Abstract
A gaseous fuel burner for a carbon black reactor comprising a hollow annular metallic ring having a plurality of holes for discharge of fuel radially into a stream of combustion air immediately downstream (or upstream) of a turbulence-creating orifice. The air and fuel pass through and are intimately mixed in a cylindrical refractory mixing chamber adjacent the ring. The ring is affixed to a metallic mounting plate so that the burner and plate are cooled by incoming air supplied to a chamber located between said plate and the upstream end of the reactor.
