| 中文摘要: |
| 生物质的流化转化是获取生物质能的重要方法之一，单纯的生物质不易流化，在生物质中加入惰性颗粒（石英砂）形成双组份混合物可实现流化.因此有必要对生物质及其与惰性颗粒的流化特性进行研究.该论文在冷态（室温）的条件下，采用降速法，对稻壳，油菜秸秆以及它们相对应的双组份混合体系的流化特性的进行了研究.结果表明石英砂的最小流化速度的理论值与实测值相符；单一组份的生物质颗粒（稻壳或油菜秸秆颗粒）不能正常流化；在稻壳或油菜秸秆颗粒和石英砂双组份混合体系中，稻壳/油菜秸秆的质量分率小于60%时，稻壳/油菜秸秆与石英砂双组分能很好的流化. |

| Conversion of biomass in fluidization is one of the main methods to obtain biomass energy.Its difficult to fluidize pure biomass in this experiment.But its easy to fluidize for the biomass that inert particles(sand) is added to.It is necessary to study the fluidization characteristics of the biomass and inert particles and their mixture.Velocity-reducing method had been applied to research the fluidization characteristics of rice husk,sand or rape straw,sand and their mixture at atmospheric temperature.From the results,the minimum velocity of fluidization was according with calculation value of sand.Pure rice husk or rape straw could not perform normal fluidization.Mixture of rice husk and sand or rape straw and sand can be normally fluidized when the proportion of biomass was smaller (≤60%). |
