水稻秸秆冷压成型试验得到的成型燃料能耗较高且质量不佳，为提高水稻秸秆成型燃料质量，本次试验利用水稻秸秆成型设备，在不同成型压力、原料粒径、温度以及含水率等工艺参数条件下对水稻秸秆进行热压成型试验。通过分析成型燃料的物理性能，确定各工艺参数最佳选取范围为：粒径0~2mm、温度70~100℃、成型压力8.89～40MPa、含水率12%～25%。为进一步提高水稻秸秆原料成型燃料的质量，提出通过添加木质素含量较高的木屑原料即形成混合原料，并通过对比试验进行研究。结果表明，混合原料可以有效提高水稻秸秆成型燃料的综合质量。%Rice straw cold press process had been done early and the result showed that the energy consumption of pellets was high and the quality of pellets was bad. In order to increase the quality of pellets, the rice straw hot-press forming experiment was carried out under different technological parameters (compressive forces, particle size, temperature, moisture content) by utilizing special briquetting equipment. By checking pellets’ physical properties (loose density, shatter resistance, compressive forces and water resistance), the confirmed best process parameters were as follows: particle size 0-2mm, temperature 70-100℃, compressive forces 8.89-40MPa, moisture content 12%-25%. In order to increase the quality of rice straw pellets, some wood chips were added to the rice straw materials forming the mixed raw material.By analyzing the results of contrast tests, we found that under low compressive forces, the physical property of 1:1 blended material pellets were better than that of pure rice straw and wood chips pellets, and the results also indicated that adding wood chips into the rice straw material could improve the quality of single rice straw pellets.
