COLD FLOW COMPUTATIONAL MODEL OF A RECOVERY BOILER

Preliminary computations of the cold flow in a simplified geometry of a recovery boiler are presented. The computations have been carried ou t using a new code containing multigrid methods and segmentation techn iques. This approach is shown to provide good resolution of the comple x flow near the air ports and greatly improve the convergence characte ristics of the numerical procedure. The improved resolution enhances t he predictive capabilities of the computations, and allows the assessm ent of the relative performance of different air delivery systems.
