Advanced diagnostic instrumentation for combustion turbines
This paper presents the conclusions derived to date from the diagnostic instruments installed on the gas turbine at Houston Lighting and Power. Optical pyrometry is a practical method of indicating hotter than normal turbine blades, thereby identifying blades whose lifetimes may be substantially shortened. Rapid response measurement of the exhaust temperature shows values roughly 80/sup 0/F higher than that measured with the slower response exhaust thermocouples. Measurement of gas and metal temperatures in the first stage of a turbine appears to have implications for turbine control. That is, using inferred temperatures based on exhaust gas sensors leads to a sizable safety margin. Controlling to more exact measurements of turbine inlet temperatures would allow higher peak power to be generated from a given turbine unit.
