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.
