Abstract
Combustion of Mazut in power plant generates sulfur oxides (SOx) and nitrogen oxides (NOx) that need to be controlled in accordance with the European standard. Most of the pollutant removal methods are effective in removing only one contaminant but not both SOx and NOx. In this work, a combined approach is studied to simultaneously control SOx and NOx from combustion of Mazut fuel.This combined approach is consisted of the Mazut Nano-Emulsion usage instead of regular Mazut, as well as, wet flue gas desulfurization or FGD system installation. The wet FGD system removes the SOx by 80.3% but has no influence on NOx. The water content equals to by 10% of Mazut volume is used to synthesize the Mazut Nano-Emulsion at optimum performance. The dimensions of fuel droplet are in nano scale (63.7 nm in width and 123 nm in diameter). The Mazut Nano-Emulsion usage removes the NOx and SOx by 30.8% and 42.2%, respectively. The approach of Mazut Nano-Emulsion usage and wet flue gas desulfurization leads to simultaneous reduction of SOx and NOx in accordance with the European standard. Results show that the combined approach decreases the SOx and NOx 79.8% and 78.3%, respectively that satisfied the European standard.
