熱交換器のある場合の触媒フラットバーナの基礎特性

The characteristics of a plate burner and a heat exchanger are experimentally investigated in this paper. The present burner consists of a stack of ceramic filaments catalyzed with Pd, which is featured by low concentrations of NO_x and CO. Furthermore, the burner surface emits light and thermal radiation in a high activity region of catalyst. Therefore, the thermal efficiency, that is, heat input to the heat exchanger with regard to combustion load, is expected to increase. In this study the combustion characteristics of this burner and the efficiency of the heat exchanger have been examined to see the efficiency of the system. Two major results were obtained; one is that the thermal efficiency has been improved by about 5%, and the other is that unburned combustion gas after the heat exchanger was reduced because combustion starts on the burner surface. Thus it is confirmed that the catalytic burner is useful for energy saving and downsizing of a combustor.
