My Turbine Has Run For Years... Why Did it Fail Now?
Steam turbines exist in most every major industrial facility. Many of these turbines have been running for years and have been very stable. Typically, after a period of time, the equipment is shut down for maintenance during a planned outage. It is more common than not that the turbine will experience problems after the shutdown and perhaps even failure or high vibration will occur. On the surface, this does not make any sense, because the turbine ran fine for years and now, right after the shut- down, there are problems in bringing the machine up.
KnightHawk has observed these problems over the years.
