Abstract
Due to the continuous increase in oil prices and the fact that environmental legislation has become increasingly rigorous, recommending strict limits for pollutant emissions in engines, turbines, furnaces, boilers and industrial combustion processes, it is verified that is in the best interest of the country and companies to investigate the use of biofuels such as mixtures of these fuels with fossil fuels in industrial applications, aiming to reduce costs, increase the efficiency of operations, and reduce the emission of pollutants. Combustion of liquid fuels depends on efficient atomization to increase the surface area of the fuel and thus achieve high rates of mixing and evaporation. In order to promote combustion with maximum efficiency and minimum emission of pollutants, an injector must provide a fuel spray that evaporates and disperses rapidly to produce a homogeneous mixture of vaporized fuel and air. Since a significant portion of the industrial combustors operate with liquid fuels and the injector is a fundamental part in combustion systems using such fuels, the present work aims designing a Y-jet injector for the atomization of fuel blends that will be used in future applications for combustion systems. However, the purpose of this work is to determine the theoretical median mass diameter (MMD) and the theoretical Sauter mean diameter for different blends of biofuels (soybean biodiesel and bovine tallow and hydrated ethanol) and conventional fuels (common gasoline) for different ratios of mixtures.
