Optimizing the Formula for Rice Husk Pellet Fuel Using Orthogonal Array Testing

Abstract:

Orthogonal array testing was adopted to optimize the formula for the molding of rice husk pellet fuel. An L9(34) array was used; moisture content and ratio proportion of the two additives were set as main influencing factors; the calorific value crush resistance, ash content, density and appearance of rice husk pellets were used as indicators. Visual analysis showed that the optimal formula for the molding of rice husk pellets was: 72% husk, with 15% water, 5% glycerol palmitate and 8% anthracite added. Further tests showed that with these ratios, the calorific value of the obtained pellet fuel17.5MJ/kg, crush resistance98%, density650kg/m3, which meets the standard of European biomass pellet fuel industry.
