    Jan 17, 2017 However, in this kiln coating estimate program a steady state model is sufficient and it is preferred not to cope with dynamics of the kiln while the simulation is performed. This is due to the fact that the run time for the kiln simulation is much lower than the dynamics of the kiln as well as the dynamics of coating variations.
