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.
