This paper reports new results about the combustion dynamics of hydroprocessed renewable jet fuel droplets derived from heterotrophic algae (AHRJ) burning under conditions that promote one-dimensional transport dynamics and near spherically symmetric burning conditions. Results are compared between Jet-A and three AHRJ/Jet-A mixtures containing 25, 50, and 75% AHRJ by volume. The results show that AHRJ droplets burn slightly faster than Jet-A and have a significantly reduced sooting propensity. Detailed chemical analysis also shows that AHRJ contains virtually no aromatics while the aromatic content of Jet-A was 16% by volume. The influence of composition on the burning rate is explained using a simple scaling argument that illustrates the importance of liquid density and other properties.
