Materials for Biomass Pellets

Biomass pellet is a collective term used to describe those fuel pellets which are made form renewable resources to generate heat and energy. Among them wood pellets are the most common type. Wood pellets are compressed, sawdust-size wood fiber. The cylindrical wood pellets have standard size with diameter 6 and 8mm and length four times the diameter. Wood pellets have driven the growth of the pellet market during the past few years, why is this?


Reasons for the growth of the pellet fuel market
The first reason can be the consistent accelerating of the fossil fuels price and price instability. The second comes form the environmental aspects, people give increased attention on the damage of fossil fuels to the environment. Third reason is that wood pellets can be produced locally and made form various biomass materials. Then the reasons can be the advantages of wood pellets, such as their compact size and portability, high energy density and low moisture content, which make wood pellets become a renewable energy sources.
Why pellets instead of logs?
People may confused about why people using wood pellets to generate heat and energy, why not just burn logs? First, logs come form trees that grow slowly in general, while wood pellets can made form various materials which include straws, grasses, energy crops, etc. Second, pellets can be burnt much more efficiently which means pellets can produce less ash, less smoke and more heat.


 Materials for biomass pellets
* Hemp. Hemp is one of the most promising materials for wood pellets production. Hemp can be grown on land unsuitable for most food crops. Besides, it only takes 3 months for hemp from seed to harvest. Further more hemp pellets have very similar combustion energy to most wood pellets and produce similar ash content to standard grade wood pellets.
* Saw milling residues. Planer shavings and sawdust are another feed stocks for wood pellets production. Saw milling residues are the byproduct of lumber manufacturing process, so using these materials to make wood pellets could largely reduce the cost. Besides, using saw milling residues to make wood pellets requires little or no drying, which could also reduce making procedure.
* Crops straw or logging residues. After harvesting, various kinds of straw can be used to make wood pellets. These materials are often regarded as useless and maybe burnt in the field. Producing these materials into valuable wood pellet could make crop production more profitable.
Biomass pellets market continues to enlarge and have great demand. Biomass pellet production line could help you start this business.
