摘要： A feedstock injector for connection to a source of heated gas comprises a converging channel extending from the upstream end to the downstream end of the injector. A splitting arm extends diagonally within the converging channel, the splitting arm comprising two symmetrically opposed surfaces extending from the inlet to the outlet ends of the converging channel. A feedstock injection passage opens axially at the downstream end of the splitting arm. The gas stream discharged by the injector contacts and entrains the feedstock with improved uniformity.

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： A gas nozzle for a dryer apparatus for use with moving webs includes a planar pressure plate with an upstream end portion and a downstream terminus portion and a gas discharge nozzle disposed at the upstream portion of the pressure plate to define a slot for gas flow parallel to the pressure plate. The nozzle includes a first jet forming plate which engages the upstream end portion of the pressure plate and at obtuse angle and which includes a vortex forming step. The nozzle also includes a second jet forming plate located a distance from the first jet forming plate. The two jet forming plates and the step define a passageway for gas flow parallel to the pressure plate.

摘要： Nozzle apparatus for airborne paper web dryers of the non-impingement or underpressure type including a blow box member defined by top web supporting and bottom wall portions and back and front wall portions. The front and top supporting wall portions are interconnected by a curved guide surface and an upwardly directed nozzle is provided on the front wall portion spaced below the entry edge plane of the guide surface. The relative values of the width of the nozzle gap and the radius of curvature of the curved guide surface are such that the gas flow exiting from the nozzle follows a portion of the guide surface and departs therefrom prior to the exit edge plane of the guide surface. The upper surface of the top supporting wall of the blow box defines a small angle with the running plane of the web.

摘要： The burner comprises inner and outer tubular concentrically arranged conduits having their outlets positioned approximately in the same plane. The inner conduit is connected to a high pressure gas source; the outer conduit is connected to a low pressure gas source. The end face of the inner conduit forms a valve seat in which a Coanda-type valve body seats. The valve body is axially displaceable away from the valve seat so as to co-operate therewith to form an annular passage. A tubular shroud concentrically surrounds the conduit outlets and valve body in spaced relation therewith. In operation, high pressure gas unseats the valve body and flows at high velocity through the annular passage. This gas flow follows the surface of the valve body in the form of an attached jet and creates a low pressure zone adjacent said valve body surface, with the result that low pressure gas is sucked or drawn out of the outer conduit and simultaneously air is drafted into the annulus formed between the shroud and the valve body. The three streams mix in the annulus to form a combustible mixture. The burner is advantageous in that it provides improved suction and mixing, thereby using a relatively low amount of high pressure gas in its operation.
摘要翻译：该燃烧器包括内管和外管同心布置的管道，其出口大致位于同一平面内。内管连接高压气源; 外部管道连接到低压气体源。内管道的端面形成一个阀座，其中柯安达式阀体位于该阀座中。阀体可以远离阀座轴向移动，以便与其配合以形成环形通道。管状护罩同心地围绕导管出口和阀体与其间隔开的关系。在操作中，高压气体使阀体脱离并通过环形通道高速流动。这种气流以附接射流的形式跟随阀体的表面，并且产生邻近所述阀体表面的低压区，结果是低压气体被吸入或从外导管抽出并同时空气被吸入进入形成在护罩和阀体之间的环形空间中。三个流在环形空间中混合形成可燃混合物。燃烧器的优点在于其提供改进的吸入和混合，从而在其操作中使用相对低量的高压气体。
