A Model of the kraft recovery furnace

by Jones, Andrew K.

This thesis describes a fundamental, three-dimensional model of the kraft recovery furnace that was developed based on a finite volume solution of the governing equations for mass, momentum, energy, and species concentration for the gas phase. Bed burning and in-flight burning of liquor drops are included and affect the gas phase through source and sink terms. The model is constructed around a commercially available computational fluid dynamics code (FLUENT), with appropriate modifications to incorporate the critical features of kraft recovery furnaces.
