  提及生物質顆粒燃料質量權衡指標多數人以為熱值是獨一標注,其實生物質顆粒燃料的耐久性是評價生物質顆粒燃料質量的重要性能指標,普通包括生物質顆粒燃料的抗跌碎性、抗變形性、抗滲水性和抗吸濕性等幾個指標。生物質顆粒燃料的耐久性影響生物質顆粒燃料的包裝、運輸及貯存性能,能夠經過抽樣實驗判別生物質顆粒燃料的耐久性能否滿足包裝、運輸及貯存性能的請求。
  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.
  生物質顆粒燃料在消費和搬運過程,由于碰撞和跌落等動作會形成生物質顆粒燃料破碎,影響生物質顆粒燃料的耐久性,所以請求生物質顆粒燃料具有一定的抵御跌落和撞擊的性能,稱為生物質顆粒燃料的抗跌碎性。
  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質顆粒燃料在搬運過程中接受一定的跌落和翻騰碰撞時抗破碎的才能,反映生物質顆粒燃料在實踐條件下的運輸請求。
  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.
  抗變形性主要反映生物質顆粒燃料在接受外界壓力作用條件下抗決裂的才能,決議生物質顆粒燃料的運用及堆放請求。
  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.
  抗滲水性、抗吸濕性分別反映生物質顆粒燃料的滲水才能和吸收空氣中水分的才能,決議了生物質顆粒燃料儲存性能。
  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)抗滲水性
  1) impermeability
  目前生物質顆粒燃料抗滲水性能的測試辦法和評價指標還沒有統一的規范。龍騰機械工程師采用以下辦法:行將成型燃料樣品置于27℃的水面T25mm處,連續察看成型燃料的形態直至成型燃料完整剝落合成為止,以成型燃料在水中堅持完好形態的時間作為評價成型燃料抗滲水性的技術指標,每個樣品記載5次,取均勻值。
  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
  生物質顆粒燃料的運輸或挪動過程中會因跌落損失一定的重量,成型燃料跌落后殘存的質量百分數(即總質量與損失量的差值除以總質量)反映了產品的抗跌碎才能的大小。成型燃料抗跌碎性的測試龍騰機械是參照煤的抗碎強度測定辦法停止,將長度為60~100mm的燃料棒,從2m高處自在落下到堅硬的地板上,然后將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質量百分數,表示燃料棒的抗跌碎強度。
  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)抗變形性
  3) Deformation resistance
  生物質顆粒燃料堆放時要接受一定的壓為,其接受才能的大小反映生物質顆粒燃料的抗變形性才能的大小。以生物質顆粒燃料樣品在連續加載受力時變形決裂的大壓力表示,它反映生物質顆粒燃料的抗變形性及滿足堆放請求。每種樣品記載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)抗吸濕性
  4) Hygroscopicity
  生物質顆粒燃料的抗吸濕性反響了生物質顆粒燃料吸收空氣中水分的才能。其增重的百分比反響了抗吸濕才能的大小。測試辦法是把成型燃料放在相對濕度為100%的密閉環境中,察看它的質質變化。
  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.
  在準備性實驗中,對具有良好松弛密度的成型燃料,它具有很好的抗變形性和抗吸濕性。把成型燃料堆積2.5米左右的高度時,底部的成型燃料沒有發作變形現象,并且在力學性能實驗機上的實驗發現,它抗變形性的才能很強。
  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.
  關于抗吸濕性,準備實驗的辦法是把成型燃料放在相對濕度為100%的密閉環境中,每天察看丈量一次,一個月后發現含水率增加了,而其它性能沒有發作什么改動,可以滿足包裝、貯存和運輸的請求,因而關于燃料棒的貯存條件沒有什么特殊的請求,因而在本次課題研討中關于成型燃料的耐久性就只作抗跌碎性和抗滲水性實驗。
  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、原料含水率對成型燃料抗跌碎性和抗滲水性的影響
  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
  在前面曾經停止了含水率、成型溫度和粒徑對成型燃料松弛密度的影響的一系列實驗。由于成型燃料在實踐運用中要滿足一定的松弛密度,這樣有利于成型燃料的包裝、貯存、運輸和運用請求,因而在停止抗跌碎性和抗滲水性實驗中,只選取成型燃料松弛密度較優的成型燃料為研討對象的。
  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.
  關于具有良好松弛密度的生物質顆粒燃料,它的抗跌碎性才能都很強,大局部成型燃料的抗跌碎性都大于95%,詳細的如下,芒草的抗跌碎性為95.47%~97.34%;木屑燃料棒抗跌碎性為93.65%~97.15%:稻殼成型燃料抗跌碎性為96.53%~98.17%;稻草成型燃料的抗跌碎性為96.46%~99.52%,這就闡明成型燃料都能滿足在包裝、存儲、運輸和運用過程中的請求,這些無謂的損耗很小。
  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.
  總體上看,生物質顆粒燃料的抗跌碎性才能隨著含水率的增加而降低,但降落趨向不明顯。含水率在5. 5%~10.0%范圍內,抗跌碎性才能變化不大,當含水率大于10. 0%時,抗跌碎性才能降落較為疾速,當成型燃料具有良好的松弛密度時,抗跌碎性才能都能滿足包裝、貯存、運輸和運用的請求。
  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)抗滲水性
  2) impermeability
  抗滲水時間與原料的含水率存在著一定的規律性,當含水率太低時,成型燃料的抗滲水性差,并且隨著含水率的進步抗滲水性才能加強,然后又隨著含水率的進步而降低,直至原料無法緊縮成型。芒草成型燃料的抗滲水合成時間為3~26h;木屑成型燃料的抗滲水合成時間為4~17h;稻殼成型燃料抗滲水時間為6~21h;稻草成型燃料抗滲水時間為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.
  很明顯的看出成型燃料的抗滲水時間與含水率的關系,四種生物質表現出相同的規律性。在可成型含水率范圍內,抗滲水時間隨著含水率的增加而增大,抵達一定水平時抗滲水時間開端減小,直至成型燃料無法成型,在實驗范圍內,四種生物質顆粒燃料抗滲水時間長的含水率區間在7%~9%之間,因而市場上對生物質顆粒燃料請求的含稅率也在這個范圍值內。
  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.
