An oxidizer head assembly includes a head body defining an inlet flange, an outlet flange, and a wall, where the inlet flange, the outlet flange, and the wall define a cavity positioned between the inlet flange and the outlet flange, a plurality of nozzles extending through the cavity, a fuel inlet in communication with the plurality of nozzles, where a fuel passes through the fuel inlet and the plurality of nozzles, a shield gas inlet in communication with the cavity, and a porous diffuser plate extending across the outlet opening, the porous diffuser plate including apertures for the plurality of nozzles and a plurality of pores, where a shield gas passes through the shield gas inlet, through the cavity, and through the plurality of pores of the porous diffuser plate around the plurality of nozzles.

Abatement systems including an oxidizer head assembly and methods for using the same

A method of forming an optical fiber preform includes the steps: igniting a burner having a fume tube assembly to produce a first spray size of silicon dioxide particles; depositing the silicon dioxide particles on a core cane to produce a soot blank; and adjusting an effective diameter of an aperture of the fume tube assembly to produce a second spray size of the silicon dioxide particles. The second spray size is larger than the first spray size.

Adjustable fume tube burner

An optical fiber production system and method are provided for producing optical fiber. An optical fiber is drawn from a preform in a furnace and passes through a treatment device under a reduced pressure in the range of 0.01 to 0.80 atm. The treatment device cools the bare optical fiber as it cools to a temperature in the range of at least 1,600&#xb0; C. to 1,300&#xb0; C. A non-contact fiber centering device is located near an exit of the treatment device to provide centering of the optical fiber as it exits the treatment device.

Method for producing optical fiber at reduced pressure

A method for producing a coated optical fiber may include drawing an optical fiber from a draw furnace along a first vertical pathway. The optical fiber may then be routed through at least one fluid bearing thereby redirecting the optical fiber along a second vertical pathway. Thereafter, a thermoplastic coating may be applied to the optical fiber with a thermoplastic coating system. The optical fiber may then be wound onto a fiber storage spool with a fiber take-up system. The fiber take-up system may be space apart from the thermoplastic coating system such that the thermoplastic coating may be cooled before the optical fiber is wound onto the fiber storage spool.

Methods and systems for producing thermoplastic coated optical fibers

Methods for producing a coated optical fiber may include drawing an optical fiber from a draw furnace along a first pathway and redirecting the optical fiber along a second, different pathway which is non-parallel with the first pathway. The optical fiber may be coated as it travels along the second pathway.

Methods and systems for producing a coated optical fibers

Methods for producing optical fibers along nonlinear paths include incorporating fluid bearings. An optical fiber is drawn from a preform along a first pathway, contacted with a region of fluid cushion of a fluid bearing, and redirected along a second pathway as the fiber is drawn across said region of fluid cushion.

Methods for drawing optical fibers using a fluid bearing

A method and apparatus for rapidly forming a porous glass preform is provided in which an array of burners is oscillated along a path parallel to the longitudinal axis of the preform. Unlike existing soot deposition techniques, the oscillation amplitude is limited so that each burner deposits soot on only a portion of the preform, e.g., 20% of the preform. By controlling inter-burner variability and the air flow in the burner-array/preform region, preforms having substantially uniform axial properties are obtained notwithstanding the fact that different burners are used to laydown different parts of the preform.
