"Predictions of NOx emissions in pulverized coal

The purpose of this research work was to develop a transferable mathematically simple model which gives the possibility to make fast and easy predictions regarding the NOx emission behavior of a broad–spectrum of coals within a certain combustion environment. In this context, this thesis is a further step of a common ongoing investigation focused on predicting NOx emissions from self

Carrier-phase DNS of detailed NOx formation in early-stage

2021-5-1  Carrier-phase DNS of detailed NO x formation in pulverized coal flames with fuel-bound nitrogen was carried out in a 3D temporally evolving mixing layer. To comprehensively capture the conversion of fuel-N to NO x,both volatile-N and char-N were considered, albeit in the present setup the latter is negligible compared to the former.
