  提及生物质颗粒燃料质量权衡指标多数人以为热值是独一标注,其实生物质颗粒燃料的耐久性是评价生物质颗粒燃料质量的重要性能指标,普通包括生物质颗粒燃料的抗跌碎性、抗变形性、抗渗水性和抗吸湿性等几个指标。生物质颗粒燃料的耐久性影响生物质颗粒燃料的包装、运输及贮存性能,能够经过抽样实验判别生物质颗粒燃料的耐久性能否满足包装、运输及贮存性能的请求。
  Most people think that calorific value is the only label for biomass pellet fuel quality. In fact, the durability of biomass pellet fuel is an important performance index for evaluating the quality of biomass pellet fuel. Generally, it includes several indicators such as anti-breakage, anti-deformability, anti-seepage and anti-hygroscopicity of biomass pellet fuel. The durability of biomass pellet fuel affects the packaging, transportation and storage performance of biomass pellet fuel. Sampling experiments can be used to determine whether the durability of biomass pellet fuel meets the requirements of packaging, transportation and storage performance.
  生物质颗粒燃料在消费和搬运过程,由于碰撞和跌落等动作会形成生物质颗粒燃料破碎,影响生物质颗粒燃料的耐久性,所以请求生物质颗粒燃料具有一定的抵御跌落和撞击的性能,称为生物质颗粒燃料的抗跌碎性。
  In the process of consumption and transportation of biomass pellet fuel, because the action of collision and drop will cause the breakage of biomass pellet fuel, which will affect the durability of biomass pellet fuel, biomass pellet fuel is requested to have a certain anti-drop and impact performance, which is called the anti-drop fragmentation of biomass pellet fuel.

  抗跌碎性主要反映生物质颗粒燃料在搬运过程中接受一定的跌落和翻腾碰撞时抗破碎的才能,反映生物质颗粒燃料在实践条件下的运输请求。
  Drop crushing resistance mainly reflects the ability of biomass pellet fuel to withstand certain drop and roll collisions in the process of handling, and reflects the transport requirements of biomass pellet fuel under practical conditions.
  抗变形性主要反映生物质颗粒燃料在接受外界压力作用条件下抗决裂的才能,决议生物质颗粒燃料的运用及堆放请求。
  Deformation resistance mainly reflects the ability of biomass pellet fuel to resist cracking under external pressure, and decides the application and stacking request of biomass pellet fuel.
  抗渗水性、抗吸湿性分别反映生物质颗粒燃料的渗水才能和吸收空气中水分的才能,决议了生物质颗粒燃料储存性能。
  The impermeability and hygroscopicity of biomass pellet fuel reflect respectively the ability of water seepage and the ability of absorbing water in air, which determine the storage performance of biomass pellet fuel.
  1)抗渗水性
  1) impermeability
  目前生物质颗粒燃料抗渗水性能的测试办法和评价指标还没有统一的规范。龙腾机械工程师采用以下办法:行将成型燃料样品置于27℃的水面T25mm处,连续察看成型燃料的形态直至成型燃料完整剥落合成为止,以成型燃料在水中坚持完好形态的时间作为评价成型燃料抗渗水性的技术指标,每个样品记载5次,取均匀值。
  At present, there is no uniform criterion for testing and evaluating the anti-seepage performance of biomass pellet fuel. Longteng Mechanical Engineer adopts the following method: Put the sample of the briquette fuel at the water surface of T25mm at 27 C, and continuously observe the shape of the briquette fuel until the briquette fuel is completely peeled off and synthesized. The time when the briquette fuel adheres to the perfect shape in water is taken as the technical index to evaluate the anti-seepage ability of the briquette fuel. Each sample is recorded five times and the uniform value is taken.
