Flame Ionization Sensor Testing in a Pressurized Combustor

摘要

The National Energy Technology Laboratory (NETL) and Woodward Industrial Controls are developing a Combustion Control and Diagnostics Sensor (CCADS), an ionization-based sensor for monitoring hydrocarbon combustion in turbines. The patented CCADS design offers a unique multi-function sensor capability. This unique capability coupled with a durable and simple design has increased commercial interest in CCADS for gas turbine applications. A commercial prototype CCADS has been developed and tested under a Cooperative Research and Development Agreement (CRADA) between NETL and Woodward. Tests in an industrial-scale high pressure combustor demonstrated detection of flashback, combustion dynamics monitoring, and detection of lean blowout precursors. With real-time monitoring of the combustion process that CCADS can provide, turbine controls are envisioned which would allow sustained low-emissions performance.
