boiler that is in fluid communication with the furnace space of the pyrometallurgical furnace at a connecting aperture as defined in the preamble of independent claim 1 .
  • the method may include adjusting the amount of gas that is blown into process gas 8 flowing from the uptake shaft 5 of a suspension smelting furnace 1 a into the waste heat boiler 2 based on a calculated sulfatization need of the process gas 8 .
  • the blowing step of the method comprises preferably, but not necessarily, blowing blowing step gas with the gas blowing means 7 into process gas 8 flowing from the furnace space of the pyrometallurgical furnace 1 ; 1 a ; 1 b ; 1 c into the waste heat boiler 2 in the connecting aperture 6 between the furnace space of the pyrometallurgical furnace 1 ; 1 a ; 1 b ; 1 c and the waste heat boiler 2 .
