In Daejon, Korea, 40 tons/day of waste wood, being 95% of the total waste wood
generated daily, was incinerated for the production of heat energy. However, simple
treatment of incineration makes energy efficiency of resource decrease and
accelerates incinerator deterioration due to its high caloric value. In order
to overcome these problems, alternative treatment should be investigated.
The characteristics of waste wood (13.2% of moisture, 81% of combustibles,
5.8% of Ash and caloric value of 4,000kcal/kg on average) were revealed.
Energy efficiency of waste wood is expected to be higher than other wastes.
In addition, elemental composition of waste wood
sample contains 49.3% carbon, 6.0% hydrogen, 37.1% oxygen, 2.2% nitrogen, 0.3%
sulfur, 0.2% chlorine and 5.1% ash.
Heavy metals such as Cr, As, Cd, Pb, Cu, Ni, Hg,
contained in waste wood, were less than 0.1mg/kg, Zn, F and Cr6+
were 0.16mg/kg, 0.66mg/kg and 1.19mg/kg, respectively.
