The increase in the waste accumulation requires an innovation for use a green technology to burn the waste accumulation rapidly in order to protect the environment while saving the consumption of combustion energy. Hence, this paper shows that a new clean technology can be used for the heating and burning of a material rapidly, saving the consumed electromagnetic energy by presenting a computational modelling for the effect of inserting multiple metallic electrodes on the electric field, generated heat, and temperature distribution inside a material exposed to electromagnetic wave. The modelling was implemented computationally by using the three-dimensional finite element method to simulate electric field, generated heat and temperature distribution in a dielectric material containing three metallic electrodes located in a microwave cavity having surfaces of perfect electric conductors and incident microwave port of mode TE10, supplied with 1500 W electromagnetic power and 2.45 GHz operating frequency. The methodology was based on that the electromagnetic wave creates an elevated electric field inside the material between the ends of metallic electrodes. This electric field assists in generating a thermal energy increasing the material temperature to attain the oxidation temperature rapidly. The results showed that the time required to raise the temperature of a dielectric material by 602 K is minimized locally from 12 seconds to less than 1 second due to the presence of metallic electrodes in the material that exposed to electromagnetic wave. The maximum temperature is increased by 100 K when reducing the gap length between the metallic electrodes from 0.0015 m to 0.0005 m. ©2006-2016 Asian Research Publishing Network (ARPN).
