This paper is focused on issues related to coupling of a fuel bed model with the freeboard as one of methods to simulate solid fuel combustion in grate furnaces. There are several problems, that have to be dealt with, when applying the coupled methodology, however previously not discussed in detail in literature. Topics, that are addressed, include the way of coupling, especially placement and discretization properties of the interface between the two computational models within the overall furnace model. As the bed model plays key role in this modeling approach, capabilities of existing models are reviewed. The emphasis is put on those features and problems that are not sufficiently solved in order to yield general and reliable model. One of these features is prediction of release of minor biomass and municipal solid waste constituents such as K, Cl, S and heavy metal elements as they are closely related to pollutant emissions formation and deposition, corrosion and erosion problems.
