PROBLEM TO BE SOLVED: To provide a method for using thermal imaging equipment to take infrared images of a steam turbine during start-up. SOLUTION: The exterior temperatures developed from the infrared images are correlated with turbine vibration data to determine which insulation temperature patterns reflect insulation poor enough to cause packing seal teeth to rub and the turbine to vibrate during operation or shut-down. From the thermal images and vibration data, control limits are developed for insulation surface temperature. Insulation is added, before the steam turbine is shut down, in accordance with the obtained data and control limits. COPYRIGHT: (C)2004,JPO&NCIPI
