Are measurements in small-scale combustors representative of the performance of large-scale combustors with circulating fluidized bed?
Conference contribution, 1997

Comparative combustion experiments were performed in an industrial-scale combustor at the Chalmers University of Technology and in a lab-scale facility at the Technical University of Hamburg-Harburg. A comparison between the axial profiles of the concentrations of O2, CO NO, N2O and NH3 along the riser height, which were obtained during combustion of wood, peat and coal, shows basic similarity, which indicates that lab-scale combustors of suitable dimensions may be a valuable tool for the investigation of combustion phenomena. However, some significant deviations caused by three-dimensional effects in the large-scale combustor and indicate the limitations of small-scale experiments.
