Analysis of a failure
- Illinois Power Co., Decatur, IL (United States)
This paper is an in-depth look at the events that led up to a ``total black shutdown`` of a 600 MWe fossil generating unit. This shutdown resulted in severe turbine bearing and journal damage. The most significant fact about this incident was that it was the direct result of four concurrent failures. Had any one failure been prevented, the incident would not occurred. These failures also placed the adjacent unit in peril of a similar fate for several hours. This paper identifies the failures that permitted this incident to occur. The paper also explains the corrective actions that were taken to prevent a reoccurrence of this incident. These actions are of special interest to utilities that are upgrading older units with distributed process control including burner management systems.
