ABSTRACT:
The rotor exhaust gas bulk total temperature relative to the last blade row of a combustion turbine is determined by traversing an optical pyrometer radially across the last stage blades. The resulting radial temperature measurements are then flow weight averaged to provide an accurate bulk gas temperature relative to the last row of blades. Such temperature is useful in a feedback control system for the turbine. A technique of traversing is to cause the optical pyrometer to traverse by mounting its line of sight or optical axis at an angle to its axis of rotation.
