摘要：

High-chromium containing single-phase ferritic alloy surfaces are commonly used in high-temperature radiant heating applications. The surface emissivity number at any given temperature determines the rate of conversion from internal to radiant energy. In this article, using experimental data and numerical simulations, we have determined the emissivity of a Fe-5.8 pet Al-22 pet Cr alloy surface, as a function of temperature. Experimentally measured temperature values were compared with results from numerical simulations in order to accurately determine the surface emissivity. In the temperature range of 1200 to 1350 K, the emissivity was noted to increase with temperature.
