4 Conclusion
In summary, the temperature distribution of the SiC bed surface heated
by four 1 kW magnetrons in a self-designed microwave-assisted pyrolysis
large-scale
reactor was investigated by the infrared thermography and simulation.
The effect of working magnetrons
position on the temperature distribution was examined. The results
showed that the temperature distribution of the bed surface was more
uniform and stable when the magnetrons located at the bottom of the
reactor were used. The strategy of experimental measurement for
determination of the temperature distribution on the bed surface in the
microwave large-scale device would promote the industrial application of
the microwave heating technology.
