Multi-step-ahead prediction of NOx emissions for a coal-based boiler

► Multi-step-ahead prediction of NOx emissions, suitable for optimisation purposes. ► Feature selection and robust cross-validation of multi-step-ahead prediction. ► Comparison of linear and nonlinear modelling approaches (ARX, ARMAX, ANN, and SVR). ► Adaptive modelling of NOx emissions and its comparison with static modelling approach. ► Case study based on measured data from a power plant.
