Why firewood pops and crackles

Firewood popping is dissimilar to firewood crackling.

Firewood popping occurs when called-for wood has a high moisture content.

Gas is created by trapped moisture locked in small pockets within the wood. As the wood burns the wet is heated, and equally the moisture is heated information technology expands and turns into gas.

In one case the gas pressure builds up it will create an free energy outburst with mini explosion. Nosotros hear that energy burst as a pop. When the firewood pops we often see reddish hot firewood embers jumping around and sometimes out of the fire.

Excessive popping is acquired by burning firewood that has not been properly seasoned. Likewise, softwoods with a high sap content tin can pop a lot.

Firewood crackling is due to a couple of processes when burning the wood. The outset is like the above popping. Firewood crackles due to trapped moisture in the wood. The crackling is popping but without as much pressure.

Firewood popping creates sparks

Modest pockets of trapped wet create smaller pops, which we hear as crackling. This is different to popping which is from larger pockets of trapped moisture.

Firewood crackling is also acquired past the release of stresses in the firewood as it is existence burnt. Forest grains concur together forming tight bonds, which is what gives the tree strength. As these grains burn through they become smaller. The smaller grains are no longer able to agree dorsum the stresses from other grains. The wood then moves in unlike directions, which besides creates a crackling audio.

The crackling we hear is the release of those stresses as the wood grains fight against each other.

Why there is moisture inside firewood

As a tree grows it soaks up moisture from ground water which is then stored in the pores of the tree fibers. This moisture substantially waterlogs the woods. The moisture helps to carry the nutrients the tree needs to survive and grow.

Drying or seasoning firewood takes time. Depending on the type of woods and how it is stacked for seasoning information technology tin can take up to 2 years.

Trying to burn unseasoned firewood will consequence your firewood popping excessively. For well seasoned firewood, the moisture content should be below 20%.

Solutions and alternatives to help minimize firewood popping

And then we know that firewood with a loftier moisture content will popular. And popping firewood can be dangerous. It seems obvious that nosotros demand to burn down dry firewood.

A few means to help preclude firewood popping are;

• Stack the firewood properly to ensure the fastest possible seasoning time
• Use kiln stale, or fully seasoned dry firewood
• Test the moisture content of the firewood before called-for
• Use hardwood firewood instead of softwood
• Use the right type of firewood, some forest pops more than others
• Dry pelting soaked or wet firewood
• Employ manufactured burn logs, firewood bricks, or pellets
• Lower the burn rate, or lower temperature fires

Stack the firewood properly to ensure the fastest possible seasoning time

Stacking firewood properly helps the firewood flavour speedily.

Properly stacking firewood likewise stops rain and ground h2o soaking into the woods. Trying to burn down firewood that has recently been wet from rain will crusade all sorts of issues. Which includes popping as well as sizzling. Additionally wet firewood will be hard to calorie-free, and give off less heat.

Purchase kiln dried, or seasoned firewood

Kiln dried firewood is a great option as information technology has a low moisture content and is ready to burn straight abroad. Seasoned firewood is the same. Kiln dried and seasoned firewood is firewood that has a moisture content beneath 20% at the time you lot buy it.

Kiln dried and seasoned firewood are a smashing option if you dont have enough fourth dimension to season firewood your self. Simply be prepared to spend the extra for that convenience. You can expect to pay significantly more than for kiln stale and seasoned firewood.

Test the moisture content of the firewood before burning

Most people cull to flavour firewood themselves. This takes fourth dimension of grade just sometimes it tin can be hard to tell when the firewood is ready and seasoned well enough to burn.

• The signs that firewood is ready to burn are;
• A moisture meter reads below 20% moisture content
• Sparse pieces of firewood a snap when bent, green woods tents to bend without breaking
• The color of properly seasoned firewood will be much darker than unseasoned firewood
• Properly seasoned firewood contains less moisture and volition therefore be lighter, by as much as 25%
• Pieces of seasoned firewood when struck together will give a crisp clanging sound, green wood is more a boring thud

The Environmental Protection Agency has some swell firewood burning tips, including how to test for firewood moisture content.

