, (PressExposure) April 27, 2009 -- http://woodpelletsguide.com : With the pursuit to find a reliable source of energy other than non renewable energy such as fossil fuels, lots of studies and researches has been done through the years. Biofuels made from biomass (organic materials) have been proven to be an effective substitute. These biofuels are derived from biodegradable materials such as manures, plants, etc. Now, let us focus more on another effective organic material, the wood pellets.
In general, the very fine wood particles (sawdust) when compacted turn into wood pellets. These wood pellets are considered to be a form of wood fuel. Wood fuel, in its simplest explanation, is a fuel generated from wood. Wood pellets are normally the byproducts of sawing logs or woods by method of sawmilling. However, this can also be produced by any activities that involve transforming and cutting of woods.
Wood pellets are basically solid and consistently hard. With the pelletsâ very low moisture content (humidity of 6 â 10%), they contain higher energy component that is likely comparable to high caliber coal. This would only means that their low humidity content saves a lot of energy that is needed to burn the amount of moist. These characteristics â a diameter of about 6 â 8mm, usually 2cm long, lower humidity and high density â allows the wood pellets to be automatically used in clean â burn heating appliances. Moreover, these attributes make the wood pellets highly effective as a burnable material.
In addition, since wood pellets are considered to be a biomass, then they should be environmental friendly. They release less emissions and ashes that could be detrimental to the surroundings. As mentioned, these pellets are compacted, thus they do not need a lot of space unlike any other type of wood fuel. This would also make it easier to ship even in long distance.
Not frequently used to manufacture pellets are similar organic materials such as straw, corn, etc. As a renewable material, wood pellets give the benefit of continuous energy supply. Moreover, woods and logs are not basically cut down to produce wood pellet but they are merely the byproduct of any wood processing activities. Also, pellets are actually waste materials, therefore utilizing them as an energy source would mean lessening the problem on waste disposal.
With the current situation, where the cost of fossil fuels is expected to continually rise, installation for more capable pellet heating systems resulted. From the year 1999, there have been numerous pellet stove models, heating furnaces and other form of heating machines that are widely distributed in the markets.
These stoves specifically designed for wood pellets are advantageous over other types of home heating systems. The usual wood stoves need more constant maintenance compared to wood pellet stoves. They are easy to operate and even more convenient than using traditional stoves. Though physically, they may look like the usual traditional stoves, however, they have microprocessor controls that ensure a clean and efficient fire.
As of 2005, the demand for wood pellets as a wood fuel has significantly increased due to costly fuels in different parts of the world.
