Abstract
In order to use CFD as cost-efficient tool for the design of biomass furnaces, a test of the simulation results is necessary. The present work considers the verification of the whole CFD model (combination of empirical fixed bed model and CFD sub-models) as well as the calibration of an empirical constant of the Eddy Dissipation combustion model. A number of test runs were performed at a biomass furnace with the two fuels fibreboard and wood chips as a reference. The species concentrations and temperatures were measured in-situ at three locations. Taking into consideration possible measurement uncertainties, the simulation results are reasonably accurate for the development of biomass grate furnaces. Moreover, by means of a modification of the Magnussen Constant, the accuracy of the simulation could be significantly improved. [18 Refs; In English]
