Carbon black reactor with axial flow burner

摘要

An improved burner for combusting gaseous fuel and oxidant gas is provided in which the fuel and oxidant gas are premixed prior to combustion by the turbulence generated by flowing the gases through a mixing zone containing a centrally disposed flow disrupting bluff body positioned in the oxidant gas stream upstream from the point of fuel injection, and a peripheral flow disrupting bluff body disposed at the periphery of the mixing zone. The burner finds particular utility in combination with other elements of a furnace-type carbon black reactor. This abstract is not to be construed in any way to define or limit the invention set forth below.
