Abstract The natural gas industry is currently involved in the development of new burner technology to produce efficient, very low emission burners for industrial and utility applications. Evaluation of new designs becomes increasingly cost intensive as new burner designs extend outside existing operating envelopes. Numerical combustion modeling is evolving as a standard tool to reduce design cycle time and focus test programs. Models currently in use are based largely on the fundamental description of the complex interacting processes that occur during fossil fuel combustion: turbulent flow, gas phase chemical reaction and heat transfer. However, representation of some of these phenomena still requires the use of empirical models to close physically based equations or to permit predictions to be completed in practical time frames. Because of these limitations, these models must be thoroughly validated and their range of application understood before they can be routinely applied. The validation process requires access to high-quality experimental data in key areas of the flame, with complete information on geometry, operating conditions, and boundary conditions which play a strong role in modeling predictions. To construct a comprehensive validation document for use by the natural gas industry, Gas Research Institute has funded a joint effort between Babcock and Wilcox and the Burner Engineering Research Laboratory (BERL) at Sandia National Laboratories. Key project goals are the collection of a definitive set of measurements for an industrial natural gas flame, and the documentation of the test cases for model validation. To ensure the viability of this data for model validation, combustion models have been applied throughout the program. In particular, modeling was used to guide the test plan, focus measurement requirements, and evaluate the data for validation use. The tests and the use of models to drive the test campaign are discussed. Predictions are compared with the collected data. Modeling strengths and remaining challenges are discussed in terms of design application to industrial burners. The need for additional validation efforts is addressed.
