| 1 | 梯牧草草捆压缩蠕变特性的影响因素分析显示文摘蠕变是决定纤维状生物质压缩的一个重要特性,不同的蠕变特性影响压缩过程的能耗.为分析出最佳原料匹配参数,达到降低压缩能耗的目的,采用Burger模型,分析了在不同含水率和切段处理条件下梯牧草的压缩蠕变特性.非线性回归分析显示,Burger模型适用于梯牧草草捆的压缩蠕变过程;试验结果表明含水率对蠕变特性产生较大影响,切段在一定程度上影响蠕变;通过统计学中的主成分分析,将影响蠕变特性的因子分为弹性因子和粘性因子,这两个因子包含了蠕变特性中86.45%的信息;较高含水率条件下不论是否切段,梯牧草的弹性和粘性均较弱.由此得出,在较高含水率条件下时,梯牧草压缩所需能耗应较低. | 王光辉 王德成 TabilL G Opoku A | 2011 | 江苏大学学报(自然科学版)2011，32，1： | 4 |
| 2 | Pelleting characteristics of selected biomass with and without steam explosion pretreatment显示文摘Processing and densification of agricultural biomass into high density and durable pellets are critical to facilitate handling,storage and transportation.Biomass pelleting experiments were designed to conduct single and pilot scale pelleting of non-treated and steam exploded barley,canola,oat and wheat straw grinds acquired from 6.4,3.2,1.6 and 0.8 mm hammer mill screen sizes at 10%moisture content(wb).Single-pelleting was performed by applying compression pressures of 31.6,63.2,94.7,and 138.9 MPa using a close-fit plunger die assembly(die length 135.3 mm and diameter of(6.30±0.5)mm).During pilot scale pelleting,customization of ground straw material was performed by adding steam exploded biomass in increments of 25%to non-treated ground straw for respective biomass at specific grind size.Ground straw samples were conditioned to 17.5%moisture content and 10%flaxseed oil was added to increase the bulk density and flowability of grinds,which resulted in the production of pellets.The quality of pellets from single pelleting experiments was ascertained by measuring their respective density and durability.In addition,the change in pellet density was measured after a storage period of one month to determine its dimensional stability.It was determined that applied pressure and pre-treatment were significant factors affecting the pellet density.Also,bigger grind sizes and lower applied pressures resulted in higher pellet relaxations(lower pellet densities)during storage of pellets.The pilot scale pellet mill produced pellets from ground non-treated straw at hammer mill screen sizes of 0.8 and 1.6 mm and customized samples having 25%steam exploded straw at 0.8 mm.It was observed that the pellet bulk density and particle density are positively correlated.The density and durability of agricultural straw pellets significantly increased with decrease in hammer mill screen size from 1.6 mm to 0.8 mm.Customization of agricultural straw by adding 25%of steam exploded straw by weight is possible,but it did not improve pellet quality.In addition,durability of pellets was negatively correlated to pellet mill throughput and was positively correlated to specific energy consumption. | Phani Adapa Lope Tabil Greg Schoenau Anthony Opoku | 2010 | International Journal of Agricultural and Biological Engineering2010，3，3： | 4 |
| 3 | Optimized design and experiment on ring mold pelletizer for producing biomass fuel pellets显示文摘The forming process of biomass fuel pellets using a ring mold pelletizer was analyzed,optimized,tested and evaluated in this study.The effects of stress amplitude and the stress ratio on the fatigue failure of the ring mold under 4-,3-,and 2-roller designs were investigated.Depending on the calculation of stress amplitude acting on the ring mold,the 4-roller design was chosen for having the smallest value of stress amplitude in this condition.After determining the main design parameters,a three-dimensional model of the ring mold pelletizer was established based on the Pro/Engineer software,and the model was transferred into ADAMS software through Mechanism/Pro which is a dedicated interface software.The ADAMS software was used to run simulations.In order to obtain the highest efficiency and the lowest power consumption,the optimal result was the 4-roller design.Finally,a prototype of the ring mold pelletizer with four rollers was designed and manufactured for biomass fuel pellet production.Corn stover biomass was used as material for experimental manufacturing of fuel pellets.Test and evaluation showed that the optimized pellet durability was 99.79%with ground corn stover particles passing a screen size of 1.97 mm,moisture content of 21.2%w.b.and a material moisture conditioning time of 3.82 h.Pellets formed in the prototype ring mold pelletizer using corn stover had acceptable durability according to European standards. | Gao Wei Lope G Tabil Zhao Rongfei Liu Dejun | 2016 | International Journal of Agricultural and Biological Engineering2016，9，3： | 3 |
