Why Does Wood Pop When Burning. All trees need to take in water to survive. Some will get stuck in the wood.
All trees need to take in water to survive. The holes created by the insects will give the gasses an escape route. Some will get stuck in the wood.
The holes created by the insects will give the gasses an escape route. Trapped moisture can also cause wood to pop and crackle from the creation of steam. Unlike wood, water doesn’t convert into heat when burned.
As the trapped moisture heats up, it will. In basic terms, it has something to do with the combustion gases escaping from the wood. Firewood popping occurs when burning wood has a high moisture content.
Although your piece of wood may look and feel quite dry, it definitely has some moisture locked inside of it. Hence, there will mostly be some moisture in the wood. These air pockets fill narrow passages within the wooden log.
When the wood is burned, combustible gasses will be released. Gas is created by trapped moisture locked in small pockets within the wood. Moisture content that is trapped within the wood can cause a fire to pop.
As the wood burns the moisture is heated, and as the moisture is heated it expands and turns into gas. All trees need to take in water to survive. This same principle rings true when burning wet or moist firewood.
