Vacuum distillation furnaces (VDFs) are employed for purification and consolidation of heavy metals from their dendritic forms which are entrained with molten salts. The VDF is an induction heated furnace which is operated at a temperature of 700-1400 °C and at a pressure of 0.01-600 torr. To arrive at the adequate design of such type of furnace, magnetic field and temperature distribution need to be accurately predicted inside the furnace. This paper describes the electromagnetic and thermal modeling of vacuum VDF using COMSOL Multiphysics® to arrive at the suitable values of various controlling parameters like coil voltage, frequency , number of radiation shields, etc.
