Many of us agree that wood is one of the best fuels; It is not for nothing that it is the most natural , the one that humans have traditionally used. In recent years it has been superseded by fossil fuels: oil, diesel, natural gas, butane, propane … However, we must be aware that these are non-renewable energy sources, with which sooner or later (depending on the different studies) will be exhausted. Wood as fuel wood energy wood energy advantages and disadvantages
Wood belongs to the renewable sources of energy that are grouped under the name of biomass : firewood, shrubs, pruning remains, forest and agricultural residues, residues from the paper industries, manure.

Wood and ecology
Wood is also an ecological fuel : for example, when it burns it releases CO2 into the atmosphere, but it is the same CO2 that it absorbed from it during its growth. Wood as fuel
In addition, as old trees are cut down, new trees can be planted, thus we see that wood is a sustainable fuel . In the return to the use of wood, the Scandinavian countries are pioneers, showing special care for their forests.
How to use wood for fuel
A good idea is to reuse the wood, for example as heating fuel . In rural areas it is easy to accumulate a few thousand kilograms of firewood to heat up in winter, but in cities it is impossible. An alternative is the use of pellets . wood energy advantages and disadvantages
They are cylinders of compacted biomass , from forest residues and waste of vegetable origin. They are very small: between 5 and 6 mm in diameter and 2-3 cm in length.
Its compact constitution and small size make it possible to automate the feeding of biomass boilers by means of an endless screw system. This fact and the ease of ignition, through a high temperature system, allow the pellet to be used as a clear alternative to heating diesel .
