CFD Simulation of Co-combustion of Biomass and Coal in a Cement Calciner

Combustion of biomass and especially co-combustion of biomass and coal, are modes of fuel utilization that are increasingly gaining in significance in cement industry. One possibility for the control and investigation of the co-combustion process are CFD simulations. The purpose of this paper is to present a CFD simulation of the co-combustion of biomass and coal 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 CFD simulation. The results gained by this simulation can be used for the improving the understanding of the co-combustion process inside the calculated calciner, and for the reducing of its pollutant emissions.
