<p>Rotary drying drum for high-speed drying of thin webs such as paper or the like comprising a hollow cylinder mounted for rotation and adapted to receive a condensable fluid and discharge condensate. Improved heat transfer is obtained by spoiler bars positioned around the inner drum circumference generally parallel to the drum axis. The invention includes dividing these bars into segments and attaching each segment; a single fixture may be used for each segment and end contact with adjacent bar segments prevents the segments from rotational movement around the fixture point. As a result, performance is improved due to the ability of the bar segments to expand and flex with the drum's surface without excessive stress on the attaching fixtures.</p> |
