Abstract

This study selected three types of agglomerated wood charcoal (Agglomerated wood charcoal with charcoal powder, Carbonized wood briquette, Ignition-type of perforated charcoal) that are in circulation in Korea among fuel-type wood products and analyzed the fuel characteristics, harmful substance content, and emissions of air pollutants generated by combustion. The first results showed that charcoal-grilled carbon, which is the raw material of charcoal, produced higher CO than saw-billed carbon. The second result is that the emission standards of air pollutants generated by the combustion of molded wood coal are not up to the emission standards of nitrogen oxides and sulfur oxides in the entire product, compared with the emission criteria of the atmospheric environment preservation method (based on 2019, carbon monoxide: 200 ppm, nitrogen oxides, 150 ppm sulfur oxides: 100 ppm), but the carbon dioxide moulding and carbon dioxide levels were not up. Based on the analysis of combustion gas generated during combustion derived from this study, future research is needed for comparing with the emission standards of pellets, which are wood products for fuel, among the existing biomass burning standards and for reducing carbon monoxide generated during incomplete combustion of agglomerated wood charcoal.

본 연구에서는 연료형 목재제품 중 국내 유통되고 있는 3종의 성형탄(숯가루 성형탄, 톱밥성형탄, 구멍탄착화용 성형탄)을 선정하여 연소특성, 유해물질 함량, 연소 시 발생되는 대기오염물질 배출 특성에 관한 연구를 진행하였다. 연소시 숯가루 성형탄이 톱밥성형탄보다 더 높은 일산화탄소를 발생시켰으며, 성형목탄의 연소 시 발생하는 대기오염물질 배출량을 대기환경보전법 배출허용기준과 비교 시 전체 제품의 질소·황산화물 배출 기준에 미치지 못하였다. 2019년 기준 배출 허용기준으로 일산화탄소 200 ppm, 질소 산화물 150 ppm, 황산화물 100 ppm이며, 이산화탄소 배출 기준은 변경되지 않았다. 본 연구에 의해 생성된 연소가스 분석을 기초 자료로 성형목탄의 연소 시 생성되는 대기오염물질의 배출 계산을 위한 표준에 대한 연구 및 성형목탄의 불완전 연소에 의해 생성되는 일산화탄소 저감에 대한 추가적인 연구가 필요할 것으로 판단된다.
