摘要： An atomizing nozzle assembly is provided having an outwardly diverging frustrum of a cone shaped, deflector core of wear resistant ceramic, a nozzle rim of wear resistant ceramic encircling the core and coextensive with a downstream portion thereof to form a mixing zone therewith for receiving liquid-to-be-atomized therein from an unobstructed passage and atomizing fluid directing the liquid-to-be-atomized away from the core. The mixing zone leads to a nozzle orifice outlet. The core is mounted in a core holder and is adjustable by a screw thread, in close proximity to the mixing zone, to adjust the width of the mixing zone. The liquid-to-be-atomized (e.g. a coal slurry fuel) and the atomizing fluid (e.g. air) are fed along coaxial tubes which are slidably mounted by glands to accommodate differential expansions.

摘要： A wear resistant atomizing nozzle assembly is provided having an outwardly diverging, frustum of a cone-shaped deflector core of wear resistant ceramic and a nozzle rim of wear resistant ceramic and having an outwardly flared inner surface encircling the core to form a flared, atomizing nozzle orifice therewith. The core is mounted in a flared socket of a deflector core holder and inner and outer sleeves feed, say, atomizing air to the deflector core surface and, say, a coal liquid mixture fuel inwardly around the nozzle rim so that the fuel is held by the air as a film against the nozzle rim inner surface and then atomized as it emerges from the nozzle rim.

摘要： An aqueous phase continuous, fuel slurry is claimed, and its method of production from agglomerates consisting essentially of carbonaceous particles, agglomerating oil and residual water. The slurry may be formed by thoroughly mixing with agglomerates an agglomerate dispersing and coal/oil/water system interfacial tension reducing agent with the agglomerates so that the agglomerates are broken down and an aqueous phase continuous fuel slurry is formed containing residual, oil produced flocs from the agglomerates and having an oil content of the fuel slurry no greater than 10 weight % of the solids content of the fuel slurry. The solids content of the fuel slurry is in the range of the order of 50 weight % and of the order of 80 weight % of the total weight of the fuel slurry, and is preferably in the range of the order of 65 weight % to of the order of 70 weight %. Examples of interfacial tension reducing agents are ethanol, methanol, glycol, butyl alcohol, isopropyl alcohol, lauryl sulfonates, alkyl sulfonates, lignosulfonates, sodium oleate, nonyl-phenolethoxylates, and soaps. With fuel slurries according to the invention, there may be very slow sedimentary consolidation of the carbonaceous particles, but when it does occur there is no difficulty in re-mixing the constituents into a slurry because the residual aggregates or flocs cause the carbonaceous particles to pack down to a porous bed.

摘要： An atomizing nozzle primarily designed for agricultural spraying has a narrow and controlled droplet size distribution and the ability to shape the spray into a solid cone or fan for evenly applying the spray to the crops. The nozzle is able to operate at low air delivery pressures, in the order of 10 to 30 in. of water column. A central air delivery bore communicates with an air manifold within a boom. Near the exit plane of the throat there is provided an inlet conduit connected to the liquid to be sprayed, the conduit being at right angles to the bore axis. An outlet nozzle from the conduit is positioned on the bore axis and has its exit plane upstream of the exit plane of the bore so that atomization of the liquid will take place within the central bore between the two exit planes. A pair of shaping nozzles are connected to secondary bores that in turn communicate with the manifold. The shaping nozzles are directed orthogonally to the central bore axis and to the inlet conduit and are located downstream of the exit plane of the central bore. The jets issuing from the shaping nozzles shape the cone-shaped spray into a generally fan-shaped configuration. Because the shaping jets are always at the same pressure as the atomization air the dispersion of the droplets exiting the nozzle will be consistent and the spray pattern will be constant over the operating pressure range of the apparatus.
摘要翻译： 主要设计用于农业喷雾的雾化喷嘴具有窄的和受控的液滴尺寸分布，以及将喷雾成形为固体锥体或风扇以将喷雾均匀地施加到作物的能力。 喷嘴能够在10至30英寸水柱的低空气输送压力下操作。 中央空气输送孔与起重臂内的空气歧管连通。 在喉部的出口平面附近设有连接到待喷射液体的入口导管，导管与孔轴线成直角。 来自导管的出口喷嘴定位在孔轴线上并且其出口平面在孔的出口平面的上游，使得液体的雾化将发生在两个出射平面之间的中心孔内。 一对成型喷嘴连接到次级孔，继而与歧管连通。 成形喷嘴与中心孔轴线和入口管道正交地定向并且位于中心孔的出口平面的下游。 从成形喷嘴发出的喷嘴将锥形喷雾形成为通常扇形的构造。 由于成型射流总是处于与雾化空气相同的压力下，离开喷嘴的液滴的分散体将是一致的，并且喷射模式将在装置的操作压力范围内保持恒定。

摘要： Apparatus for dispersing particulate material in a liquid, for example, particulate coal and agglomerating oil in water, comprising an upwardly extending, cylindrical container for the flow of the coal, oil and water upwardly therethrough passed a lower, flat blade type turbine rotor, an intermediate knife blade type turbine rotor and an upper pitched blade type turbine rotor. An annular shaped portion is around the intermediate rotor and houses the intermediate rotor in a cylindrical duct, longitudinally extending baffles extend upwardly along the container inner surface and are spaced therefrom. The lower rotor causes radially outward flow of the coal-water-oil mixture, the intermediate rotor causes fine break down and homogenization of the coal-water-oil mixture, while the pitched blade type turbine rotor causes reverse flow of the homogenized coal-water-oil mixture producing seed agglomerates of carbonaceous coal particles and oil leaving any ash particles dispersed in the water.

摘要： The invention relates to a nozzle (10) for mixing a gaseous fluid such as air and a liquid such as water and for ejecting an atomized mist of liquid droplets. The nozzle includes a nozzle body defining first (60), second (44) and third (52) annular passages along the length thereof. Pressurized fluid is introduced into the first annular passage (60) and a first restricted annular orifice (68) leads from the first annular passage (60) to the third annular passage (52). Liquid is introduced into the second annular passage (44) and a second restricted annular orifice (48) leads from the second annular passage (44) to the third annular passage (52). Liquid and gaseous fluid are aggressively mixed in the third annular passage (52). A third restricted annular orifice (72) leads from the third annular passage (52) to atmosphere such that mixed liquid and gaseous fluid are forcibly ejected from the nozzle through the third restricted annular orifice (72), the liquid being atomized in small controlled droplets in the ejected gaseous fluid.
