An innovative Emulsification Engine Feeding System (EEFS) has been developed in the Roma Tre University Fluid Machinery Lab. It is based on an emulsification loop, where fuel and water are fed in real time with the emulsion injection. Thus no chemicals to stabilize water in diesel fuel or ethanol in diesel fuel emulsions, are used. The system assures a sufficient stability level of the emulsion to be injected inside the combustor. Tests carried out on the EEFS, developed for a 250-300 kW gas turbine have shown the good quality of the emulsion in terms of the water droplet diameters and volumetric mixing ratio at the various engine loadings. A water separation section that operates for the duration of the engine shutdown is an unique feature of the EEFS to avoid corrosion during stops.
