NOx prediction for FBC boilers by empirical models

Popis výsledku v původním jazyce

Reliable prediction of NOX emissions can provide useful information for boiler design and fuel selection. Recently used kinetic prediction models for FBC boilers are overly complex and require large computing capacity. Even so there are many uncertainties in case of FBC boilers. Empirical modeling approach for NOX prediction has been used exclusively for PCC boilers, no reference is available for modification of this method for FBC conditions. This paper presents possible advantages of empirical modeling based prediction of NOX emissions for FBC boilers with discussion of its limitations. The empirical models are reviewed and applied to operation data from FBC boilers combusting Czech lignite coal or coal-biomass mixtures. Model modifications are proposed in accordance with theoretical knowledge and prediction accuracy.
