A Field Survey on the Characteristics of Air Pollutants Emission from Commercial Charcoal Kiln

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, PM10 and PM2.5 concentration from charcoal kiln were 400 similar to 37,000 mg/m(3). 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 similar to 5%. 0 similar to 110 ppm and 820 similar to 10,000 ppm respectively. The emission factors were 42.4 g-PM/kg-oak in TSP, 40.3 g-PM/kg-oak in PM10, 38.2 g-PM/kg-oak in PM2.5, 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.
