Abstract

CFD modeling is commonly used in furnace design, e.g. for pulverized coal boilers. There the gas flow can be simulated with a steady-state model and the fuel particles by tracking their paths. For CFBs this type of Eulerian-Lagrangian approach is not feasible. Instead, it is possible to apply an Eulerian-Eulerian steady-state two-fluid model combined with Lagrangian particle tracking for the fuel. The present paper concerns the steady-state CFD modeling of CFBs based on this approach, with emphasis on how furnace size affects the closure of the balance equations. The effects of the furnace dimensions on the flow patterns and equation closures are shown to be significant.
