摘要
Substantially uniform heat transfer through the cylindrical heat transfer wall of a steam heated hollow dryer drum is attained by longitudinal spoiler bars effecting turbulence of condensate throughout a major extent of the inner surface of the heat transfer wall, and condensate turbulence is generated in a narrow annular area from which a stationary siphon intake head withdraws the condensate from the steam chamber. A turbulence promoter is carried by the intake head and may comprise rigid or yieldably supported structure, e.g. a brush, rigid or flexible bar structure, an array of fingers, mounted on the downstream or off-running side of the intake head having regard to the direction of rotation of the drum.
