知识学习|木屑颗粒燃料特性 Characteristics of Wood Pellet Fuel

文章出处:本站 人气:113 发表时间:2017/3/1 9:14:49

      木屑颗粒燃料属于生物质燃料的一种。是通过压缩湿锯末和木屑而制成的,这些颗粒形状大小相近长约1英寸,直径为1/4-5/16英寸。与其它生物质燃料不同,木屑颗粒更容易使用需要较少的存储空间。它们的交付比化石燃料更加安全以及更具优势,因为热量含量高每磅有近7750 Btu(英国热量单位)。其水分含量4-6%左右。这些特性与植物木质素有助于使其保持紧凑的结构,使木屑颗粒成为首选的燃料。
Wood pellet fuel belongs to the category of biomass fuels. It is produced automatically by compressing wet sawdust and green wood chips and forming them into pellets of the same form and size of about 1-1? inches by 1/4-5/16 inches in diameter. As distinct from other biomass fuels, wood pellets are easier to use and need less storage space. They are also less dangerous to deliver than fossil fuels and more advantageous because of the high energy content by weight of almost 7,750 Btu per pound. Their moisture content equals from four to six percent. These properties and plant lignin helps to retain their compact structure and makes wood pellets a first choice fuel.


木屑颗粒等级不是按木材类型划分的。传统的木屑颗粒是根据所产生的灰份含量分类。在此分类下有三个等级:
There are no pellet classifications based on wood type. Traditionally wood pellets are classified according to the amount of the ash produced.

高级Premium

灰分含量<1%
ash content of wood pellets less than one percent

标准Standard

1-2%灰分含量
ash content between one and two percent

工业Industrial

灰分含量3%以上
ash content three percent or more

There are three grades in this classification.
前面两个等级是可以作为商业、工业或住宅用途出售。它们非常适用于各种类型和尺寸、配有自动除灰系统的锅炉。第三个等级的有3%以上的灰分含量的颗粒适合工业应用。
Two first grades may be sold for commercial, industrial or residential use. They are good for boilers of any type and size equipped with automatic ash removal system. Pellets belonging to the third grade with ash content of three percent or greater should be bought for industrial application only.
