Trapped moisture can also cause wood to pop and crackle from the creation of steam. This same principle rings true when burning wet or moist firewood. Gas is created by trapped moisture locked in small pockets within the wood.

Why Does Burning Wood Pop & Crackle? Sciencing
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.
When the wood is burned, combustible gasses will be released.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.Once the gas pressure builds up it will create an energy burst with mini explosion.
Although your piece of wood may look and feel quite dry, it definitely has some moisture locked inside of it.Some will get stuck in the wood. Hence, there will mostly be some moisture in the wood.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.
As the trapped moisture heats up, it will.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.See answer (1) best answer.
Firewood popping occurs when burning wood has a high moisture content.
