Many aspects of boiler operation may be affected by a low-NO{sub x} combustion system including combustion efficiency, heat transfer and corrosion potential. Mathematical modeling provides the means to evaluate the impact of low-NO{sub x} combustion systems on boiler combustion efficiency, heat transfer performance and life. Babcock and Wilcox`s mathematical flow, combustion and heat transfer models were used during a Clean Coal Technology Demonstration project to assist the application of a novel pulverized coal burner technology. The models were used extensively in the development of the burner and to evaluate the impact on furnace performance during the full-scale demonstration. The objective of the modeling task was to provide a validated tool that could be used to assist the commercialization of the new technology. To validate the models, the predictions with the original cell burners and the new Low-NO{sub x} Cell{trademark} burners were compared with measurements taken during the baseline and post-retrofit tests. Probing was conducted through observation ports at the furnace exit and at a plane 12 m (40 ft) above the burners. Velocity, temperature, and gas species measurements were made at two boiler loads. The comparison between the predictions and the data is presented and discussed.
