Answer 2

The advantage of using charcoal instead of just burning wood is the removal of the water and other components. This allows charcoal to burn to a higher temperature, and give off very little smoke (regular wood gives off a good amount of steam, organic volatiles, and unburnt carbon particles — soot — in its smoke).
