“…The latest research result [49,103,104] of the Polish research team working on miniature turbine engines at the Institute of Heat Engineering of the Warsaw University of Technology bring similar results. FWEs based on the base fuel consisting of a mixture of Jet-A1 with AeroShell Turbine Oil 500 (manufactured by Shell plc) in the mass ratio of 95: 5, 2% mass addition of emulsifier to the fuel and water in the amount of up to 12% of the mass of the mixture were tested.…”

Fuel with the addition of water, forming fuel-water emulsions, is a potential way to reduce the emission of pollutants from gas turbines powered by any liquid fuel. This article analyzes the available work on the combustion of fuel-water emulsions in gas turbines. The literature analysis was preceded by a theoretical introduction on fuel-water emulsion, taking into account the factors influencing its micro- and macroscopic properties. The basic features of the agents used to stabilize the emulsion were also discussed and the process of its combustion was described. The analyzed research differed in terms of the test stands on which the experiments were conducted, the fuel constituting the continuous phase of the emulsion, the amount of water contained in the mixture and the method of producing the emulsion. On the basis of the conducted analysis, conclusions were drawn concerning the influence of feeding a gas turbine with a fuel-water emulsion on the emission of nitrogen oxides, carbon monoxide and exhaust smoke. Conclusions were formulated regarding the influence of the water additive to fuel-on-fuel consumption. In addition, the impact of the presence of water on the conversion of nitrogen contained in the fuel to nitrogen oxides was indicated, and areas requiring further research were presented.

“…It should be added that the experimental studies conducted on the influence of the emulsifier on the combustion process in miniature TG turned out to be very helpful in the context of the interpretation of the results of the research on the combustion process of the fuel-water emulsion in the TG chamber presented in the works [28][29][30], in which this emulsifier was used for creating fuel-water emulsions.…”

“…Research is also conducted on the effect of feeding gas turbines with FWE. In gas turbines (TG), there is a tendency to lower the temperature of the exhaust gases and reduce NOx emissions [25][26][27][28][29][30]. However, as is the case with reciprocating units, there are also discrepancies in the studies regarding the impact of FWE on CO emissions.…”

In an effort to reduce the emissivity of transport and energy, numerous studies are being carried out on the impact of the combustion of alternative fuels on the emission and operating parameters of propulsion and energy units. One of the observed trends is the use of emulsion fuels. The addition of an emulsifier to an emulsion fuel reduces the interfacial tension between two liquids, which allows obtaining an emulsion fuel with the expected stability. The research conducted on self-ignition engines and gas turbines (TG) does not give an unambiguous answer as to the influence of the use of fuel-water emulsion on CO emissions. One of the reasons for the discrepancy in the obtained results may be the type and amount of the emulsifier used in the emulsion fuel. Tests were carried out on the GTM-120 gas turbine to compare the operating parameters and emissions between the cases in which TG was supplied with three fuel mixtures—the standard fuel for TG (DF) and DF with 2% and 5% emulsifier addition. It was shown that the addition of 2% of the emulsifier to DF causes an increase in CO emission, with the remaining measured parameters unchanged. On the other hand, increasing the amount of emulsifier in DF to 5% reduces CO emissions to the level observed in the case in which DF was burned reduces NOx emissions and reduces the thermal efficiency of TG.
