Method and apparatus for fine-tuning in carbon black production

摘要

A method and apparatus for producing carbon black under fine-tuned conditions which comprises measuring a property of the black produced in a tangential introduction of hot gases to produce a vortex operation and adjusting introduction of the hot gases and/or the make oil or gas responsive to said property until it has a desired value. In one embodiment, the adjustment is made manually. In another embodiment, it can be made by a computerized operation. The point of introduction of hot gases can be adjusted by providing at least one movable orifice-carrying element in the conduit supplying the hot combustion gases. The discharge end of the make oil or gas supply pipe can also be relocated according to the measured property.
