Abstract: PROBLEM TO BE SOLVED: To provide a process in which deep-coloured furnace blacks can be produced directly in the furnace reactor. SOLUTION: The 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 of the reactor narrow point and stopping carbon black formation downstream in the reaction zone by spraying in water, steam being jetted 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.

Abstract: The present invention relates to a tubular furnace having a restriction. In at least the latter's region there is ejectably disposed along the reactor axis an atomizing device for crude furnace black. Ahead of the restriction a combustion chamber for producing the pyrolysis medium for the crude furnace black has been added laterally. The center lines of reactor tube and combustion chamber lie in the same plane and are superposed substantially at right angles. Furthermore, a process for producing furnace blacks in which said reactor can be applied is described.

Abstract: Furnace black is produced in a furnace black reactor having flow axis by introducing fuel and combustion air into a gas burner (5) and jetting steam axially through the gas burner; and producing a flow of hot combustion gases in a combustion chamber (1) of the reactor. Production of furnace black in a furnace black reactor having flow axis involves introducing fuel and combustion air into a gas burner and jetting steam axially through the gas burner; and producing flow of hot combustion gases in a combustion chamber of the reactor, feeding the hot combustion gases along the flow axis from the combustion chamber through a reactor narrow point into a reaction zone (3), mixing beaded carbon black raw material into the flow of hot combustion gases upstream of inside or downstream of the reactor narrow point, and stopping carbon black formation downstream in the reaction zone through spraying in water.

Abstract: Procedimiento para la fabricación de negro de horno generando una corriente de gases de combustión calientes en una cámara de combustión, conduciendo los gases de combustión calientes a lo largo de un eje de flujo desde la cámara de combustión y a través de una zona de estrangulamiento del reactor hasta una zona de reacción, mezclando la materia prima para hollín con la corriente de gases de combustión delante, dentro o detrás de la zona de estrangulamiento del reactor y deteniendo la formación de hollín corriente abajo en la zona de reacción pulverizando agua, caracterizado porque axialmente a través del quemador de gas y dado el caso en las tubuladuras radiales de alimentación de aceite se inyecta vapor de agua y delante y/o detrás de la zona de estrangulamiento del reactor se introduce negro perlado.

Abstract: A reactor for the mfr. of furnace black is fitted with a combustion chamber which is joined at its open end with the first section of the reactor tube. Its axis lies in the same plane as that of the reactor tube and both axes are pref. arranged perpendicular to each other. The reactor part is lined with an insulating layer and a refractory ceramic layer. Its first section has a cover plate for an oil lance and a recess for the combustion chamber. The second section is waisted and the third section has channels for the insertion of coolant pipes with spray nozzles.

Abstract: A tubular furnace as a reactor for producing carbon black is disclosed having a constriction in at least the area of the spray device for the carbon black starting material which is oriented along the reactor axis. A combustion chamber for generating the gaseous pyrolysis medium for the carbon black raw material is laterally located in front of the constriction. The central axes of the reactor tube and the combustion chamber are in the same plane and are essentially at right angles to one another. In addition, a method for producing furnace carbon blacks is disclosed in which the described reactor can be used.
