    摘要： Apparatus is described for rapidly coating a large area, or for rapidly producing a powder. In one embodiment, a liquid having a coating chemical is pumped from a liquid reservoir to a distribution manifold. From the distribution manifold, the liquid is carried under pressure to a geometric array, e.g., linear, of atomization nozzles. Flow equalization means are provided for equalizing the flow of the liquid delivered to each nozzle, and, preferably, means are provided for equalizing the temperature of the liquid delivered to each nozzle. The liquid, upon exiting the nozzles with the attendant pressure drop atomizes. The atomized liquid coats a substrate either in non-reacted or reacted form, or forms a powder. In a preferred embodiment, a solution of precursor chemical is reacted in a geometric array of flames produced at the nozzles, and a coating material produced in the flame coats the substrate, or a powder is formed. In another embodiment, vaporized precursor and vaporized are fed to a burner chamber having a linear exit slit. The vapor exiting the slit is burned, and material produced in a flame reaction are deposited on a substrate, or the powder formed is collected.

    摘要： The present invention involves controlled atomization of liquids for various applications such as part/droplet seeding for laser-based measurements of flow velocity, temperature, and concentration; flame and a plasma based elemental analysis; nano-powder production; spray drying for generation of small-sized particles; nebulizers in the production of sub-micron size droplets and for atomizing fuel for use in combustion chambers. In these and other atomizer applications the control of droplet and/or particle size is very critical In some applications extremely small droplets are preferred (less than a micron), while in others, droplet diameters on the scale of several microns are required. The present invention has the flexibility of forming droplets within a particular range of diameters, wherein not only the size of the average droplet can be adjusted, but the range of sizes may be adjusted as well. The atomizer (4) itself is in the form of a heated tube (44) having an inlet end (48) and an outlet end (50). As liquid travels through the tube it is heated and upon exiting the tube and entering a reduced pressure area the liquid atomizes to form very fine droplets. By electrically heating the tube by passing a current therethrough, the heating adjustment can be performed on-the-fly allowing size adjustment during operation of the atomizer. Several different embodiments of the atomization device are disclosed.
