Many of us agree that wood is one of the best fuels; not in vain 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 In recent years it has been superseded by fossil fuels: oil, diesel, natural gas, butane, propane … However, we must be aware that these are non-renewable energy sources, with which sooner or later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 of the different studies) will be exhausted.
Wood belongs to the renewable sources of energy which are grouped under the name of biomass: firewood, shrubs, pruning remains, forest and agricultural residues, waste from the paper industries, manure … If you want to know everything about wood as fuel, keep reading this Green Ecology article.
Wood and ecology
Wood is also a 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.
In addition, while old trees are cut down, new trees can be planted, with which 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.
What are pellets?
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 diesel heating.
