Carbon black reactor with improved burner

摘要

An improved carbon black process burner is disclosed which finds its preferred use in reactors for forming carbon black by the thermal decomposition of liquid hydrocarbons. The burner combusts a pre-mixed blend of fluid fuel and oxidant gas and is characterized by a flame holder having a plurality of elongated parallel orifices which produces improved combustion by inducing optimum recirculation between spaced parallel fluid jets of premixed fuel and oxidant gas issuing through the orifices. This abstract is not to be construed in any way to define or limit the invention set forth below.
