Abstract: An apparatus and method to use steam to atomize water to produce a mixture of moisture and heat for application to the web of a paper machine for both production improvement and paper quality control. The method allows independent droplet size and heat control in the mixture, resulting in flexibility that can not be offered by conventional steam showers or water spray systems individually. In one embodiment the apparatus consists of a plurality of actuator nozzle modules which control the water volume flow feeding the nozzle through a pneumatic pressure signal. Pressurized steam feeding the nozzle is used to break the water into fine droplets. The resulting nozzle spray is a mixture of moisture in fine water droplets and steam vapor, and heat stored in the steam. Alternatively, a plurality of steam valves can be used to regulate the steam volume flow feeding each atomizing nozzle.

Abstract: This invention relates to a three-stream atomizing nozzle for use with a rewet shower. The nozzle has an air stream divider that separates the atomizing air from the source into three streams. The first stream is a straight air stream staying closest to and around the atomized water jet. The second stream is a swirl running around the first straight stream. The third stream is also a straight stream that wraps around the first straight stream and the second swirl. The nozzle also has a mixing chamber in which the three air streams are mixed together for the atomizing purpose. The nozzle can from the combination of the three air streams produce fine water droplets that are suitable for a paper rewet shower and more importantly creates a tailorable water mass profile. The mass profile can be tailored into a shape that is close to a square shape which is ideal for rewet showers as a square profile creates minimal coupling between adjacent zones.

Abstract translation: 本发明涉及一种与再润湿淋浴一起使用的三流雾化喷嘴。 喷嘴具有将雾化空气与源分离成三个流的气流分配器。 第一条流是保持最靠近雾化水射流的直线空气流。 第二条流是围绕第一条直线流动的漩涡。 第三条流也是围绕第一直流和第二涡流的直流。 喷嘴还具有混合室，其中三个气流混合在一起用于雾化目的。 喷嘴可以从三个气流的组合产生适合于纸再润湿淋浴的精细水滴，并且更重要地产生可裁剪的水质量分布。 质量轮廓可以被定制成接近于正方形的形状，这对于再湿淋浴是理想的，因为方形轮廓在相邻区域之间创建最小的耦合。
