An experimental study was conducted of the atomization characteristics of a Y shaped twin fluid nozzle used for lime slurry atomization. An analysis was performed of the various factors liable to influence the atomization angle and the distribution of Sauter mean diameter (SMD) of the atomized spray drop. An empiric formula for predicting spray drop average diameter has also been obtained. The results of the study indicate that the nozzle under investigation features low power consumption and high atomization effectiveness, making it especially suitable for flue gas desulfurization based on a semi dry method.
