As green transition in aviation continues to be pushed, SAFs becomes increasingly important. Hydrotreated Pyrolysis Oils (HPO) could potentially expand the ways SAFs could be produced. This thesis looks at the flame speed as well as NOx and CO emissions of this potential SAF when blended with Jet-A1. Experiment was performed in a bunsen burner setup, with flame speed determined from chemiluminescence images and emission data obtained from a gas analyzer. The results showed higher NOx emission, especially when equivalence ratio is close to stoichiometric condition. Higher CO was also observed for rich conditions, while no significant change in flame speed was seen. Experiment was also performed for Jet-A1 & hydrogen blend, which saw higher NO and CO emission at stoichiometric condition, and much higher flame speed.
