Metal industries still use furnace that have low efficiency and are based on thermal heating produced by combustion process. To have better cost production and low gas emission, induction heating is a way to be explored. This paper presents an industrial multiphase induction heating process focusing on the inductor's current control. A model of the electrical power part is described linking the power sources, the inverter currents and the power density produced to heat the metal piece. Due to the structure of the global power system, couplings between currents should be well managed to control the temperature. A state space representation is used not only to control in closed loop the dynamics of both currents but also a specified eigenvector placement is forced to get uncoupling and robust behavior of the global system. The results obtained in simulation show good performances and fulfill the industrial constraints.
Computational fluid dynamics is applied to a comparative study of a counter-current reactor and a confined jet reactor for continuous hydrothermal flow synthesis of nanomaterials under supercritical water conditions. ...
