怎么测出木屑颗粒机中原料的水分?

  无论是制作木屑颗粒还是秸秆颗粒,木屑颗粒机对原料的水份都有一个要求,就是在15%~20%之间,水份过高或者过低都不易成型。所以在初步考察原料的时候一定要确定好原料的水份,那么如何才能准确的测量出物料水份呢?
  Whether making sawdust or straw particles, sawdust granulator has a requirement for the moisture content of raw materials, that is, between 15% and 20%, too high or too low moisture is not easy to form. So in the preliminary investigation of raw materials, we must determine the moisture of raw materials, so how can we accurately measure the moisture of raw materials?
  用水份测试仪,这其实不是一个好方法,仪器不便宜不说,还测得不一定准,物料的水份会随着外力的挤压发生变化。比如说锯末,蓬松的锯末跟稍微挤压一下的测出的水份会差别很大。其实,不用那么麻烦,用“土法子”就测的很准,称上一斤锯末,放到微波炉里,烘干,然后称一下少了多少斤两就能算出物料的水份来了。
  This is not a good way to use a moisture tester. The instrument is not cheap, and the measurement is not necessarily accurate. The moisture of the material will change with the extrusion of external force. For example, sawdust, fluffy sawdust and slightly squeezed water will be very different. In fact, it is not so troublesome to use the "earth method" to measure accurately, weigh a catty of sawdust, put it in the microwave oven, dry it, and then weigh how many catties are missing to calculate the moisture of the material.

  (1)生物质成型燃料是经过高压而形成的块状燃料,其密度远远大于原生物质,其结构与组织特征就决定了挥发分的溢出速度与传热速度都大大降低。点火温度有所升高,点火性能变差,但比型煤的点火性能要好,从点火性能考虑,仍不失生物质点火特性。燃烧开始时挥发分慢慢分解,燃烧处于动力区,随着挥发分燃烧逐渐进入过渡区与扩散区,燃烧速度适中能够使挥发分放出的热量及时传递给受热面,使排烟热损失降低。同时挥发分燃烧所需的氧与外界扩散的氧较好的匹配,挥发分能够燃尽,又不过多的加入空气,炉温逐渐升高,减少了大量的气体不完全燃烧损失与排烟热损失。
  (1) Biomass briquette fuel is a lump fuel formed by high pressure. Its density is much higher than that of the original biomass. Its structure and structure characteristics determine the volatile overflow rate and heat transfer rate are greatly reduced. The ignition temperature increases and the ignition performance becomes worse, but the ignition performance is better than that of briquette. Considering the ignition performance, the ignition performance of biomass is still good. At the beginning of combustion, the volatile matter decomposes slowly, and the combustion is in the power zone. As the volatile matter combustion gradually enters the transition zone and diffusion zone, the moderate combustion speed can make the heat released by volatile matter transfer to the heating surface in time, so as to reduce the heat loss of exhaust smoke. At the same time, the oxygen needed for volatile combustion matches well with the oxygen diffused from outside. The volatile can burn out without too much air, and the furnace temperature increases gradually, which reduces a lot of gas incomplete combustion loss and heat loss of exhaust gas.
  (2)挥发分燃烧后,剩余的焦碳骨架结构紧密,像型煤焦碳骨架一样,运动的气流不能使骨架解体悬浮,使骨架炭能保持层状燃烧,能够形成层状燃烧核心。这时炭的燃烧所需要的氧与静态渗透扩散的氧相当,燃烧稳定持续,炉温较高,从而减少了固体与排烟热损失。在燃烧过程中可以清楚地看到炭的燃烧过程,蓝色火焰包裹着明亮的炭块,燃烧时间明显延长。 生物质成型燃料的诸多优势,加之现在的限煤政策,市场需求量很大,销路不愁,是非常好的投资项目。河南豫晖新能源耕耘多年,拥有丰富的经验,为您提供最专业的支持。
  (2) After volatile combustion, the remaining coke skeleton structure is compact. Like briquette coke skeleton, the moving airflow can not make the skeleton disintegrate and suspend, so that the skeleton char can maintain layered combustion and form a layered combustion core. At this time, the oxygen required for the combustion of carbon is equivalent to that of static pervasive diffusion. The combustion is stable and persistent, and the furnace temperature is higher, thus reducing the heat loss of solid and flue gas. The burning process of carbon can be clearly seen in the burning process. The blue flame wraps bright carbon blocks, and the burning time is obviously prolonged. Many advantages of biomass briquette fuel, coupled with the current coal restriction policy, the market demand is large and the market is not worrying. It is a very good investment project.
