Wood pellet fuel is one of typical biofuel, it is usually made of  waste wood chip, saw dust, crop straw, etc. Considering cost saving and environmental protection, more and more people start to use the wood pellets instead of coal fuel.
 

Uses of wood pellet

uses of wood pellet
  • Domestic energy. Wood pellet is an ideal fuel for residents. Not only because wood pellets have high combustion use ratio, easy to store, but also because it is cost-effective. What is more important is that wood pellets are very safe and clean. Wood pellet can be applied in every aspect of our lives like heating, cooking, washing, and etc.
  • Biomass industrial boilers. As the main fuel of industrial boilers, wood pellet replace coal, heavy oil and natural gas, which can reduce the air pollution. In addition to, wood pellet doesn’t contain sulfur and phosphorus that will reduce corrosion and prolong service life of boilers.
  • Power generation. Wood pellet is also used as the fuel of thermal power generation and biomass gasification power generation.  


Advantages of wood pellet

  • Space-saving. Compared to traditional fuel, wood pellet fuel greatly save the storage space, and easy to transport.
  • Safe. Wood pellet is the natural biomass fuel; it has no chemical substances, which mostly avoid the accident like poisoning and explosion.
  • Sustainable utilization. After burning, the stove ash can be used as high quality organic fertilizer for promoting the growth of new plants. The use of wood pellet enters a virtuous cycle.

 Softwood

Softwood is the gymnosperm, such as the pine, rosewood, and fir. Comparatively speaking, the softwood pellet burns more fully.

In general

There are so many people felt that hardwood pellets produce little smoke and ash, and more friendly than softwood pellets. However, the content of ash depend on the wood pellets’ cleanliness, not the raw material. In addition, the quality of the wood pellet mill has a great influence on the content of ash. Compared to the raw material, the pellet machine’s quality can really decides the pellets’ quality.In brief, no matter the hardwood or softwood, a high quality pellet machine will turn them into high quality wood pellets.  (how to How to distinguish the quality of wood pellet? )
