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