Utilise hardwood firewood instead of softwood

Typically, hardwood contains less sap and moisture than softwood. Less sap equals less moisture, which equals less firewood popping.

Another benefit of hardwood is that it has more free energy value, therefore hardwood burns longer and hotter than softwood.

That's non to say y'all shouldn't employ softwoods at all. Softwoods are keen for kindling to start a fire. Just trying to keep warm through a long cold winter using softwood as the main called-for firewood is just non efficient. Softwood will burn down through much too fast, unless you lot have lots of wood you might need to replace before the season is through.

Utilise the right blazon of firewood

Its not only about hardwood vs softwood. The incorrect type of hardwood can also pb to more than firewood popping. Hardwood species all accept different moisture and sap content when green.

Some examples of hardwood that have (on boilerplate) a lower (greenish) moisture content are;

• Ash
• Beech
• Cherry
• Elm
• Hackberry
• Maple

These forest types volition usually make for firewood less probable to pop as they contain less moisture when initially harvested.

Some examples of hardwood that have (on average) a higher (green) moisture content are;

• Apple tree
• Birch
• Cottonwood
• Oak
• Sycamore
• Walnut

Notation, the above lists are non definitive. Sub varieties of copse offer different moisture content results. The in a higher place lists should be considered equally typical, and may be useful if you have the option to choose between which type of firewood you can get.

Dry out moisture firewood

If firewood is left out in the pelting it should not exist used until it has had fourth dimension to dry out. If seasoned firewood gets wet from pelting information technology should dry off within a solar day or then once stored in a dry out location.

To dry wet firewood store in a dry location( within is adept) as you would when you are seasoning firewood. Stack logs to stop farther contact with rain, allow sufficient airflow between each log, and raise off the ground to allow drainage.

Bring wood inside and store next to the woods stove to dry out it out before called-for

An piece of cake option is to store wet firewood on a grate next to the wood stove. The rut from the woods stove will dry out rain effected logs rapidly.

Use manufactured fire logs, firewood bricks, or pellets

Fire logs, firewood bricks, and pellets are manufactured products that are ready to employ immediately. Manufactured firewood products are by nature very dry, and have a high energy content.

These manufactured firewood products are fabricated using production processes that densely compress the wood and remove almost of the wet. There will be no moisture pockets in these products and therefore no popping when burning fire logs, burn down bricks or pellets.

Existence and then dumbo, these products are more efficient than most firewood. They will typically provide higher heat and longer burn times than ordinarily seasoned firewood.

Lower the burn rate / temperature of the fire

This fox to burning firewood doesn't necessarily reduce the amount of popping in any given slice of firewood. This is a trick to reduce the frequency of that popping.

The amount of wet trapped in a firewood log is constant, it does not change. Therefore if it has trapped moisture, that moisture will create popping. If firewood has enough moisture for 100 pops then it will pop 100 times, no matter what.

The thought of reducing the intensity of the fire and therefore increasing the burn down time is that those 100 pops occur over a longer catamenia of time, decreasing the popping frequency.

Each firewood log will pop the same amount, but if you fire slower and therefore burn less firewood overall, then in that location is less popping. The case here is a fast burn rate might use 10 firewood logs, each with enough moisture to create 100 pops each. Thats m pops for the fourth dimension the fire is alight.

Burning slower might hateful that you only burn 5 firewood logs before letting the fire extinguish. If those five firewood logs also incorporate plenty moisture for 100 pops each, that'southward 500 pops total. Much less than the in a higher place example of a hot burn down and fast fire.

Is Popping Firewood Dangerous?

Popping firewood can exist unsafe. Popping firewood often throws red hot sparks and embers in all directions.
Hot embers can then offset fires outside of the fire, or burn people directly.

Why should I go on my fireplace fire wood outside?

Firewood exposed to natural air ventilation will proceed to season and dry out. The drier the firewood the less probable it is to popular and crackle when burnt.
