Moisture captured in the wood expands and pops causing sparks to fly which may create a fire hazard beyond the hearth.
that black powder is called carbon
When burned for fuel, wood releases about 3,800 to 4,800 calories per pound.

When burned, the block of wood will decrease in shape and volume due to the release of gases like carbon dioxide and water vapor. The piece of stone, on the other hand, will not be affected by burning and will retain its original shape and volume.
wood We burned wood in the camp fire. The table is made of wood.
All wood can be burned. Wood is largely cellulose, and cellulose is combustible. Sap, tar, or pitch in wood will also burn. Certainly we can treat wood to minimize its combustion potential, but all wood can be burned in a hot enough fire.
Charcoal?
When wood is burned, the carbon in the wood combines with oxygen in the air to form carbon dioxide, leaving behind black carbon residue known as charcoal. This is why the wood turns black when burned.
When bread and wood are burned, the main components, such as water, carbohydrates, and cellulose, are converted into energy, heat, carbon dioxide, and water vapor. Other trace elements and impurities in the materials may also be released as gases or remain as ash.
