CFD Based Modelling for Predicting Fouling and Corrosion in Kraft Recovery Boilers

A. Leppänen, E. Välimäki & A. Oksanen
The aim of this paper is to present a Computational Fluid Dynamics (CFD) based modelling method for predicting fouling and corrosion in kraft recovery boiler. Kraft recovery boiler is one type of biomass­fired boilers. The modelling method combines the modelling of alkali metal chemistry as well as the formation of fine fume particles. Commercial CFD software ANSYS/FLUENT, the Fine Particle Model (FPM) extension of it, and the chemical database software FactSage are used in the...
