The technology and apparatus were tested on a water-in-oil emulsion, where diesel fuel No. 2 was used as the oil phase and regular drinking water with a hardness salt concentration of up to 200 mg/L was used as the aqueous phase. During the design of the test bench, the latest trends in the application of emulsions as fuel were taken into account, including their use in modern diesel engines, diesel generators, industrial boilers, and turbines. For diesel engines and boilers, one of the most challenging aspects of the fuel injection and combustion process is fuel flow separation before the high-pressure pump. In this stage, the majority of the fuel flow is directed to the high-pressure pump (which today operates at pressures of 2000 bar and above) before being injected into the combustion chamber of a boiler or the cylinders of an engine, while a smaller portion is returned to the fuel tank. When using conventional single-component diesel fuel, this principle does not cause any issues. However, in the case of emulsified fuels, such a fuel supply method leads to instability in the emulsion, disrupting its homogeneity and uniform distribution of water and oil (diesel fuel) throughout the volume.
