This unit is energy controlled, implying that the unit temperature is set by the conditions (chiefly temperature and flowrate) of the feed streams (and the specified heat losses from the unit).Table B1: Fluidised bed equilibrium specification (for stainless steel) GasĬr 2O 3, FeO, Fe 2O 3, SiO 2, CaO, MgO, Al 2O 3, Cr, Fe, C, S, P The chemical species considered to be present in the two phases are shown in the table below."The assumption of complete mixing is not unreasonable while the assumption of equilibrium between solids and gas is open to question." The assumptions made are that ideal mixing occurs between the solid feed materials and the gas, and that these two phases reach equilibrium.
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.įigure B1: The stainless steel models available
If you intend using similar process models you should try to configure your own using either an empirical model or an equilibrium model. The stainless steel models have traditionally been supplied with Pyrosim to provide some working examples to the new user. Pyrosim Manual, Appendix B A P P E N D I X B
