The Simulation and Optimization of High Power Rectangular Microwave Reactor Loaded with Cylindrical Loads

The high power rectangular microwave reactor with cylindrical loads is modeled and simulated by using the high frequency electromagnetic simulation software HFSS 13. From the simulation, the influence to heating efficiency by feed＂ angels and distance, loads＂ materials, size, and location is computed. By analyzing the relation between design parameters and power reflection, the general results for optimizing rectangular microwave reactor with cylindrical loads are obtained in this paper. As a validation, the microwave reactors with optimal parameters are modeled and simulated again. Computing results showed that the power absorption efficiency can reach up to 98. 5% and 95. 3% when the loads were fly ash and glass respectively.
