Stainless Steel Models

  • Fluidised Bed
  • Electrothermal Fluidised Bed
  • Rotary Kiln
  • Two-Zone Kiln
  • Electric Arc Furnace
  • Coal-Oxygen Injection Furnace
  • Pyrobal


  • The stainless steel models have traditionally been supplied with Pyrosim to provide some working examples to the new user. These models are now being phased out.

    If you intend using similar process models you should try to configure your own using either an empirical model or an equilibrium model.

    If, however, you chose to run the stainless steel models you would have to run PYRO143.EXE (which is Pyrosim version 1.43) and select the stainless steel (SS) system in the data file selection menu.

    From the Main menu select Models.
