The term firewood , derived from the Latin ligna , allows us to name the part of the bushes, bushes and trees that is used as fuel . Firewood, therefore, is obtained from plant species and is used to light a fire .
Generally used for cooking or heating , firewood is biomass : that is, an organic matter that functions as a source of energy . This is the wood that is used in homes, kitchens, stoves, grills, etc.
Pine , oak , eucalyptus , beech and holm oak are some of the species that are exploited to obtain firewood. When wood is used for cooking, the choice of the type of firewood is crucial since it provides specific flavors and aromas to the preparations.
It should be noted that, when burned, firewood generates byproducts such as soot and tar . In addition, combustion forms water vapor and carbon dioxide and leaves a solid waste known as ash .
When lighting a bonfire or campfire in an open space, it is common for people to use firewood. It is very important to keep in mind that fire is difficult to control outdoors and can therefore cause a fire . That is why you should only light fires in places permitted by the authorities.
The individual dedicated to cutting, collecting and marketing firewood is called a lumberjack . It is usually a person who works in the forest and is responsible for cutting the wood with a saw, ax or other tool, then transporting the logs to a sawmill or store.
In addition to cooking and heating, firewood is used for an "emotional" purpose since the sensations that come with sitting in front of a fireplace in cold weather are very particular. This scene, which for many is typical of a movie, is everyday in the coldest parts of the world, or in those where winter is very harsh.
The difference between a wood-burning fireplace and an electric or gas stove is as great as that between a wood-burning stove and a glass-ceramic stove: the sensation of being so close to the energy source , of seeing it physically, and the results it produces. coming into contact with our body or with food is something that many people regret having lost due to the imposition of modern technology.
As mentioned above, firewood can be obtained from different species of trees, and in this way the types of firewood presented below arise, each one specially designed for a different situation:
* wood briquettes : these are logs that are made from sawdust and shavings. They are ideal for lighting and keeping the fire alive. For better performance, it is recommended to use them in fireplaces with a door or in closed stoves . They are usually sold in packages of more than one unit;
* Holm oak wood : it is one of the most popular woods for ovens and open fireplaces. Among its advantages are that it burns in a short time and lasts longer than other types of firewood. Given its high level of humidity, it is important to dry it well before using it;
* olive wood : its most common use is for space heating because, like holm oak, it produces a high degree of heat and has a good duration;
* ash wood : this type of firewood stands out for the ease of drying it, although this depends on the characteristics of its storage. On the other hand, if it is stored in very humid corners, it is very likely to rot.
