CONDITION MONITORING AND DIAGNOSIS IN A SOLID-FUEL GASIFICATION PROCESS

The goal of the project is to define and develop a condition monitorin g and diagnostic system for the solid fuel gasification process and im plement the system in a standard digital automation system. The monito ring system is based on static non-linear models and statistical prope rties of measured signals. The system includes monitoring displays and parameter displays for operating and maintaining the system, Model pa rameters and alarm limits are determined automatically during the proc ess operation. System development and testing work was carried out in a two-year project (93-94) and the participants in the project were pr ocess developer Enviropower Inc., automation system manufacturer Valme nt Automation Inc. and the control engineering laboratory of Tampere U niversity of Technology.
