摘　　要：以玉米秸秆为原料,利用环模制粒机,进行颗粒燃料制备试验。通过单因素试验考察原料含水率、粒径和发酵时间对秸秆颗粒燃料密度和成粒率的影响;采用二次回归正交旋转组合试验,建立各因素与秸秆颗粒燃料成粒率间关系的数学模型,分析各试验因素影响成粒率的重要程度。通过优化计算,确定秸秆颗粒燃料成粒率最高时的因素优化参数为:原料含水率20%,发酵时间4h,粒径1.66mm,此时秸秆颗粒燃料成粒率为97.53%。试验验证结果表明,最优参数组合实测值与预测值相一致。Taking corn straw stalk as material,using link mold pellet pelletizer,carried on the pellet fuel manufacture experiment was carried on.Through single factor experiment,the influence of moisture content,material size and fermentation time on particle density and granulation rate were studied.Using Quadratic regression orthogonal rotating combination experiment,established mathematics equation of the factors and the straw pellet fuel granulation rate was established,and important degree of each experimental factor on granulation rate was analyzed.Through the optimized computation,definite optimization parameter of the highest granulation rate was： raw material moisture content 20%,fermentation time 4h,particle size 1.66mm,straw stalk pellet fuel granulation rate was 97.53%.The result of verifying experiment indicated that the optimal parameter combination and the predicted data measured were consistent.
