Sažetak
Within the industrial sector, the cement industry is considered as one of the largest pollutant emitters with nearly 5 – 8 % of global CO2 emissions. One way to cope with high pollutant emissions is to co‐combust biomass with pulverized coal. In this work, the mathematical model was developed and implemented into the commercial CFD code AVL FIRE®. The model is detailed enough to take into account the complex physical and chemical behavior of the co‐combustion process, while on the other hand, the model is simple enough to perform simulations with a real geometry of cement rotary kiln within a reasonable computational time. Numerical simulation with a 20% share of pulverized biomass of total fuel heating value was performed. An industrial rotary kiln geometry was simulated, and temperature and velocity fields along with mass fractions of released volatiles and combustion products were analyzed. Presented results showed that the developed model can be used for getting better insights in the complex co‐ firing process with the main objective to reduce CO2 emissions by optimizing the combustion process inside the rotary kiln.
