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.
Highlights
With the rapid economic growth around the world, the demand and competiveness for oil resources are becoming fierce
Detailed analysis for the vibrations and emissions for Jet A-1 sourced from two different suppliers, thermally stressed 100% Synthetic Paraffinic Kerosene (SPK) and Fully Formulated Synthetic Jet Fuel has been presented and compared in this work
It is observed that the different fuels produce varied power spectra from various loading
Summary
With the rapid economic growth around the world, the demand and competiveness for oil resources are becoming fierce. It has been proved that growing industrialization is damaging the climate due to the possible extinction of resources and the pollution caused by their use This has renewed the call for research into suitable alternative fuels with the aim of lowered emissions. Jet A-1 is the conventional fuel used in the aviation industry It is a kerosene type fuel having a carbon number distribution between about 8 and 16, and contains a mixture of thousands of hydrocarbons [4]. Blakey et al [5] discussed that using the 100% SPK and Fully Formulated Synthetic Jet Fuel does not reduce gas emissions as a result of carbon to hydrogen ratios and high CO2 emissions over the entire life cycle. The reduced particulate matter emission is significant with respect to the air quality
