NO<sub>x</sub> PREDICTION FOR FBC BOILERS USING EMPIRICAL MODELS

NO<sub>x</sub> PREDICTION FOR FBC BOILERS USING EMPIRICAL MODELS

Reliable prediction of NO<sub>x</sub> 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 the case of FBC b...

Recently used kinetic prediction models for FBC boilers are overly complex and require large computing capacity. Even so, there are many uncertainties in the case of FBC boilers. An empirical modeling approach for NO<sub>x</sub> prediction has been used exclusively for PCC boilers. No reference is available for modifying this method for FBC conditions. This paper presents possible advantages of empirical modeling based prediction of NO<sub>x</sub> emissions for FBC boilers, together with a discussion of its limitations. Empirical models are reviewed, and are applied to operation data from FBC boilers used for combusting Czech lignite coal or coal-biomass mixtures. Modifications to the model are proposed in accordance with theoretical knowledge and prediction accuracy.https://ojs.cvut.cz/ojs/index.php/ap/article/view/2059
