초록

In this study GC and PAS were used to calculate N2O concentration of exhaust gas from Wood Chip combustion system. Fuel supplied to the incinerator was collected and analyzed and then the analysis result was used to calculate N2O emissions. Tier 3 and Tier 4 Method were used to calculate the N2O emissions. Plant's Specific emission factor of N2O by Tier 3 Method was 0.35 kg/TJ, while default emission factor of Wood․Wood Waste proposed by 2006 IPCC G/L was 4 kg/TJ. So the N2O emission factor of this study was 3.65 kg/TJ lower compared to the IPCC G/L. The total emissions calculated by Plant's specific emission factor was 4.22 kg during the measuring period, but by Tier 4 Method it was 7.88 kg. This difference in emissions was caused by the difference of continuous measuring and intermittent sampling. It would be necessary to apply continuous measuring to calculate emissions of Non-CO2 gas whose the density distribution is relatively high. However currently, according to the target management guideline of greenhouse gas and energy, the continuous measuring method to calculate greenhouse gas emission is applied only to CO2. Therefore for reliable greenhouse gas emission calculation it would be necessary to apply continuous measuring to calculate Non-CO2 gas emission.
