Abstract
Process for the production of furnace black by producing a stream of hot combustion gases in a combustion chamber, feeding the hot combustion gases along a flow axis from the combustion chamber through a reactor narrow point into a reaction zone, mixing carbon black raw material into the flow of the combustion gases in front of, inside or behind the reactor narrow point and stopping carbon black formation downstream in the reaction zone by spraying in water, steam being jetted in axially through the gas burner and optionally at the radial oil nozzles and beaded carbon black being introduced before and/or after the reactor narrow point.
