Title:
STEAM SUPPLY AND CONDENSATE REMOVING DEVICE FOR STEAM HEATING ROLL
Document Type and Number:
Japanese Patent JPH11156969
Kind Code:
A
Abstract:

To provide a steam supply and condensate removing device which is of a simple structure but is capable of heating a heating roll uniformly and efficiently.

A heating roll 10 is equipped with a steam and condensate transmission system with a steam supply hole 37, a steam transfer flow path hole 36, a steam supply head 26, a steam tube 16, a condensate return head 27, a condensate transfer flow path hole 41 and a condensate return hole 44, all of these being completely hermetically sealed. This system maintains a roll end wall 18 almost at the same temperature as the temperature of a cylindrical outer wall which is working at a routine rotating speed, and sweeps out a non-condensed gas from a steam flow path. When the heating roll 10 rotates slowly or stops, the system shuts off all the condensate return flow paths excepting one return flow path at the bottom part.
