Abstract:
1. A process for the production of furnace black in a furnace black reactor having a flow axis, a gas burner, a combustion chamber, a reactor narrow point and a reaction zone, said process comprising: introducing fuel and combustion air into said gas burner, introducing steam axially into said gas burner by means of an axial lance upstream from said reactor narrow point, and jetting said steam axially through said gas burner, producing thereby a flow of hot combustion gases which flows into said combustion chamber of said reactor, feeding the hot combustion gases along said flow axis from the combustion chamber through a reactor narrow point into a reaction zone, mixing beaded carbon black into the flow of hot combustion gases before and/or after the reactor narrow point and stopping carbon black formation downstream in the reaction zone by spraying in water.
