Grate Furnace Combustion: A Submodel for the Solid Fuel Layer

摘要

The reduction of NO_x formation in biomass-fired grate furnaces requires the development of numerical models. An essential part of such a model is the submodel for the conversion of the solid fuel on the grate. The submodel presented is able to predict the velocity of the conversion front as well as spatial profiles of porosity, species mass fraction and temperature. The possibility to make use of detailed kinetic mechanisms previously applied only for gas-phase combustion processes is a new feature of our model. Application of these mechanisms is essential step for future toward future NO_x predictions.
