Abstract:
Rice husk (biomass fuel) samples have been dried in drying oven and a series of drying curve for illustrating moisture migration of rice husk have been obtained. It is first research for rice husk drying, and it can provide reference of fuel processing for different boilers which require rice husk with various water contents. In this paper, we apply Page equation to reflect the drying process and obtain drying characteristic curve, then analyze the drying law. Kinetic analysis of the results of moisture migration test has been done, after which, effective moisture diffusion coefficient, activation energy and drying kinetic equation of rice husk samples are obtained in test temperature range (80-130 ℃). And these results show specific influence law of temperature for effective moisture diffusion coefficient.
Key words:  rice husk  drying characteristic curve  effective moisture diffusion coefficient  activation energy  kinetic analysis
