GAS-PARTICLE INDUSTRIAL FLOW SIMULATION USING RANSTAD

A turbulent gas particle finite-volume flow simulation of a representa tive coal classifier is presented. Typical values of the loading ratio permit a one-way coupling analysis. As a case study, the computationa l fluid dynamics code, RANSTAD, and the modelling aspects are discusse d in some detail. The simulation indicates that small (approximate to 30 mu m) coal particles pass through the classifier to the furnace but that large (approximate to 300 mu m) particles are captured and remil led. The computational simulation indicates that the classifier perfor mance can be improved by internal geometric modification.
