In this paper we present some results of parametric studies of the effect of radiation on the width of the chamber combustion aerodynamics and thermal characteristics of tube furnaces with fan-shaped near-wall flame gas burners . The problem is considered in the differential thermal analysis method inserts. The processes occurring in the cell radiation simulated two-dimensional equation s of energy, transfer of radiation , movement, k - e of model of turbulence and the simple model of natural gas burning . Radiated heat transfer is considered within S 2 approach for the method of discrete ordinates. The results of numerical studies of the effect of radiation on the width of the chamber form streamlines the flue gas to the distribution of the surface density of the radiant heat flux to the tubular screen on temperature change inside surface of the side lining and the gas temperature at the furnace height.
