“…There are various studies in the literature regarding the overall environmental impact, global warming potential and the use of alternative fuels in gas turbines (26,(28)(29)(30)(31)(34)(35)(36)(37)(38)(39)(40)(41)(42)(43)(44)(45)(46)(47) . Recent studies by Christie et al (47) and Brem et al (26) show the impact of hydrogen content in the fuel on PM emissions.…”

There is a growing interest in the use of alternative fuels in gas turbine engines to reduce emissions. Testing of alternative fuels is expensive when done on a large-scale gas turbine engine. In this study, a re-commissioned small gas turbine auxiliary power unit (APU) has been used to test various blends of Jet A-1, synthetic paraffinic kerosene (SPK) and diesel with as well as eight other novel fuels. A detailed analysis of performance, gaseous emissions and particulate emissions has been presented in this study. It is observed that aromatic content in general as well as the particular chemical composition of the aromatic compound plays a vital role in particulate emissions generation. SPK fuel shows substantially lower particulate emissions with respect to Jet A. However, not all the species of aromatics negatively impact particulate emissions. Gaseous emissions measured are comparable for all the fuels tested in this study.

Abstract:The rapid growth of the aviation sector around the globe has witnessed an overwhelming impact on fossil fuel resources. With the implementation of stricter environmental laws over emissions by conventional jet fuels, growing demand for research on alternative fuels has become imperative. One-hundred percent Synthetic Paraffinic Kerosene (SPK) and Fully Formulated Synthetic Jet Fuel have surfaced as viable alternatives for gas turbine engines due to their similar properties as that of Jet Fuel. This paper presents results from an experimental study performed on a small gas turbine engine, comparing emissions performance and vibrations for conventional Jet A-1 Fuel, thermally stressed 100% SPK and Fully Formulated Synthetic Jet Fuel. Different vibration frequencies, power spectra were observed for different fuels. Gaseous emissions observed were nearly the same, whereas, significant changes in particulates emissions were observed.

“…Alternatives to Jet fuel come through various production pathways such as FischerTropsch process, Hydro processing and transesterification [2][3]. Fuels derived from these processes such as GTL or CTL, bio-diesels and HRJ Fuel are being tested for reduced gaseous and particulate emissions [4].…”

Stricter emissions legislation has driven the aviation industry to explore alternative fuels that can efficiently replace or blend with current Jet fuels. With this change it has become vital to investigate the effects of these fuels on combustion instabilities. In this study a recommissioned small gas turbine (Honeywell GTCP85 APU engine) has been used to test various blends of Jet A-1 and UOP along with four other novel fuels. A detailed analysis of vibrational response of these fuels upon combustion has been presented in this study. The study was conducted at the University of Sheffield's Low Carbon Combustion. The focus of this study is to investigate the vibrational response of different fuels and their compositions with varied aromatic content.
