A bit more than a bearing fire I believe............
On Tuesday 4th February at 6:00 am Ironbridge Power Station, Unit 1 suffered a failure of 12 blades at the row 6 position on Low Pressure (LP) Turbine No. 2 causing a fire. There was some secondary fire damage, but no injuries. Emergency services were called to site to assist in the extinguishing of the fire.
Investigation of the incident has progressed and has firmly identified that the LP2 row 6 blade 66 failed as a result of high cycle fatigue initiated from an area of water droplet erosion located on the trailing edge of the aerofoil approximately 20mm above the root of the blade. At the time of the failure the LP Turbine was at full speed with no load.
Further information related to the failure will be communicated on conclusion of the incident investigation.
