Sažetak
Disposal of large quantities of waste has a negative effect on human health, quality of life and particularly on the environment. Due to the named negative effects the European Landfill directive (1999/31/EC), prohibits the disposal of untreated waste in landfills. Consequently, a variety of waste-to-energy technologies are the focus of many research and development activities. One of these waste-to–energy technologies is the thermal utilization of Solid Recovered Fuels – SRF. SRF is defined as solid fuels prepared from non-hazardous waste materials intended for firing in industrial furnaces. The thermal utilization of SRF, especially the co-combustion of SRF with coal is increasingly gaining on importance in cement industry. One possibility for the control and investigation of the co-combustion process are CFD simulations. Early comprehensive information, parametric studies and initial conclusions that can be gained from CFD simulations are very important in handling modern combustion units. The purpose of this paper is to present a CFD simulation of the co-combustion process in a cement calciner. Numerical models of pulverized coal and SRF combustion were developed and implemented into the commercial CFD code AVL FIRE®, which was then used for the investigation. This code was used to simulate turbulent flow field, interaction of particles with the gas phase, temperature field, and concentrations of the gaseous species and the reaction products, by solving the set of conservation equations for mass, momentum and enthalpy that govern these processes. 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 optimization of cement calciner’s operating conditions, and for the reducing of its pollutant emissions depending on coal-SRF ratio and composition of both fuels.
