<p>The disclosed apparatus is of the type in which feed units feed air and hydrocarbon material into a reaction chamber, where they react to form carbon black. A filter then removes the carbon black. Disclosed is the provision of a mixing chamber between the feed units and the reaction chamber. The mixing chambers pass through a demountable hollow reactor cover through which there is circulated a heat transfer fluid for controlling the temperature of the mixing chamber walls. The mixing chamber can be common to a plurality of feed units or be separate for each feed unit. Also disclosed is a feed unit which has a vortex plate, an output nozzle, and a hydrocarbon spray nozzle, all mounted on a hydrocarbon supply tube which in turn is fixed to a demountable cover of the feed unit. This permits these components to be readily removed with the cover for replacement or service. The feed units can also have their temperature controlled by the heat transfer fluid for the mixing chambers. August 18, 1978</p> |
