Sažetak
The article deals with analysis of a possible application of high-power ultrasound in the process of preparing homogeneous emulsions of fuel and water in order to improve combustion efficiency on ships and generaly in shipbuilding industry. On the basis of published literature it is known that under influence of the high-power ultrasound it is possible to disperse water droplets in waste oil or high viscosity liquid fuels (for example crude oil) and high quality emulsions can be obtained. Under influence of ultrasound it is possible to perform emulsification and homogenization of immiscible liquids in such way that even after long time period eventual component separation could be avoided. Evaporation of emulsified water reduces the combustion temperature and ensures better "contact" of the fuel droplets with the oxygen, which enhances the combustion by reduction of soot and NOx in exhaust gases.
