Abstract
Complex heat transfer in radiant chambers of technological furnaces of the petrochemical industry is considered. The object of research is a vertically located flat channel, approximately simulating a radiant chamber. The walls of the channel are formed by a refractory lining and a tubular screen with a known temperature. The chamber volume is filled with selectively emitting, absorbing and weakly scattering media of gaseous fuel combustion products. The research method is based on the numerical solution of two-dimensional integro-differential equations of radiation gas dynamics, closed by a two-parameter model of turbulent convection. The influence of the modes of organization of the combustion process, the radiation properties of the combustion products and refractory lining on the distribution of heat fluxes and the characteristics of the total heat transfer are considered.
