Steam & Condensate System Improvements

On high-speed machines, dryer bars are normally used to break up the rimming laminar condensate layer and thus improve heat transfer. For a given diameter dryer, the speeds at which the above stages occur depend on the amount of condensate in the dryer. As the quantity of condensate in a dryer decreases, rimming will take place at a slower speed.
