Calculation of the optical characteristics of radiation heat transfer in furnace chambers

A software system for calculating the problems of radiation heat transfer in two-phase media is considered. Results of the calculation of a radiation field in the combustion chamber of a specific steam generator are presented.Notation I(x, y, ) spectral intensity of radiation at the point (x, y) in the direction - B(T) spectral intensity of black body radiation at the temperature T=T(x, y) - , spectral coefficients of absorption and scattering of radiation - external normal to the boundary of the region - and T spectral emissivity factor and temperature of the heat-absorbing surface - Q density of the radiation flux incident on the chamber heat-absorbing surface Academic Scientific Complex A.
