A Premixed Flamelet−PDF Model for Biomass

2019-5-26 · In this paper, a new modeling approach for biomass furnaces is presented. A flamelet model is applied for the prediction of combustion and NOx emissions in a pilot-scale low-NOx biomass grate furnace. The model describes the combustion chemistry using premixed flamelets. The chemical system is mapped on three control variables—the mixture fraction, enthalpy, and a reaction progress variable
