This is Part 2 of a discussion on Gas Turbine Operation with my guest, Robert Hawkins. In Part 1 we covered concepts related to the basic operation of Gas Turbines, which are important to understand for effective troubleshooting when issues arise. In Part 2 we cover issues that can occur with startup, shutdown, and combustion. In Part 3 we will cover considerations related to support systems, compressor performance and water wash, turbine performance, and vibration monitoring.