  2)抗跌碎性
  2) Fragmentation resistance
  生物质颗粒燃料的运输或挪动过程中会因跌落损失一定的重量,成型燃料跌落后残存的质量百分数(即总质量与损失量的差值除以总质量)反映了产品的抗跌碎才能的大小。成型燃料抗跌碎性的测试龙腾机械是参照煤的抗碎强度测定办法停止,将长度为60~100mm的燃料棒,从2m高处自在落下到坚硬的地板上,然后将落下的燃料棒中大于25mm的燃料棒再次落下,共落下三次,以破碎后大于25mm的燃料棒占原燃料棒的质量百分数,表示燃料棒的抗跌碎强度。
  The weight of biomass pellet fuel will be lost due to falling during transportation or moving. The percentage of residual mass (i.e. the difference between total mass and loss divided by total mass) after falling of briquette fuel reflects the ability of product to resist falling. The test of crushing resistance of briquette fuel is stopped by referring to the crushing strength measurement method of coal. The fuel rod with length of 60-100m m is freely dropped on the hard floor from a height of 2m, and then the fuel rod with diameter greater than 25mm falls down three times. The crushed fuel rod with diameter greater than 25mm accounts for the percentage of the quality of the raw fuel rod, indicating the fuel rod. Drop crushing strength.

  3)抗变形性
  3) Deformation resistance
  生物质颗粒燃料堆放时要接受一定的压为,其接受才能的大小反映生物质颗粒燃料的抗变形性才能的大小。以生物质颗粒燃料样品在连续加载受力时变形决裂的大压力表示,它反映生物质颗粒燃料的抗变形性及满足堆放请求。每种样品记载5次,取大值。
  When biomass pellet fuel is stacked, it must accept a certain pressure, and its acceptance ability reflects the deformation resistance of biomass pellet fuel. The maximum pressure of deformation and fracture of biomass pellet fuel sample under continuous loading is used to indicate the deformation resistance of biomass pellet fuel and to meet the stacking requirements. Each sample was recorded 5 times, and the maximum value was obtained.
  4)抗吸湿性
  4) Hygroscopicity
  生物质颗粒燃料的抗吸湿性反响了生物质颗粒燃料吸收空气中水分的才能。其增重的百分比反响了抗吸湿才能的大小。测试办法是把成型燃料放在相对湿度为100%的密闭环境中,察看它的质质变化。
  The hygroscopicity of biomass pellet fuel reflects the ability of biomass pellet fuel to absorb moisture in air. The percentage of weight gain reflects the ability to resist moisture absorption. The test method is to place the briquette fuel in a closed environment with a relative humidity of 100% and observe its quality change.
  在准备性实验中,对具有良好松弛密度的成型燃料,它具有很好的抗变形性和抗吸湿性。把成型燃料堆积2.5米左右的高度时,底部的成型燃料没有发作变形现象,并且在力学性能实验机上的实验发现,它抗变形性的才能很强。
  In the preparation experiment, it has good deformation resistance and moisture absorption resistance for the moulding fuel with good relaxation density. When the moulding fuel is stacked at a height of about 2.5 meters, there is no deformation at the bottom of the moulding fuel, and the experimental results on the mechanical properties testing machine show that the ability of the moulding fuel to resist deformation is very strong.
  关于抗吸湿性,准备实验的办法是把成型燃料放在相对湿度为100%的密闭环境中,每天察看丈量一次,一个月后发现含水率增加了,而其它性能没有发作什么改动,可以满足包装、贮存和运输的请求,因而关于燃料棒的贮存条件没有什么特殊的请求,因而在本次课题研讨中关于成型燃料的耐久性就只作抗跌碎性和抗渗水性实验。
  Regarding the hygroscopicity, the way to prepare the experiment is to put the briquette fuel in a closed environment with relative humidity of 100%. Every day, it is observed and measured. After one month, it is found that the moisture content has increased, but there are no changes in other properties, which can meet the requirements of packaging, storage and transportation. Therefore, there are no special requests for the storage conditions of fuel rods. Therefore, there is no special request for the storage conditions of fuel rods. The durability of the briquette fuel in the study was only tested for its breakdown resistance and water permeability.
  2、原料含水率对成型燃料抗跌碎性和抗渗水性的影响
  2. Effect of Water Content of Raw Material on Drop Crushing Resistance and Permeability of Molded Fuel
  1)抗跌碎性
  1) Fragmentation resistance
  在前面曾经停止了含水率、成型温度和粒径对成型燃料松弛密度的影响的一系列实验。由于成型燃料在实践运用中要满足一定的松弛密度,这样有利于成型燃料的包装、贮存、运输和运用请求,因而在停止抗跌碎性和抗渗水性实验中,只选取成型燃料松弛密度较优的成型燃料为研讨对象的。
  A series of experiments on the effects of water content, molding temperature and particle size on the relaxation density of formed fuel have been stopped before. Because the briquette fuel must satisfy certain relaxation density in practical application, which is beneficial to the packaging, storage, transportation and operation of briquette fuel, only the briquette fuel with better relaxation density is selected as the research object in the experiment of stopping crushing resistance and impermeability resistance.
