Gas Turbine Exhaust Gas Measurement The Problem: Liquid Natural Gas requires a lot of power for gas compression. At this site 27 GE Frame 5 gas turbines, manufactured by Nuovo Pignone are used for this process. The original equipment exhaust gas sensors on these turbines are not robust enough to survive the long base load run times which causes turbine trips due to sensor failures. The Challenge: Develop a new exhaust gas sensor that has the following design criteria Must have a longer performance life. Must have flexibility to be installed with a lube oil drain pipe in the way. Must be easily and quickly replaceable when service is required. The Solution: A new sensors design approach was taken to meet the above challenges. The sensor was designed with a slightly larger tip diameter (2m
