The wood material itself is cellulose
Wood is a heterogeneous, hygroscopic, cellular and anisotropic material. Wood is composed of fibers of cellulose (40%–50%) and hemicellulose (15%–25%) held together by lignin (15%–30%).[1]
cellulose is
carbon hydrogen oxygen. Wood also has nitrogen and sulfur in it.
...however, when you burn the wood, very little remains but the carbon sulfur and any heavy metals that may have gotten in it.
