Why Does Wood Pop In The Fire. When resin bits catch fire, they explode and throw hot sparks up the chimney and out the front of the fireplace. Unlike wood, water doesn’t convert into heat when burned.
Wood is porous and easily absorbs any moisture it. Trapped moisture can also cause wood to pop and crackle from the creation of steam. As the trapped moisture heats up, it will.
Make your fire on a dry surface. When the wood is burned, combustible gasses will be released. As the trapped moisture heats up, it will.
If you place a pot of water on the stove and activate the burner, it will evaporate as steam. Wood is porous and easily absorbs any moisture it. As the gas escapes, the fire will emit an audible pop or crack.
Woods such as red cedar and poplar are resinous, containing tree saps that are highly flammable. Softwoods such as conifers and pines are more likely to spark due to their high resin content. In basic terms, it has something to do with the combustion gases escaping from the wood.
And, in these moments, the popping and crackling picks up and increases until the moisture in. Moisture that might have escaped without a problem will now be trapped inside this freshly formed seal, causing the wood to pop even more frequently than it would have otherwise. The holes created by the insects will give the gasses an escape route.
When resin bits catch fire, they explode and throw hot sparks up the chimney and out the front of the fireplace. This same principle rings true when burning wet or moist firewood.
