Why Does Wood Pop When Burning. The popping noise occurs when air pockets in the wood are released. See answer (1) best answer.
As the wood burns the moisture is heated, and as the moisture is heated it expands and turns into gas. Gas is created by trapped moisture locked in small pockets within the wood. In basic terms, it has something to do with the combustion gases escaping from the wood.
These air pockets fill narrow passages within the wooden log. The popping noise occurs when air pockets in the wood are released. If you place a pot of water on the stove and activate the burner, it will evaporate as steam.
Hence, there will mostly be some moisture in the wood. When the wood is burned, combustible gasses will be released. Once the gas pressure builds up it will create an energy burst with mini explosion.
Moisture content that is trapped within the wood can cause a fire to pop. Unlike wood, water doesn’t convert into heat when burned. In basic terms, it has something to do with the combustion gases escaping from the wood.
The holes created by the insects will give the gasses an escape route. This same principle rings true when burning wet or moist firewood. See answer (1) best answer.
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. Firewood popping occurs when burning wood has a high moisture content.
