Zusammenfassung

This work proposes a methodology that combines distributed and lumped models tosimulate the current distribution within an indirect heat resistance furnace and, inparticular, to calculate the current to be supplied for achieving a desired power output. The distributed model is a time-harmonic eddy current problem, which is solvednumerically using the finite element method. The lumped model relies on calculatinga reduced impedance associated with an equivalent circuit model. Numerical simulations and plant measurements demonstrate the effectiveness of this approach. Thegood correlation between the results indicates that this approximation is well-suitedto support the design and improve the efficiency of the furnace in a short time
