    May 09, 2017 Dryer Camera Brings Condensate Behavior to Light. As the old saying goes, “Seeing is believing.”. So goes proving to people how condensate behaves in a steam-heated rotating cylinder (e.g., a roll or a dryer). Trying to describe what is going on inside a rotating cylinder can be difficult. Add in trying to describe the heat transfer process that is being influenced by the condensate behavior

    What is claimed is 1. In a rotary dryer having a shell adapted to receive steam under pressure into the hollow interior thereof for heating the shell to dry material passed over the outer surface thereof, resulting in the formation of condensate which rims the inner surface of the shell, and an exhaust manifold mounted within the shell and extending substantially the length of the shell and

    Aug 17, 2012 up with the rotating dryer shell, and a thin film of condensate forms around the shell surface. Stage 3 - Cascading. Faster rotation of the dryer causes the puddle to move farther up the shell until gravity forces overcome centrifugal forces and the condensate showers back into the bottom of the dryer. Stage 4 - Rimming. As the dryer rotation speed is increased further, centrifugal forces overcome

  • Papermaking PAPERMACHINE – DRYING Introduction Papermaking PAPERMACHINE – DRYING Introduction

    In the rimming regime, condensate is held on the dryer surface by centrifugal forces. Nevertheless, there is a relative velocity between the condensate and cylinder, as given by equation (2) in Figure 8. This is called “sloshing”. This is important in attaining convective heat transfer through the condensate, thereby increasing the heat transfer
