PERFORMANCE AND EMISSIONS OF A VESSEL TURBINE FUELED WITH MARINE AND ASPIRE OIL METHYL ESTER MIXTURES

In this experimental case, a vessel G/T was run with marine fuel (MF)/aspires oil methyl ester (AME) mixtures. The blends tested were marine fuel (MF), 50 % of aspire oil methyl ester, 100 % of aspire oil methyl ester (AME), and 100 % of MF by volume. The G/T was operated at 4 loads, 20 %, 60 %, 80 % and 100 %. Turbine power generation and emissions performance were tested. The results that AME content in the fuel mixture increased, the fuel flow rate increased to maintain the constant speed operation and equivalence ratio reduced. The results of tested that turbine can operate with AME blends in MF without any modification. Exhaust gas temperatures reduced with increasing AME content. Higher AME blends resulted in lower CO2, CO emissions while NOx emissions increasing. Finally, various energetic performance parameters of the engine were evaluated and compared with each other. This study shows that a turbine engine can be operated successfully with marine fuel (MF) and aspire oil methyl ester (AME) mixtures.
