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.
The models are described below.
Gas | CO, CO2, H2, H2O, O2, N2, Ar |
Solids | Cr2O3, FeO, Fe2O3, SiO2, CaO, MgO, Al2O3, Cr, Fe, C, S, P |
Electrothermal Fluidised Bed
Rotary Kiln
Gas | CO, CO2, H2, H2O, N2, Ar, Mg, SiO |
Slag | Cr2O3, FeO, SiO2, CaO, MgO, Al2O3, MgCr2O4, MgAl2O4, FeCr2O4, MnO, TiO2, NiO, CaS, Ca3P2O8. |
Metal | Cr, Cr3C2, Cr7C3, Fe, Fe3C, Fe3Si, Si, SiC, C, Mn, Ni, P, FeS |
Coal-Oxygen Injection Furnace
Pyrobal
The model solves the energy balance based on the temperatures, compositions and mass flow rates of the input and output streams (and the specified process heat losses) and the mass balance (within the constraints of the specified variables, as set by the user).
PYROBAL accounts for the additional energy terms (over or under estimation) resulting from: limestone decomposition; CO2 conversion due to the Boudouard reaction; volatiles present in the coke reductant; and the water gas shift reaction.
Pyrobal has now been superseded by the Empirical Model.
