Resumo

The subject of IVD-work is the simulation of large state changes, as they are occuring at start-up and shut-down operations as well as eventual malfunctions. For their description non-linear time-variant models are required. The solution of the rising energy-balance-differential-equation system is realized by using the substitute temperature function and the decoupled calculation. These procedures are also employed for-optimalizing calculations. They have been successfully proved for the combined-unit of the Gersteinwerk.
