In this study, COMSOL Multiphysics is applied in order to simulate reacting flows for duct burner systems arranged in the post-firing section of a Heat Recovery Steam Generator of a combined cycle power plant.
Two- and three-dimensional simulations are carried out in order to investigate on operative conditions mainly responsible of duct burners overheating.
The results are obtained for several chemical compositions of the supplied fuel and for several values of the fuel mass flow rate incoming inside the control volume.
