    摘要： An atomizer spray plate is provided for discharging fuel oil. The spray plate has a cylindrical rear portion and a conical front portion. A frusto-conical whirl chamber extends from the rear portion to the front portion with a decreasing radius. The rear portion includes a number of whirl slots extending radially inward from an outboard region of the rear portion to the whirl chamber to provide the fuel oil with rotational energy. A discharge slot is provided in the front portion of the spray plate for receiving fuel oil from the whirl chamber with rotational energy. The discharge slot includes a cylindrical through-hole with a diameter d, and at least three lobes (slots) equally spaced about the through-hole and oriented in a radial direction, each lobe having a semi-circular cross-section with radius r and extending approximately perpendicular to a central longitudinal axis of the through-hole.

    摘要： A liquid atomizer for, e.g., fuel, comprises a tube having an opening for receiving pressurized liquid flow. The tube has a closed end, a wall, and one or more bores through the wall. A shell having a discharge end with a discharge orifice encircles a portion of length of the tube, including the tube closed end. The shell forms an annular chamber around the tube end and an end chamber between the closed tube end and the shell discharge end. Liquid under pressure entering the tube opening is directed outwardly through the wall bores into the annular chamber, into the end chamber, and out through the discharge orifice for introduction, for example, into a combustor.

    摘要： A liquid atomizer for, e.g., fuel, comprises a tube having an opening for receiving pressurized liquid flow. The tube has a closed end, a wall, and a plurality of bores in the wall. The bores are disposed in consecutive circumferential rows, and are oriented at an acute angle .alpha. with respect to a radius of the tube and at an acute angle .beta. with respect to a longitudinal axis of the said tube. A shell having a discharge end with a discharge orifice encircles a portion of length of the tube, including the closed end of the tube. The shell forms an annular chamber around the tube end and an end chamber between the closed tube end and the shell discharge end. Liquid under pressure entering the tube opening is directed outwardly through the wall bores into the annular chamber, into the end chamber, and out through the discharge orifice for introduction, for example, into a combustor.

A frusto-conical whirl chamber extends from the rear portion to the front portion with a decreasing radius. The rear portion includes a number of whirl slots extending radially inward from an outboard region of the rear portion to the whirl chamber to provide the fuel oil with rotational energy. A discharge slot is provided in the front portion of the atomizer spray plate for receiving the fuel oil from the whirl chamber with the rotational energy. The discharge slot includes a cylindrical through-hole with a diameter d, and a transverse slot having a semi-circular cross-section with radius r. The discharge slot can be easily and economically fabricated with two shaping steps since there is no need to precisely set any particular non-right angle for walls of the discharge slot. Yet, the discharge slot provides a spray pattern with lateral fuel-rich zones separated by a central fuel-lean zone which inhibits the formation of NO.sub.x by reducing the peak combustion flame temperature generated by the spray pattern.

    摘要： A two phase fuel oil atomizer utilizing a secondary media such as high pressure steam or air to assist in the atomization of heavy fuel oil, while reducing NOx and other polluting emissions. The fuel oil atomizer comprises a mixing plate and a sprayer plate which are configured to discharge atomized fuel oil at varying spray angles in order to provide staging of the atomized fuel as it exits the sprayer plate with the surrounding combustion chamber air to provide a fuel/air ratio that is appropriately rich and lean in order to allow lower flame temperatures. NOx generation is accordingly reduced at the lower flame temperatures. With atomized fuel droplet size small enough to enable rapid fuel evaporation and complete combustion, low CO, opacity and particulate generation are achieved with minimum excess oxygen.

    摘要翻译： 使用诸如高压蒸汽或空气的二级介质的两相燃料油雾化器来辅助重质燃料油的雾化，同时减少NOx和其他污染排放。 燃料油雾化器包括混合板和喷雾器板，其被配置为以变化的喷射角度排出雾化的燃料油，以便当其与周围的燃烧室空气离开喷雾器板时提供雾化燃料的分段，以提供燃料/ 空气比适当丰富且较稀，以允许较低的火焰温度。 因此，在较低的火焰温度下，NOx的生成相应地降低。 由于雾化的燃料液滴尺寸足够小以实现快速的燃料蒸发和完全的燃烧，所以用最少的过量氧气可实现低CO，不透明度和颗粒物的产生。

    摘要： Apparatus is provided for collecting samples of fallout, such as power plant stack emissions, from the environment. A collector substrate is adapted to progressively present a fresh collection surface for the collection of fallout from the environment over time. An opening is disposed between the substrate and the environment to allow the fallout to reach the substrate. A cover is provided for the opening. The cover is automatically closed in the presence of rain to protect the substrate from rainwater, and automatically opened after rain terminates to allow the substrate to collect fallout. Mechanical and electrical embodiments are disclosed for the automatic cover.
