Exergy Transfer Analysis of Biomass and Microwave Based on Experimental Heating Process

Exergy transfer and microwave heating performances of wheat straw particles as affected by power (250, 300, 350 W), feeding load (10, 30, 50 g), particle size (0.058, 0.106, 0.270 mm) were investigated detailed in this study. The results show that when the increased from 250 to W, average rate range 23.41–56.18 °C/min with exergy efficiency 1.10–1.89%. When 0.058 mm, decreased 20.59–56.18 0.70–1.89%. 10 g, first then 5.96–56.18 0.07–1.89%. highest was obtained at a 300 30 mm.
