NOx Modelling and Prediction

DATE: April 2000

This report discusses the development of modelling and prediction methods for estimating and minimising the level of NOx production during the combustion of pulverised coal. Current approaches include the use of computational fluid dynamics (CFD), kinetic and chemical engineering models, quantitative and empirical relationships and artificial intelligence methods. Applications of the CFD-based modelling approaches for designing new plants or modifying existing ones as well as for the simulation of pilot-scale burners and full-scale boilers are detailed. The current capabilities and limitations of CFD for accurately predicting levels of NOx production during coal combustion are also discussed.
