Abstract :
The paper applies a two-stage modelling concept to a gas-gas heat exchanger located in a tyre production plant. Modelling relies on combination of prior knowledge and recorded data. During the identification procedure the estimates of continuous model parameters are calculated by the least squares method with state variable filters (SVF). The main issues of the modelling procedure are stressed. Based on the process model a simple detector is derived. An excerpt of the results obtained on operating records is given.
