A simplified mathematical model for solving the conjugate heat transfer problem in the anode baking furnace is developed。 The air motion in the flue induced by the exhaust draft is described by the system of differential equations for the viscous compressible multicomponent gas taking into account heat and mass transfer。 The flow is turbulent and the κ-ε model is used。 Turbulence-controlled eddy break-up model governs the combustion。 The diffuse method is used for calculating the radiation flux。 It is shown that the problem can be simplified if we treat the processes in the flue as stationary and solve the transient thermal conductivity equation only in the pit。 The fields of pressure， velocity， temperature and concentrations are obtained in the flue and time dependent temperature distributions for each of the baking anodes evaluated。
