Why Does Burning Wood Pop. Once the fire burns the wood. As the wood burns the moisture is heated, and as the moisture is heated it expands and turns into gas.
As they expand, they put tremendous pressure on the walls of the pockets. When the wood is burned, combustible gasses will be released. See answer (1) best answer.
Once the gas pressure builds up it will create an energy burst with mini explosion. When the wood is burned, combustible gasses will be released. See answer (1) best answer.
In fact, as the firewood is burning and combustion is being released into the air, the burnt wood is converted into heat and waste gasses. This same principle rings true when burning wet or moist firewood. As the wood burns the moisture is heated, and as the moisture is heated it expands and turns into gas.
At that time, the “popping. As they expand, they put tremendous pressure on the walls of the pockets. The sap/pitch liquifies, then vaporizes as the temperature increases.
As the gas escapes, the fire will emit an audible pop or crack. Trapped moisture can also cause wood to pop and crackle from the creation of steam. Firewood popping occurs when burning wood has a high moisture content.
In basic terms, it has something to do with the combustion gases escaping from the wood. Finally, the walls can’t take the pressure anymore and burst. Some will get stuck in the wood.
