Parametric Study of Induction Heating System for Hot-air Generator Application

This study focused on the influenced parameters of the induction heating model for hot-air generator. Instead of ohmic heating, the hot-air generator on the induction heating as the new energy resource was studied. The hot air bulb on induction cooker was applied as a numerical model to achieve the air temperature of 250C with 1,000 watts. As the hot-air generator with induction heating model, the air velocity, bulb geometry, bulb inlet diameter and bulb outlet diameter were conducted to investigate the air temperature and velocity profile. The numerical results showed that the air temperature and air velocity significantly affected by bulb geometry, bulb inlet and bulb outlet diameter. This research shows that induction heating can be applied to a hot air generator with a temperature of more than 250C within 13 minutes at a power of 1,000 watts. Induction heating can also be used as a method for creating hot fluids.
