                         The continuous rise in oil prices and the growth in environmental 
                         concerns have raised the interest for the use of biofuels, 
                         especially ethanol and biodiesel. Pure biofuels and blends of them 
                         with gasoline and diesel have been used primarily in internal 
                         combustion engines for vehicles. On the other hand, environmental 
                         legislation has become more stringent, establishing limits for 
                         pollutant emissions in engines, turbines, furnaces, boilers and 
                         industrial combustion processes. Therefore, it is of interest to 
                         the country and companies to investigate the use of biofuels in 
                         industrial applications, aiming to reduce costs, increase 
                         efficiency of operations and reduce the emission of pollutants. 
                         The objective of this work is to perform a theoretical and 
                         experimental study of a dual pressure swirl injector for 
                         atomization of biofuels. An injector prototype was built for 
                         comparative testing with distillate water, hydrated ethanol and 
                         B100 soy biodiesel. The atomization characteristics of the 
                         injector were obtained in a test bench specially developed for 
                         this research. The discharge coefficients, the average droplet 
                         diameters, the distribution of droplet sizes, the spray cone 
                         angles, the spray mass distributions, and the effects of operating 
                         pressures and mass flow rates of biofuels on the performance of 
                         the injector were determined.",
