Abstract

- The expansion of a freely bubbling fluidized bed is studied over a range of particle properties and gas velocitiesthat applies to fluidized bed boilers. A bed expansion model is derived from a modified two-phase flow model.The results from the model are compared with measurements in both a cold two-dimensional bed and a 16MW,, fluidized bed boiler, as well as with data found in the literature. The model represents experimentalresults for sand particles of a diameter ranging from 0.15 mm to 4.0 mm and with gas velocities up to 3 m s-‘.
