Residential Usage of Wood Pellets

The development of new energy resources and energy saving are becoming more and more popular as the energy supply intensity. Except of developing all kinds of green energy and saving energy through daily action, we can also use all kinds of wastes materials to produce energy, such as the organic wastes can used to produce methane, and the wood wastes can used to produce wood pellets.

The naturally dead trees and the wood chips and wood shavings which are produced by the wood sawing mills would be a terrible waste if we just burn them on fire or dispose them freely. Inspired by the feed pellet mills, Europeans firstly compressed the wood wastes into uniformed wood pellets as the heating and cooking fuel for their own house. Right now, wood pellet is the rising star among all kinds of new energies, which has been export & import global wide.

Wood Pellet Specification And Manufacture Standard

In 1980s, wood pellets become one of the house heating and cooking fuels, which first happened in the USA and Canada. Soon after that, wood pellets have been widely applied in Austria and other northern European countries. It is a wood pellet blooming period in German in 1999 and 2000. Till 2008, there are 80 thousand families use wood pellets as their house heating fuel and water boiling fuel. And there are over 8 thousand wood pellet combustion equipment have been used only in North Rhine. As the price of oil and gas keep rising, and the environment friendly burning performance of wood pellets, more and more people start to use wood pellets as their house heating fuel.

The raw materials for wood pellet plant are normally natural dry wood wastes, such as wood shavings, wood chips and natural dead wood, there are no chemical additives in the materials. After high pressure compression, the wood materials are formed into uniformed wood pellets with the diameters of 6mm or 8mm and length 2-3 inches.

To ensure the wood pellet quality, many governments have established their own wood pellet standards. The Germany wood pellet standard is DIN plus, Austria uses the wood pellet standard ÖNORM M 1735. These standards are nearly the most strict wood pellet standard in the world. The moisture content of wood pellets must under 10%, and the ash content is no more than 0.5%, the sulphur content must lower than 0.02%. Use these wood pellet standards, the wood pellet plants and distributors must get the licenses to manufacture and sell wood pellets.

Wood Pellets Advantages

There are several advantages of using wood pellets as the substitute of fossil fuel.

Greenhouse gas reduction

Compare to fossil fuels, wood pellet fuel is accordant with environmental protection concepts, there are 35kg carbon dioxide will be released when we use wood pellets to generation 1MWh energy. As we all know, if we use electricity, there are 935kg carbon dioxide will be released, and if we use oil fuel, it will release 375kg carbon dioxide. For wood pellet manufacturers, the energy requirements for wood pellet manufacture is also lower than fossil fuels.

Low transportation hazard

As we all know, the large crude oil carrier oil-spill accidents and oil pipe crack problems happens occasionally. The accident will not only cause the fuel loss, but also cause the underground water pollution. Using wood pellets can strongly avoid these kinds of accidents.

Stable material supply

Wood material is environmental friendly and recyclable, we can get the raw material from local. Take German as an example, the wood materials to produce wood pellets is two thirds of the total flowing forest zone. There are more than 40 wood pellet plants in German, with the fast growing wood pellet demand, the number of wood pellet plant will increase, too.

Price advantages

The price of wood pellet is not as easy to fluctuate as coal, oil and gas. The price of wood pellet is stable so that the customers can have a more reliable spending forecast by themselves.

Wood Pellets Combine With Solar Photovoltaic Cell

Wood pellet combustion equipment can be combined with solar photovoltaic cell. In summer, when the sun is strong, there is no need to start the wood pellet combustion equipment, the solar power which is stored in the storage tank is enough for daily energy requirements. When the solar radiation is not enough, the wood pellet combustion equipment will start and supply the needed energy. There are also a system regulator can help you figure out whether the wood pellet combustion equipment should be start or not.

According to the statistics, using the wood pellet and solar photovoltaic cell combine system can help reduce one third of the energy cost.
