About Firewood (we deliver firewood in Cavan)

stack of firewoodGathered and used for fires, firewood may be any kind of wood. Unlike other kinds of wood fuel like pellets or chips, firewood is often not extensively processed and comes in a form that can easily be recognized as a log or branch. Dry, heat-treated firewood is available, but fresh, untreated wood is also acceptable. Both hardwood and softwood varieties exist.

Burning wood is a sustainable option. But the fuel’s demand may outstrip its regeneration capabilities in a given area. There is potential for local wood supply to improve with the implementation of good forestry practices and the development of gadgets that utilise firewood.

Transporting firewood over long distances has the potential to spread disease and introduce invasive species to new areas.

History of Firewood

Prior to the coal used in the Industrial Revolution, i.e. throughout the vast majority of human history, hydrocarbon fuel was mostly obtained from firewood. Therefore, wood botes, or the right to collect firewood, was an important part of many mediaeval leases due to its high value.

The monarch and the peasant, the scholar and the barbarian, equally need still a few sticks from the forest to warm them and prepare their meal, as Thoreau noted in 19th century America: “amazing what a value is still set upon wood even in this era and this nation.”

Harvesting Firewood

How firewood is gathered varies greatly depending on geography and culture. In some areas, you can only collect firewood from designated spots. In certain regions, gathering firewood is an integral component of the process of preparing land for agriculture, known as “field rotation.” Any number of people may participate in the hobby of collecting. Tools and techniques for gathering firewood vary widely.

Storing Firewood

It’s possible to stack firewood in a number of different ways. These might be as basic as stacked stones or as complex as purpose-built towers. When wood is stored, it is often done so in order to prolong the drying process by preventing the wood from coming into contact with any moisture.

Stacks may range from the simplest, where logs are stacked one on top of another, to the most complex, where logs are stacked in a line the length of which is equal to their breadth. How the ends are built will often determine how high the stack is. The height of a log pile that doesn’t have any constructed ends is based on the log’s length and the length of the pile.

Covering wood to speed up the drying process is a contentious topic. It’s important to balance letting as much wind and light into the stack as possible with preventing the wood from becoming damp on the surface. Water-repellent coverings may be made from almost anything, including big sheets of plywood, metal, tiles, oiled canvas, and even inexpensive plastic. When wood is entirely enclosed, the drying process is halted. It is recommended to use pallets or waste wood to keep the wood off the ground and improve air circulation and so prevent decay.

The stack’s ends may be made in a variety of ways. Crib ends are made by securing logs together in pairs, a technique used in certain regions. The pile can also be finished off with a stake or pole driven into the ground. Another option is to stack a number of logs at the end of the rope and tie a cord to each one; then, wrap the free end of the cord around a log in the centre of the pile.

Under a roof: There is no need to worry about rain, snow, or run-off damaging the wood, but enough ventilation must be given if the wood is kept green to prevent the re-condensation of moisture. How things are stacked is determined by their intended shape and arrangement. The most practical and secure way to store wood is in long, vertical rows, whether the wood is split or in ’rounds’ (flush-cut and unsplit segments of logs). There should be enough airflow through the stack if the wood needs more seasoning.

Firewood should be stacked outside with the bark side facing up. Water can drain away and ice or snow can’t accumulate on the wood. Insects like termites are more likely to set up shop within a house if wood is stored in close proximity to it.

Termites and other pests may be brought into a house if firewood is kept inside for a long length of time.

There are a variety of methods for constructing round stacks. There are some that seem like stacks of wood that have been arranged in a circular pattern. More intricate are styles like the American Holz Hausen.

Holz hausens”, sometimes known simply as “wood houses,” are circular structures used to stack wood in an effort to hasten the drying process while using a comparatively minimal amount of space. The standard holz hausen has a diameter of 10 feet, a height of 10 feet, and can store 6 cords of wood. The parts that make up the walls are placed in a radial pattern, and they’re slanted slightly inward for stability. For better airflow, the inside parts are piled on end to resemble a chimney. The bark side should face up, and the top pieces should be angled slightly outward to deflect rain.

chopped firewoodThermal capacity of Firewood

The rate of combustion and the amount of heat produced by firewood are both affected by its moisture level. Water content causes green wood to weigh 70-100% more than dry wood of the same species. A typical definition of seasoned (dry) wood specifies a moisture level of 20% or less. Because it is more consistent with other sources of information, the lower heating value should be used.

How much energy can be extracted from a given volume of wood varies greatly across different types of trees.

More effort is required to evaporate (boil off) the water in the wood before it can be burned if it has a high moisture content. In terms of heat output, dry wood is superior to green wood of the same species.

Energy Output Measurement of Firewood

See some examples of the energy content of various wood types below:

Energy content for heating (million BTU per cord) Value as a heat source (GJ per m3)

Tamarack 22.3 6.5

Birch 21.3 6.2

Conifer, Red 20.6 6.0

White Fir 16.7 4.9 

 

Typically, bundles or trailer loads of firewood will be sold for a certain price. In spite of the fact that a certain volume phrase may be employed, there may be much variety in what this signifies and what the measure may provide as a fuel. Green, unseasoned wood has a lower energy content (at 65% moisture) than the same volume of wood dried to 20% moisture. The best way to approach firewood measurement, whatever you call it, is as a rough guess.
