摘要： A burner and method enabling operation of a post-mixed burner having radially spaced fuel and main oxidant injection points with a stable flame without the need of a separate oxidant annulus proximate the fuel stream characterized by defined relationships enabling passing stabilizing oxidant from the main oxidant stream into the fuel stream upstream of their injection into the combustion zone wherein the stabilizing oxidant velocity decreases from that of the main oxidant and the stabilizing oxidant passage flow area increases at the fuel stream communication with respect to an upstream restriction.

摘要： NOx formation in the combustion of solid hydrocarbonaceous fuel such as coal is reduced by obtaining, from the incoming feed stream of fuel solids and air, a stream having a ratio of fuel solids to air that is higher than that of the feed steam, and injecting the thus obtained stream and a small amount of oxygen to a burner where the fuel solids are combusted.

摘要： A combustion method wherein high velocity fuel is injected into a cavity recessed from a furnace zone for flow into the furnace zone, low velocity oxidant fluid is injected into the cavity for coaxial flow with the fuel, and the resulting combusting fuel and oxygen has imparted to it an angular component by operation of swirling oxygen flow and/or outwardly angled fuel flow, enabling control of the high velocity flame length.

摘要： A nozzle and gas injection method using the nozzle wherein the nozzle comprises a section of porous material. Gas passes through one or more passageways running the length of the porous material section and also diffuses through the porous material section exiting across the nozzle face. This gas passing through the face serves to keep deleterious material, such as zone vapors, from contacting and fouling the nozzle.

摘要： A plastic closure has a tamper-evident band with a 2-tier bridge arrangement comprising upper and lower bridges that are staggered circumferentially of the band. The upper bridges are spaced along an upper line of weakness and connect the tamper-evident band to the side wall of the closure, while the lower bridges are spaced along a lower line of weakness and connect a lower portion of the tamper-evident band to an upper portion of the band. The lower portion has an internal locking bead for engaging an external locking shoulder on the neck of a container. When the closure is moved in a direction to remove it from the container, the upper portion of the band is deformed into a zig-zag shape. Eventually upper bridges, which are weaker than the lower bridges, break, so that at least a top part of the closure can be removed from the container.

摘要： Method and apparatus for changing the direction of a fluid stream injected into a combustion zone wherein a flow of biasing fluid is provided to a high velocity fuel or oxidant stream in a perpendicular direction proximate the inlet of an outwardly tapered cavity, causing the fluid stream to be deflected toward a wall of the cavity and to flow in a direction along the wall by a pressure differential across the fluid stream.
