Why Does Burning Wood Pop. As the trapped moisture heats up, it will. In all actuality, these popping and cracking sounds are coming from a chemical reaction inside of your fireplace.
Gas is created by trapped moisture locked in small pockets within the wood. Gases expand rapidly when heated. In basic terms, it has something to do with the combustion gases escaping from the wood.
Unlike wood, water doesn’t convert into heat when burned. Some will get stuck in the wood. As the wood burns the moisture is heated, and as the moisture is heated it expands and turns into gas.
As the wood heats up, the warmth penetrates deep into these pockets. In basic terms, it has something to do with the combustion gases escaping from the wood. As they expand, they put tremendous pressure on the walls of the pockets.
Finally, the walls can’t take the pressure anymore and burst. If you place a pot of water on the stove and activate the burner, it will evaporate as steam. When the wood is burned, combustible gasses will be released.
Gases expand rapidly when heated. In all actuality, these popping and cracking sounds are coming from a chemical reaction inside of your fireplace. Trapped moisture can also cause wood to pop and crackle from the creation of steam.
