In this paper we present the results of a 2D axisymmetric parametric study which simulates an atmospheric premixed burner with flame at high pressure, in which methane is burned. A total of nine simulations are performed with different regulators openings of primary and secondary air. Also, it provides a 3D simulation in which entry conditions are the profiles obtained in a 2D axisymmetric simulation, with the intention to note that differences are obtained between 2D and 3D simulation. The simulations are performed using the standard k-emodel for turbulence, P1 model for radiation and the Finite Rate/Eddy Dissipation model with a simplified 2-step reaction mechanism for combustion. We conclude that when the secondary air regulator is closed, combustion is incomplete. Also, the results of 2D axisymmetric are a good approximation in regards to 3D results.
