Use of Steam Showers to Condition Press Fabrics, 2003 Spring Technical Conference Proceedings
Since 1969 more than fifty non-turbulent steam injector showers have been installed over uhle boxes to heat press fabrics. A hot fabric runs drier, cleaner and more open. Mill personnel using steam showers to heat their fabrics report that steam application makes it easier to remove contaminants, particularly waxes from the system thereby reducing cleaning chemical usage and in some cases eliminating the need to batch wash. Dryer limited production increases of more than 1% or equivalent steam savings have been
documented by heating one or more press fabrics with a steam shower over the uhle box. This paper
discusses the effect that steam application has on fabric temperature, moisture and porosity as well as its effect on dryer steam reduction and increased machine speed. It also outlines which fabrics and paper grades benefit the most from steam application.
