The experimental results for the microwave heating of wood were compared with predictions from mathematical model. The wood sample with a dry basis density of 721kg/m3, moisture content of 12.5% and initial temperature of 25 ◦C are used for the present analysis. Since the average moisture content of wood sample is very low and the overall heating time is fast, the moisture content was treated to be constant throughout the numerical calculation of microwave heating process. In the microwave industries, only a few frequencies are available. Currently, two frequencies, 2.45 and 5GHz are utilized for testing the model.
