ABSTRACT:
A steam heated dryer of the hollow rotary drum type employed to dry paper webs of indefinite length. The steam condensate (water) is continuously removed from the lower interior portion of the drum by a siphon-like tube, the horizontal part of the condensate removal tube is stationary with respect to the rotating drum and its separate, angled input end spaced from the drum interior wall. The input end executes limited angular motion, so as to follow the mass of the condensate which rises slightly up the sides of the drum upon drum rotation. A bellows expansion joint is carried by the condensate removal tube. The condensate removal tube is supported by one or more spider supports, the spider supports formed of a heat resistant elastomer or resin, the spider support carrying a self-lubricating bearing ring which receives the condensate tube. Damage due to vibration is reduced. The pressure differential between the steam entering the drying drum and that in the condensate return tube is such that the condensate return tube is always filled with condensate, thus inhibiting flashing of the liquid condensate in the tube back into steam. Non-condensable gases are removed from the drum interior by an eductor effect produced in a portion of the condensate return line.
