Definitions

  • each of these fuel-oil pipes being equipped with a spray nozzle inclined at an angle with respect to the axis of the center pipe.
  • These fuel-oil pipes are for the introduction of combustion fuel into the reactor.
  • the assembly also includes a substantially cone-shaped iiameholder device mounted concentrically about the third pipe at the end thereof, such cone flaring outwardly toward the interior of the reactor, such cone being comprised of a plurality of vanes or louvers each of which is twisted at the outer ends thereof.
  • This invention relates to the production of carbon black by the injection of a suitable hydrocarbon feedstock into an elongate reactor or combustion chamber containing high-temperature llames and gases, and more particularly to a burner and feedstock injection assembly for burning a normally liquid hydrocarbon as fuel to provide the heat necessary for the pyrolysis of the feedstock to form carbon black.
  • Such assembly also includes means for supplying the feedstock to the reactor.
  • gas is used as a fuel to the burner; however, in situations where gas is not available, or is not available at an economical price, it is desirable to have a burner which is designed for the use of a normally liquid hydrocarbon fuel.
  • the main object of this invention is to provide a burner which will operate satisfactorily on a normally liquid fuel rather than gas.
