Abstract
A steam distributor that uses a porous metal plate to replace the conventional screen plate of a steam shower for distributing steam to a moving web such as the web of a paper making machine. Steam showers using a steam distributor with this porous metal plate can deliver extremely uniform steam to the surface of a paper web. Profiling steam showers constructed by using an array of the steam distributors are able to deliver the best profiling results for various paper products. The porous metal plate can be considered as an equivalent of a screen plate with thousands of micro-orifices arranged tightly in both the machine direction and the CD direction.
