The performance of a cylindrical packed bed waste heat recovery sys- tem was analyzed using different mathematical models. The models were compared in terms of accuracy, precision and computational cost. Then, the best model was used to calculate the heat recovery yield and the thermal efficiency of system. The results show that the yield of heat recovery for packed bed increases when the diameter of the particles and the temperature of the inlet gas decreases. Moreover, by increasing the velocity of the inlet gas and time of heating period the yield of the system increases. The efficiency of apparatus increases by decreasing particle diameter, decreasing inlet gas velocity and increasing the inlet gas temperature.
