국내 무연탄 화력발전소의 온실가스 배출계수 개발

Although anthracite power plant acts as the important source of greenhouse gas emissions, relatively little is known about its emission potentials. Especially, because the emissions of Non-CO₂ greenhouse gas CH₄ and N₂O are strongly dependent on fuel type and technology available, it is desirable to obtain the information concerning their emission pattens. In this study, the anthracite power plants in Korea were investigated and the emission gases were analyzed using GC/FID and GC/ECD to develop Non-CO₂ emission factors. The anthracite samples were also analyzed to quantity the amount of carbon and hydrogen using an element analyzer, while calorie was measured by an automatic calorie analyzer. The emission factor of CH₄ and N₂O computed through the gas analysis corresponded to 0.73 and 1.98 ㎏/TJ, respectively. Compared with IPCC values, the CH₄ emission factor in this study was about 25% lower, while that of N₂O was higher by about 40%. More research is needed to extend our database for emission factors of various energy-consuming facilities in order to stand on a higher position.
