<p>An apparatus is provided for use in monitoring for destructive wet compression power augmentation-related casing distortions in an industrial gas turbine equipped with and employing wet compression power augmentation, comprising: an outer ring member (417) having an inner diameter which exceeds the outer diameter of a gas turbine section downstream of the compressor; three or more members (421) spaced substantially equally over the ring member's inner circumference and which extend inwardly along respective radii of the ring member but define a central opening not intersected by any of the three members and which also is larger in diameter than the gas turbine section, the three members together defining a common plane, said common plane being parallel to a plane including the outer ring member over its circumference and the center of mass of said outer ring member, and wherein one of the three inwardly-extending members is equipped at its inner end with a socket or ball (425, 427) element of a ball and socket joint; and a laser reflector (405) positioned on the outer ring member (417).</p> |
