Soot formation in synthetic fuel droplets

Technical Report ·
OSTI ID:5315022
Fuel screening studies in the 70000 Btu/h tunnel furnace were extended to include SRC-11 middle and heavy distillate fuel oils. A total of eight fuels were investigated. Soot, particulates, and NOx emission levels were obtained under comparable firing conditions for both normal and staged combustion, and at various overall excess air levels. The combustion of single-droplet streams was investigated in a controlled flow reactor. The trajectory of every SRC-11 fuel droplet was observed to terminate in a microexplosion. High speed photography showed this to be an extremely rapid event resulting in the formation of a visible, luminous soot cloud. This behavior was not observed for a petroleum-derived No. 6 oil and appeared to be more pronounced for a blended SRC-11 than for either the middle or heavy distillate fuels. Preliminary measurements were also made of local soot concentrations and of the temprature of the soot sheet in the reactor system.
