YANKEE DRYER HAVING CENTRIFUGALLY ASSISTED CONDENSATE COLLECTION

摘要

A Yankee dryer which exploits centrifugal forces to assist in evacuating condensate. A condensate collection system has individual pickup straws arranged at an angle such that the required amount of motive steam pressure is reduced to extract and move the steam condensate from the intake opening of the straw to the discharge point of that straw. The pickup straws communicate with a collection header arranged along the length of the Yankee dryer. The collection header is configured such that it has a radius from the axis of rotation which is greatest near the point at which collected condensate is discharged to a disposal riser conduit which conducts collected condensate to the exterior of the Yankee dryer.
