The numerical simulation was established by the commercial CFD code Fluent for an air jet surrounding by four fuel jets. Using a Pre PDF technique to estimate the interaction between the chemistry and turbulent flow. The simulation results show a better data of the flame temperature field characteristics and the CO, CO₂, NO H₂O, CH₄, O₂ concentrations. The influence of the velocity of the fuel and air jet on the NO production is appearing very clear.
