Abstract

<p>“Yankee is a heart of the Tissue machine.” This is a word which shows importance of the Yankee in making the tissue. Yankee decides the production capacity and the sheet quality of moisture profile and crepe. The Yankee is also a 2nd class pressure vessel in Japan law. The performance related to these very important roles of the Yankee greatly depends on the maintenance work for the Yankee. This paper describes some of Andritz Yankee life cycle management service, that is, first we describe the Yankee inspection based on TAPPI. The routine periodic inspections can record the actual Yankee situation and make a database for the scheduled maintenance work. Next we describe the OTR （On The Run） measurement for the Yankee. It measures the Yankee surface profile and temperature profile at Yankee running status. It can provide important information about crowing, next grinding timing, status of condensate discharge and others. Andritz Yankee life cycle management service described here will provide the information for the proper maintenance work of the Yankee.</p>
