초록
폐기물은 이차연료나 대체연료로 사용될 수 있다. 본 연구에서는 고형연료(SRF)와 건조 하수슬러지를 연소하여 배출되는 중금속물질을 분석하였다. 석탄, SRF, 건조 하수슬러지의 구리(Cu), 크롬(Cr), 카드뮴(Cd), 니켈(Ni), 아연(Zn), 납(Pb), 비소(As), 수은(Hg) 함량을 조사하였고, 각 물질이 연소가스에서 가스상으로 존재하는 농도를 분석하였다. 실험결과, 가스상으로 배출되는 Cu, Cr, Cd, Ni, Zn, Pb의 양은 매우 적은 것으로 나타났다. 그러나 가스상 수은은 연소 배기가스에서 많은 양이 배출되었다. SRF는 연소 배기가스에서 높은 수은 산화도를 보였고, 건조 하수슬러지는 높은 수준의 수은 배출농도를 보였다.
Abstract
Waste can be utilized as secondary or alternative fuel. Solid recovered fuel (SRF) and dried sewage sludge were combusted to investigate heavy metal emissions from their combusiton in this study. Content of copper (Cu), chromium (Cr), cadmium (Cd), nickel (Ni), zinc (Zn), lead (Pb), arsenic (As) and mercury (Hg) of coal, SRF and dried sewage sludge were determined, respectively. Concentrations of these heavy metals in the combustion flue gas were also determined. As a result, emissions of gas-phase Cu, Cr, Cd, Ni, Zn, Pb and As compounds were found to be little. However, a significant amount of gas-phase Hg was emitted from combustion of coal, SRF and dried sewage sludge. While SRF showed a high mercury oxidation percentage in its combustion flue gas, dried sewage sludge showed a high level of gaseous mercury emission.
