dampfbeheizter trockenzylinder a paper machine with a device for increasing the transfer of heat energy from the inside wall of the cylinder to the light

摘要

An apparatus (10) is disclosed for increasing a transfer of thermal energy through an inner surface (12) of a hollow cylindrical dryer (14) of a papermaking machine to a peripheral outer surface (16) of the dryer. The apparatus includes a plurality of bars (18-35) of rectangular cross-sectional configuration, each of the bars extending axially within the dryer. The bars are disposed spaced and parallel relative to each other with each of the bars being urged outwardly against the inner surface of the dryer. Also, each of the bars defines an axially extending enclosure (38). IMAGE
