Allen, J M

Apparatus is described for measuring rotor exhaust gas bulk total temperature in a combustion turbine which includes first and last stages of rotating turbine blades comprising: optical pyrometer means for measuring the circumferentially total gas averaged temperature relative to said last stage turbine blades at a plurality of common radial points from the turbine hub to tip where said optical pyrometer means includes a single optical pyrometer having a line of sight along with means for rotating such pyrometer around an axis of rotation, with the pyrometer being tilted from said axis so that the line of sight of said pyrometer rotates around said axis thereby providing a radial traverse of said last stage turbine blades; means for calculating said rotor exhaust bulk total temperature relative to said last stage blades by flow weight averaging said measured temperatures of said radial points.
