Energy Efficiency of Steam Showers TAPPI Papermakers Conference April 2006

摘要

Steam showers heating the sheet during the forming and pressing process can remove more steam from the dryer than they are supplied with but the primary financial payback comes from improved sheet properties, machine runnability and dryer limited production increases. This paper documents dryer load reductions achieved by heating the sheet or press fabric on machines making pulp, linerboard and fine paper along with economic justifications of using steam showers. It discusses the most efficient locations to install a steam shower for various grades and machine configurations as well as recommended operating techniques. It also offers suggestions on how to optimize performance of a steam shower, evaluate benefits and justify the costs of installing and operating one.
