Approaches to solid fuel combustion modelling in experimental reactor

Popis výsledku v původním jazyce

The modelling of combustion in furnaces and boilers by computational fluid dynamics (CFD) approaches has become a standard tool in engineering practice. However, the simulations of some types of combustion units including grate furnaces are rare, mainlydue to the difficulties presented by fixed-bed combustion process. In this work, we provide an assessment of existing simplified approaches to the fixed bed modelling that are manageable with the use of tools available in commercial CFD software, in ourcase FLUENT v 6.3. The approaches are applied to the simulation of a preliminary design of an experimental fixed-bed reactor. The approaches discussed differ mainly by the complexity of treatment of the solid fuel layer, but also by the degree of interaction between the fixed bed and the freeboard region. The present article provides a review of grate bed modelling with focus on differences between various approaches to bed and chamber freeboard model.
