Abstract
Optimizing and reducing the fuel consumption and thus preserving national economic resources is one of the important goals in the economy of any country. Using the natural gas instead of liquefied petroleum fuels and reducing energy consumption in industries such as cement can be a practical solution to meet the above-mentioned goals. In this study, numerical simulations are performed to enhance combustion and calcination processes in the Hormozgan cement plant calciner. To such aim, various optimizations are carried out to replace highly pollutive expensive, mazot fuel with natural gas and to improve calcination and combustion processes. Obtained results show that proposed modifications give the calciner the capability to be operated by 100% natural gas, while they reduce the energy consumption and pollutant emissions significantly. Finally, the best proposed case is implemented in the cement calciner to replace mazot by natural gas and reduce energy consumption and pollutant emissions. Site data clearly validate the proposed modifications to be effective enough to achieve all the objectives of the project.
