영문 초록

The interests on the environmental problem associated with energy are growing fast in recent years. Many countries enforce the trade restriction such as Green Round in order to preserve their environment. In order to solve these problems, we should develop the new combustion technique and flame diagnosis method in the combustion field. And, it is necessary to find basic information used for improvement of efficiency and reduction to combustion emission. In order to this purpose, this paper is to investigate the combustion emission characteristics changing excess air ratio(a), catalytic materials(Pt, Pd, Pt/Rh) and volume(0.237m3, 0.34m3) in emission after treatment system of model gas turbine combustor. For this purpose, mean temperature, CO, CO2, O2 HC and NOx concentration were measured by changing excess air ratio, catalytic materials and volume at inlet and outlet of catalyst. Each subject is summarized as following. The reduction effects of Pt catalyst-loaded for HC, CO is more notable in the same volume. It was found that volume change of Pt/Rh catalyst-loaded have not an influence on the reduction effects of HC, CO. The reduction effects of Pt/Rh catalyst-loaded for NOx is more notable without regard to the excess air ratio. In case of Pt, Pd catalyst-loaded, excess air ratio have an influence on the reduction effects of NOx and was more notable a=1.26.
