Title:
METHOD AND SYSTEM FOR HEAT RECOVERY IN A THROUGHDRYING TISSUE MAKING PROCESS
Document Type and Number:
WIPO Patent Application WO2005068712
Kind Code:
A3
Abstract:
A throughdrying process and system for the manufacture of a tissue web conveys a fibrous web of cellulose fibers through a throughair drying station that includes one or more throughair dryers. The throughair drying station is supplied with a heated drying medium from a source. After drying the web, the drying medium is conducted away from the throughair drying station as moisture laden exhaust air that is collected, dried, and at least partially recirculated back to the throughair drying station as a supplement to the source of heated drying medium, thereby reducing the load on the heated drying medium source.
