Wood Pellets Benefits
At present, wood pellets are very popular in many countries. Maybe some people wonder it. In the following, we, as a top leading pellet mill supplier in China, will help people analyze the reason.
Before analyzing the reason of the popularity of wood pellets, we will introduce what are wood pellets.
Wood pellets are a refined and densified biomass fuel that is formed when wood residues are compressed into a uniform diameter under high pressure. Wood pellets have a uniform shape, size and density and are ideal for automatic combustion heating systems such as pellet stoves and boilers. By pelletizing wood residues from sustainably harvested biomass and quality waste wood, millions of tons of biomass can be put to work for the local economy while at the same time preserving the environment.
After the above introducton, we know that because of their materials, wood pellets should have the same advantages as wood: local, abundant, renewable, and low-cost.
In addition, wood pellets are very low in moisture and ash content, so they burn hot and cleanly. Fuel pellets are limited to 1 percent to 3 percent ash. Regualr firewood has more ash because of the bark. Wood pellets also are small and easy to handle. They are generally available in 40-pound bags, but in some areas they are available in bullk. There is very little dust and no bark. Many wood pellet burning machines have hoppers with feed screws that feed the pellets into the fire when fuel is needed.
Larger furnaces are available that have large storage silos that also automatically feed fuel into the furnace when needed. Both systems require little maintenance because the pellets burn so cleanly. Pellets have a number of “environment-friendly” attritutes. Pellets usually are made from wood-processing byproducts, so they are making a valuable product from a potential waste material. More recently, low-quality trees from forest thinnings and slavage operations have been used. Pellets contain much less water and are denser than firewood, so they are more efficient to transport. Wood and wood pellets are “carbon-neutral” in terms of their contribution to global climate change: all the carbon dioxide that is released when wood is burned was captured from the atmosphere when the wood was grown in the tree. This is an important advantage, especially in some countries in Europe where restriction on carbon emissions are growing.
Wood also is less expensive than most other fuel options. Pellets are more expensive than some other forms of wood fuel, but they usually are cheaper than oil, matural gas or electricity.
In a word, wood pellets are the best choice as fuel.
