Summary

The type of fuel burnt in a gas turbine has a huge impact on PM emissions it produces. This is evident when the PM emissions from two extreme gas turbine fuels are brought into perspective. The aromatic hydrocarbon group have been widely proven to be responsible for the production PM of during combustion of liquid fuels.  Nevertheless, because of the elastomer seal swell property of aromatics, aviation fuels are specified to have 8 to 25 % by volume of aromatics.  This, poster presents emission measurement from different aromatic specie (Toluene, styrene o-xylene and ethylbenzene) and proportion blends by volume with a surrogate Jet fuel with negligible aromatic content.  The fuels were burnt in Rolls Royce Tay single can combustor with the same fuel heat input delivered. Overall, the results show an increase in PM emission levels with highest increase observed between 17.5% and 22.5% by volume of o-xylene.

The Aerosol Society recognises the importance of our diverse community and believe that to produce the best quality science we must encourage a proactive and inclusive approach to equality. This can be achieved by developing and retaining a diverse range of talented people to achieve their full potential free from discrimination. We acknowledge our role in engaging with the wider aerosol science community to develop a fair and friendly environment by promoting equality, diversity and inclusion for all, recognising that we come from varying backgrounds and experiences.
