숯가마에서 발생하는 대기오염물질의 배출특성에 관한 현장조사 연구

The commercial charcoal kiln was projected the largest source of biomass burning sector in Korea. Commercial charcoal kiln was operated to emit air pollutants into the air without any air pollution prevention equipment. The object of this field survey was to understand characteristics of air pollutants concentration and emission factors and to provide preliminary data for effective processor from oak charcoal manufacturing process. As result of field survey, TSP, PM 10 and PM 2.5 concentration from charcoal kiln were 400~37,000 mg/m³. These values were over the 100 mg/m³ in TSP, this value was effluent quality standard of Clean Air Conservation Act. The average concentration of CO, SO₂ and TVOC were 2~5%. 0~110 ppm and 820~10,000 ppm respectively. The emission factors were 42.4 g-PM/kg-oak in TSP, 40.3 g-PM/kg-oak in PM 10 , 38.2 g-PM/kg-oak in PM 2.5 , 182.5 g-CO/kg-oak, 1.0 g-NO/kg-oak, SO₂ 0.2 g-SO₂/kg-oak and 104.4 g-TVOC/kg-oak. The part of commercial charcoal kiln had air pollution prevention equipment but it was difficult to work properly. Much wood tar excreted in exhaust emissions from oak charcoal manufacturing process. This wood tar was cause of many troubles sticking in the air pollutant prevention equipment. For handling particulate matters and gaseous air pollutants from oak charcoal manufacturing process in biomass burning, air pollutant prevention equipment design and management needs preprocessor for removal wood tar.
