ABSTRACT:
A research type burner is provided which permits ready optical access for study of precombustion and primary reaction zones of adiabatic flames of premixed gases. The burner includes a channel for relatively laminar gas flow having an outlet with a pair of essentially parallel closely spaced knife edges for providing an essentially stable and adiabatic flame. The knife edges project sufficiently above the burner housing to allow the passage of a laser beam between the knife edges through the zone to be studied.
