Within a differential method of thermal calculation of fire chambers influence of an arrangement of fan torches circles on thermal characteristics of tubular furnaces is investigated. The processes proceeding in the furnace camera, are modelled by the two-dimensional equations of energy, transfer of radiation, movement, k-ε model of turbulence and two-step model of natural gas burning. Transfer of radiation is considered within of approach of a method of discrete ordinates. Results of numerical researches are given .
