In this study, a series of experiments have been performed to clarify the heat transfer characteristics of a multi layer type of gas-to-gas heat exchanger. The present heat exchanger is composed of two, three, four or five porous medium sections separated by opaque solid walls; that is, the low and high temperature sections in a two layer type system and the low, first and second high temperature sections with the first and second heat recovery sections in a five layer type system for instance. The key parameters in the present experiments are selected as follows; inlet gas temperature of the high temperature section : 300∿700℃(573-973 K), optical thickness of the porous medium : 0 (without porous medium) and 7.7,flow rate of low and high temperature gases : 0.35 (Nm)^3/min, flow direction of low temperature gas in the low temperature section : approaching flow.
