ABSTRACT:
An apparatus for producing carbon black in which an outer housing has mounted therein a tube which defines a converging/diverging venturi through which hot combustion gases and oil flow for decomposition of the oil to carbon black. The tube has an upstream open end at which position there is a baffle having a through opening which has a diameter smaller than the diameter of the open end of the tube, thereby forming a choke at the upstream end of the tube. The apparatus is also provided with means for introducing fuel or fuel gas, air or oxygen-containing gas and feed oil at the proper positions for the manufacture of carbon black.
