Sažetak
The use of waste wood biomass as fuel is increasingly gaining significance in cement industry. Combustion of biomass and particularly co-firing of biomass and coal in existing pulverized-fuel burners still faces significant challenges. A possibility for the ex-ante control and investigation of the co-firing process are Computational Fluid Dynamics - CFD simulations. The purpose of this paper is to present a numerical analysis of co-firing pulverized coal and biomass in a cement calciner. Numerical models of pulverized coal and biomass combustion were developed and implemented into a commercial computational fluid dynamics code FIRE, which was then used for the analysis. A three dimensional geometry of a real industrial cement calciner was used for the analysis. Three different co-firing cases were analysed. The results obtained from this study can be used for assessing different co-firing cases, and for improving the understanding of the co-firing process inside the calculated calciner.
