Abstract : For calculation of the mean temperature difference in convective bundles with gas radiation, use is made of an equation containing the temperatures of the gases before and after the convective bundle, and the saturation temperature at a given vapor pressure. This equation is approximate, since its degree of accuracy decreases with an increase in gas radiation. The present article is an attempt to demonstrate mathematically that introduction of a correction factor can increase the accuracy of the calculation.
