The objective of the paper consists of a theoretical prediction of radiative heat transfer in arc plasmas of SF6 (sulphur hexafluoride) with various admixtures of copper vapours. The P1-approximation was used as a mathematical tool. Due to the very complicated frequency dependence of absorption coefficients, the Planck and Rosseland mean absorption coefficients have been derived from the calculated absorption spectrum. The main radiation quantities (radiation intensity, radiation flux density and its divergence – net emission) have been determined in cylindrical arc plasmas for several model temperature profiles. Contribution to the net emission of copper admixtures is discussed. Conclusions have been made concerning validity and utilization of various absorption means.
