Submerged combustion burners having a burner body and a burner tip connected thereto. The burner body has an external conduit and first and second internal conduits substantially concentric therewith, forming first and second annuli for passing a cooling fluid therethrough. A burner tip body is connected to the burner body at ends of the external and second internal conduits. The burner tip includes a generally central flow passage for a combustible mixture, the flow passage defined by an inner wall of the burner tip. The burner tip further has an outer wall and a crown connecting the inner and outer walls. The inner and outer walls, and the crown are comprised of same or different materials having greater corrosion and/or fatigue resistance than at least the external burner conduit.

A nonwoven fibrous insulation product has at least a bi-modal fiber diameter distribution designed to provide the product with selected thermal insulating and physical performance properties that are affected by fiber diameter such as rigidity and recovery properties. The product is made by: forming two or more fiber groupings that each have a selected fiber diameter distribution with a selected mean fiber diameter wherein the selected fiber diameter distributions of the fiber groupings differ from each other. The fibers of the fiber groupings are intermingled and entangled together in selected percentages by weight to form a product with a selected density and thickness that exhibits selected product performance properties based on the properties of the fiber groupings and the relative percentages by weight of the fiber groupings.

Fibrous product and method and apparatus for making the product

An exemplary bushing system utilizes a bushing having a bottom plate having a plurality of holes from which filaments are drawn, and a plurality of support-receiving elements that are each configured to receive an elongated support. The support-receiving elements extend through the bushing generally along a longitudinal axis. A frame supports the bushing and includes a pair of horizontal rails upon which the supports rest. The horizontal rails comprise a treated surface that permits movement of the elongated supports relative to the frame in the longitudinal direction as the bushing expands and contracts due to thermal heating and cooling.

Transverse row bushings and methods with freedom of movement

A bushing system includes a bushing having a bottom plate with a plurality of holes from which filaments are drawn. At least one elongated support extends through the bushing generally along a longitudinal axis to hold and stabilize the bushing. To handle the harsh conditions under which the bushing is subjected, the support comprises an alumina-based ceramic that generally resists sagging or excessive expansion and contraction during heating and cooling.

According to the invention, a system for forming glass fiber from molten glass is disclosed. The system may include a tip plate, a plurality of tips, and a plurality of support members. The plurality of tips may include a plurality of rows of tips. Each of the plurality of support members may support the tip plate. Each of the plurality of support members may be located between two of the plurality of rows of tips.

Tubular pipe insulation is made from a glass fiber mat produced utilizing a rotary glass fiberization process. A spinner disc is rotated to centrifuge molten glass through fiberization holes in an annular sidewall of the spinner disc and form primary glass fibers. The primary glass fibers are attenuated and formed into a veil where the fibers are dispersed to reduce in length the fiber networks formed from the fibers. Binder is applied to the fibers and the fibers are collected into a mat that, when pulled apart by longitudinally directed, opposing forces, separates across the width of the mat into two mat sections having feathered edges with substantially no fibrous stringers extending beyond the feathered edges for a distance greater than about four inches. The leading mat section is then wound about a mandrel and the binder in the mat is cured to form the pipe insulation.

Fiberizing bushings for fiberizing molten materials including molten glass are heated by applying a voltage drop across the bushings wherein molten material flows through an array of hollow tips attached to, or integral with, a tip plate having orifices therein that generally align with channels through the hollow tips to form fibers. The uniformity of the diameter of the fibers produced is much improved by using tips of different lengths and/or tips having channels of differing ID's to compensate for unequal electrical heating and/or cooling effects of drawn-in ambient air that cools the tips on the extreme outer periphery and/or cooling or heating effects of external supports or cooling members running through the array of tips that cools or heats adjacent tips more than the interior tips.

A method of reducing carbon monoxide and hydrocarbon emissions in a rotary glass fiberization process utilizes a fiberizing spinner with fiberizing holes through which molten glass is passed by centrifugal force to form primary fibers which pass through an annular heat bath region and attenuation fluid emitting apparatus that forcefully emits an attenuating fluid to attenuate the primary fibers into finer diameter fibers. Oxygen is introduced into the annular heat bath region to oxygen enrich the annular heat bath region and is combusted in the annular heat bath region to materially reduce carbon monoxide and unburned hydrocarbon emissions produced by the process.

A mixture of natural gas and air is converted to a C&#x2013;Cdiesel fuel-grade liquid hydrocarbon. The natural gas and air mixture is supplied to the input of a catalytic partial oxidation reactor. The carbon-containing gas output of the catalytic partial oxidation reactor is connected as an input to a first Fischer-Tropsch reactor, to thereby form a first diesel fuel grade C&#x2013;Cliquid hydrocarbon output. A carbon-containing gas output of the first Fischer-Tropsch reactor is connected to the input of a second Fischer-Tropsch reactor, to thereby form a second diesel fuel grade C&#x2013;Cliquid hydrocarbon output. The catalytic partial oxidation reactor contains a platinum group catalyst, a promoted platinum group catalyst, a rhodium catalyst, or a platinum promoted rhodium catalyst. Each of the Fischer-Tropsch reactors contain a catalyst that is made up of from about 3 to about 60 parts-by-weight cobalt and from about 0.1 to about 100 parts-by-weight of at least one metal selected from a group consisting of cerium, lanthanum and ruthenium per 100 parts-by-weight of a support selected from a group consisting of silica, alumina and combinations of silica and alumina, and more preferably a catalyst that is made up of about 20 percent by weight cobalt, about 0.1 percent by weight ruthenium, about 0.1 percent by weight platinum, the remainder being an alumina support.
