Abstract: A gas burner apparatus for discharging a mixture of fuel gas, air and flue gas into a furnace space of a furnace wherein the mixture is burned and flue gas having a low content of nitrous oxides and carbon monoxide is formed is provided. The burner tile includes at least one gas circulation port extending though the wall of the tile. The interior surface of the wall of the tile includes a Coanda surface. Fuel gas and/or flue gas conducted through the gas circulation port follows the path of the Coanda surface which allows more flue gas to be introduced into the stream. The exterior surface of the wall of the tile also includes a Coanda surface for facilitating the creation of a staged combustion zone. Also provided are improved burner tiles, improved gas tips and methods of burning a mixture of air, fuel gas and flue gas in a furnace space.

Abstract: A flare burner that is particularly suitable for use in connection with ground flares and other types of flares in which it is important to control the height of the flame envelope created by the burner is provided. The flare burner includes a pre-mix zone including a pre-mix chamber into which air is entrained. A uniform mixture of fuel and air is formed in the pre-mix zone and caused to exit an air/fuel outlet in the top of the pre-mix chamber. In one embodiment, the amount of air in the fuel/air mixture that exits the air/fuel outlet is in excess of the stoichiometric amount of air required to support combustion of the fuel in the mixture. Fuel is injected around the perimeter of the air/fuel outlet, combustion is initiated and a flame envelope is created. By injecting a mixture of fuel and air that includes excess air into the center of the flame envelope, combustion of the central portion of the flame envelope is accelerated which allows more fuel to be flared with a given flame envelope height.

Abstract: A flare apparatus for burning combustible gases. A flare tip unit comprises an inner member and an outer member defining an annulus therebetween. The annulus defines an annular gas passage through which combustible gas passes. Air moved by a motive force, preferably steam, passes through the inner member and a steam/air mixture exits an outlet of the inner member. The combustible gas and an air/steam mixture mixes in a premix zone between the inner member outlet and the exit opening of the outer member. The combustible gas/air/steam mixture is ignited for burning in the atmosphere above the exit opening. The flare apparatus may include a plurality of flare tip units.

Abstract: Linear Coanda flare apparatus for burning pressurized waste flammable gas are disclosed. The flare apparatus basically comprises an elongated closed end pipe connected to a waste flammable gas supply pipe and having an elongated linear opening therein; and an elongated flammable gas distributor trough positioned adjacent to the elongated linear opening in the closed end pipe with the sides of the distributor trough being positioned adjacent to the outer curved surfaces of the closed end pipe thereby forming slots that discharge pressurized waste flammable gas from inside the closed end pipe over the outer curved surfaces of the closed end pipe.

Abstract: Compositions and methods are provided for the clinical assessment, diagnosis, and treatment of multiple sclerosis. The compositions of the invention are molecules related to the 21.5 kDa fetal isoform of human myelin basic protein, and include nucleic acids and polypeptides. The nucleic acid molecules of the invention are useful in the efficient production of modified and unmodified 21.5 kDa myelin basic protein polypeptides, such polypeptides being useful for assaying T cells for responsiveness to myelin basic protein epitopes. The polypeptides of the invention are also useful as therapeutic agents that act by inducing T cell responses, including apoptosis, as a means of treating multiple sclerosis.

Abstract: A liner hanger having a mechanical coupling between a liner hanger body and one or more cones is disclosed. The cones are coupled to the liner hanger body to resist axial and relative rotational movement without welding the cones to the hanger body, and without the need to use integral cones. In general, the mechanical coupling includes a hanger body or casing mandrel, a cone assembly journaled on the casing mandrel, at least one slot or groove in an outer wall of the casing mandrel, and at least one partially or fully annular slot on the inside surface of the cone assembly oriented to correspond with the groove(s) in the outer wall of the hanger body. At least one wire, or one or more bearings, is situated in the corresponding slot and the groove. The wire engages the flanks of the slot and groove sufficiently to resist axial or rotational movement of the cones relative to the hanger body.
