Wood / firewood
When judging trees as firewood, there are roughly two types: hardwood and conifer.
[Conifer] Burning x: Burning ○ "There is a lot of sap and burning, but there is a lot of smoke and tars, and burning is poor."
Basically, this is said. Of course, even if the same hardwood or coniferous tree has different hardness depending on the type, there are three types of three ways to burn.
Also, the heat of coniferous trees is suitable for warming up, and the heat of hardwoods seems to be painful. (Anything has different wavelength of heat wave?)
Tree Dictionary Take a look
Water content
A tree is a living creature that sucks up water from the ground like a straw and grows up, so the inside of the tree contains a lot of water.
The firewood sold has a low moisture content and burns well because it has been dried for 1 to 2 years, but falling trees and freshly-cut live trees have a high moisture content and are difficult to burn You can also do it. Especially when igniting, you may not be able to catch the fire at all if you do not take proper steps.
Also, even when dry firewood is placed directly on the soil, it absorbs moisture and makes it difficult for the fire to set, so it is possible that the fire will not rise at all if you wake up in the morning and try to set the fire. .. Therefore, rack for placing firewood is also sold.
I often ask you to put it near a bonfire to dry it, but that's enough to wet the surface, even if you put raw wood near the bonfire for 2 days a day. The amount of water in is changed only by a very small amount. It's an effective way to get wet in the rain and absorb water from the ground.
If it gets wet due to rain, it is also effective to scrape off the surface with a knife or cut it with an ax.
It's a digression, but it seems that even firewood with a water content near 0% will not burn easily because it is too dry. Is anything like wood gas going to disappear?
Hardwood
A tree whose leaves are flat and spread. When you look at the whole tree, there are many trees that are thick and have a wide trunk with a branch.
A broad-leaved tree that is generally dense and has poor ignitability, but has good fire retention and is often recommended for bonfires.
When purchasing at campsites, etc., it is often higher than coniferous trees.
Hardwood is inferior to coniferous trees in flames, but it's a big fire and has a high amount of heat, so it's ideal for firewood used for cooking. There are many firewood that lose their shape while burning.
Because there are many hard trees, it is difficult to cut them with a saw or scrape them with a bushcraft.
In addition, unlike softwood, the amount of soot is small, so when you burn a wood stove with an entto structure, hardwood is easier to maintain.
Conifer
A tree whose leaves are thin and sharp like needles. When you look at the whole tree, there are many trees that grow thin and straight up and look like a triangle.
Generally, it is a coniferous tree that has good ignitability because it contains sap, but it has poor fire lasting and is suitable for burning a lot of smoke and tar.
When purchasing at campsites, etc., it is often cheaper than hardwood.
Since coniferous trees contain a lot of oil and woody gas, they burn up with a flame, making them ideal for firewood. I tend to fall apart while maintaining the shape and on the verge of burning out.
It is often said that hardwood is recommended for firewood, but I like conifers when it comes to bonfires because it raises the fire.
It's also light and soft, so it's very easy to process with Bushcraft.
Although it is said that there is a lot of tar and smoke, if it is a solid dry one, the impression is not much different from a hardwood.
bamboo
It is rarely used for bonfires, but I will also explain the nature of bamboo in bonfires.
The image is a tree with high ignition and high firepower and a short life, like a reinforced version of coniferous trees. Basically it is used as a fire.
Bamboo contains highly flammable oil, so if you set it on fire, it will burn immediately like an igniting agent and immediately turn into charcoal, so bamboo enthusiasts call it a booster.
It is important to note that bamboo is hollow and if you put it in a fire as it is, the air inside will expand and explode, so be sure to crack it before heating.
The original name of firecracker is this rupture. I get hurt normally.
Crater
It is a material that is ignited with an igniter, and is read as "Hokuchi".
Immediately it burns out, but with an igniter, it quickly catches fire and has a wide range of combustion.
Tinder is called Tinder in English because I call it Tinder in English.
Basically, it's something you prepare in advance, and you rarely pick it up outside (I think).
The following materials are often used for craters.
- Fatwood
- Dry grass and leaves
- Straw
- Pine cone
- Sarno deer
- Bark such as birch
- newspaper and tissue
- Twine
- feather stick
- steel wool
- vaseline
- Gum tape
- ignition agent
- paracord
It is necessary to create a dedicated feather stick for the feather stick.
Vaseline is applied to the crater to improve the fire lasting rather than using it alone.
The paracord has a dedicated core that can be used for the crater. This guy
There are no other people who make their own tinder soaked with tar or oil.
Survival technique can be used as a crater by collecting lint from socks and sweaters, or by collecting fibers from yarn with a knife.
Burning
The first material to ignite from the crater.
In terms of images, it is difficult to light a fire with a lighter.
It is used to ignite firewood that burns widely and long after receiving a crater that disappears quickly. Many are about the thickness of a finger or less.
The following is the firing that is often used for the crater.
- twig
- finely chopped firewood
- split chopsticks
- pine cones
- dry grass and leaves
- feather stick
Basically, a large amount of craters can also be fired, so there are many similar materials. Something can be called burning.
The reason for breaking the firewood into small pieces is to use it for this burning.
On the net, firewood for burning Right. I'm surprised.
