“…The use of fuel-water emulsion as a fuel, apart from the simultaneous reduction of CO and NOx emissions, also leads to a reduction of the temperature at the outlet from the combustion chamber [27,29,30]. In the presented studies, for S5 fuel, a statistically significant drop in temperature behind the combustion chamber was recorded only in two out of five measuring points (Figure 12a).…”

“…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 [25,26], a decrease in NOx emissions and an increase in CO emissions were recorded, with no increase in the temperature of the exhaust gases due to the application of FWE. On the other hand, [27] presents tests carried out on a combustion chamber normally supplied with Jet-A1 fuel, which showed a reduction in the temperature of the exhaust gases, lower NOx emission, but also a simultaneous reduction of CO emissions in the case of feeding the FWE chamber with 2.5% water content [27]. Also, in the research conducted on a miniature gas turbine fuelled by Jet-A1 and emulsion fuels with a water content of 3-12%, a simultaneous reduction in CO and NOx emissions was noted for all tested water contents in the FWE compared to the case in which TG was powered by Jet-A1 fuel.…”

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.
