Alternative fuels typically differ in chemical composition compared to fossil fuels. This will cause differences in the combustion performance which has a stronger impact on the continuous combustion engine than on the reciprocating engine. Thus, it is imperative to improve the knowledge of alternative fuel combustion, particularly in aviation jet engines and industrial gas turbines. The flame in such engines is aerodynamically stabilized, and even small changes in the fuel properties may have a profound impact on the flame location, stability and overall engine performance. The wider span in Cetane numbers and the slightly higher heat release of most bio-jetfuels increase the risk of thermoacoustic instabilities and potential blow-out. Recently, the Dry Low Emission (DLE) technology has been recognized by some Original Equipment Manufacturers (OEMs) as a way to reduce NOX emissions. A drawback of this technology is that it is prone to thermoacoustic instabilities, complicating the implementation of alternative turbine fuels.
