다국어 초록 (Multilingual Abstract)

Currently, most of the recuperator using stainless steel, however, this severely limits due to high-temperature corrosion / oxidation of metallic materials and chemical erosion by impurities of fuel. Ceramics, an alternative to metals, offer the potential to high temperature (over 1300℃) and corrosive environments. However, a ceramic recuperator analysis still leaves much to be desired. The purpose of this paper is to design a optimum ceramic recuperator, considering a high degree of transfer and according to thermal stress. A analysis model is investigated as a basis for thermodynamic associated with high-temperature recuperator, and then the analysis model is used to find the optimum design factor on the variation of recuperator condition. The result of this study are as follows : Thinner fin-plate thickness reduces pressure drop and increases heat-transfer rate, however, fin-plate having very thin thickness are difficult to manufacture and a weak thermal stress.
