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.
