Abstract
The operational life of a synthesis gas generation reactor burner nozzle is improved, at least about 14%, by a faired lip around the nozzle discharge orifice projecting about 0.95 cm from the nozzle end face. The lip is faired with a 45.degree. conical angle from the nozzle face. A smooth transition of recirculated gas flow across the nozzle face into the reactive material discharge column is believed to promote an attached static or laminar flowing boundary layer of cooled gas that insulates the nozzle face, to a degree, from the emissive heat of the combustion reaction.
