Active control for gas turbine combustors

A Multiple Inlet Swirler for Gas Turbine Combustors

The central recirculation zone (CRZ) in a swirl stabilized gas turbine combustor has a dominant effect on the fuel air mixing process and flame stability. Most of state of the art swirlers share one disadvantage; the fixed swirl number for the same swirler configuration. Thus, in a mathematical sense, Reynolds number becomes the sole parameter for controlling the flow characteristics inside the...

Advanced Sensor Approaches for Monitoring and Control of Gas Turbine Combustors

This report describes sensing strategies that were developed for monitoring the health and performance of gas turbine combustors. Sensor systems based on these approaches enable control and monitoring systems that improve combustor reliability and operability, achieve optimal performance (e.g., lower NOx emissions) over extended periods of time, reduce maintenance, prevent forced outages, and i...
