Validation and Prediction of Ultra-Low NOx Burner Performance using Computational Fluid Dynamics

Paper from the AFRC 2015 conference titled Validation and Prediction of Ultra-Low NOx Burner Performance using Computational Fluid Dynamics

Computational Fluid Dynamics (CFD) modelling and simulations were performed to evaluate and; predict the performance of an ultra-low NOx burner design. CFD model validation using; experimental results was performed to evaluate model settings and parameters. The validation; showed a good trend agreement with the experimental results and provided confidence in the; model that it can be used to predict the burner performance.; Geometric changes were made to the model and simulations were performed to predict the; performance and emissions of the burner. The CFD model prediction was performed and testing; was conducted for these data points. Results indicated that the prediction trend was in good; agreement with the follow-on experimental testing verifying the robustness of the CFD model to; predict outcomes in an accurate and meaningful way. These results of the model development for; the ultra-low NOx burner will be presented.