  关于具有良好松弛密度的生物质颗粒燃料,它的抗跌碎性才能都很强,大局部成型燃料的抗跌碎性都大于95%,详细的如下,芒草的抗跌碎性为95.47%~97.34%;木屑燃料棒抗跌碎性为93.65%~97.15%:稻壳成型燃料抗跌碎性为96.53%~98.17%;稻草成型燃料的抗跌碎性为96.46%~99.52%,这就阐明成型燃料都能满足在包装、存储、运输和运用过程中的请求,这些无谓的损耗很小。
  As for biomass pellet fuel with good relaxation density, its anti-drop fragmentation ability is very strong. Most of the briquette fuels have anti-drop fragmentation ability greater than 95%. Details are as follows: the anti-drop fragmentation ability of awn grass is 95.47%-97.34%; the anti-drop fragmentation ability of wood fuel rod is 93.65%-97.15%: the anti-drop fragmentation ability of rice husk briquette fuel is 96.53%-98.17%; the anti-drop fragmentation ability of straw briquette fuel is 96.46%-99.17%. 52%, which illustrates that the briquette fuel can meet the requirements in the packaging, storage, transportation and operation process, and these unnecessary losses are very small.
  总体上看,生物质颗粒燃料的抗跌碎性才能随着含水率的增加而降低,但降落趋向不明显。含水率在5. 5%~10.0%范围内,抗跌碎性才能变化不大,当含水率大于10. 0%时,抗跌碎性才能降落较为疾速,当成型燃料具有良好的松弛密度时,抗跌碎性才能都能满足包装、贮存、运输和运用的请求。
  Generally speaking, the breakdown resistance of biomass pellet fuel decreases with the increase of water content, but the landing trend is not obvious. When the moisture content is in the range of 5.5%-10.0%, the crushing resistance can not change much. When the moisture content is more than 10.0%, the crushing resistance can fall more rapidly. When the bulk fuel has good relaxation density, the crushing resistance can meet the requirements of packaging, storage, transportation and operation.
  2)抗渗水性
  2) impermeability
  抗渗水时间与原料的含水率存在着一定的规律性,当含水率太低时,成型燃料的抗渗水性差,并且随着含水率的进步抗渗水性才能加强,然后又随着含水率的进步而降低,直至原料无法紧缩成型。芒草成型燃料的抗渗水合成时间为3~26h;木屑成型燃料的抗渗水合成时间为4~17h;稻壳成型燃料抗渗水时间为6~21h;稻草成型燃料抗渗水时间为5~28h。
  There is a certain regularity between anti-seepage time and water content of raw materials. When water content is too low, the anti-seepage ability of briquette fuel is poor, and with the progress of water content, the anti-seepage ability can be strengthened, and then decreases with the progress of water content until the raw materials can not be compacted. The anti-seepage synthesis time of awn straw briquette fuel is 3-26 h; that of sawdust briquette fuel is 4-17 h; that of rice husk briquette fuel is 6-21 h; and that of straw briquette fuel is 5-28 H.
  很明显的看出成型燃料的抗渗水时间与含水率的关系,四种生物质表现出相同的规律性。在可成型含水率范围内,抗渗水时间随着含水率的增加而增大,抵达一定水平时抗渗水时间开端减小,直至成型燃料无法成型,在实验范围内,四种生物质颗粒燃料抗渗水时间长的含水率区间在7%~9%之间,因而市场上对生物质颗粒燃料请求的含税率也在这个范围值内。
  It is obvious that the relationship between water resistance time of briquette fuel and water content is the same, and the four biomass have the same regularity. Within the range of mouldable water content, the anti-seepage time increases with the increase of water content, and decreases at a certain level until the moulding fuel cannot be moulded. In the experimental range, the water content range of the longest anti-seepage time of four biomass pellet fuels is between 7% and 9%, so the tax rate of the request for biomass pellet fuel in the market is also in this range. Within the value.
