Flame Tracker

Designed for peak performance
and reliability

The Silicon Carbide (SiC) Flame Tracker dramatically improves gas turbine performance while significantly reducing maintenance requirements. Available for a variety of gas turbines, the Flame Tracker flame sensor’s optical photodiode is designed for use with multiple fuels, low nitrogen oxide (NOx) combustors and steam injection. Reliable turbine operations using dry low NOx combustion require the sensitivity provided by the Flame Trackers.

Advantages

High sensitivity, fast response

Flame Tracker, with its SiC photodiode, has high sensitivity to the longer UV wavelengths that easily penetrate the fog of fuel and steam. This is advantageous over typical flame sensors that are sensitive to only the short UV wavelengths. In addition, the SiC sensor has an analog output with a very wide dynamic range and rapid response time. These features offer the ability to quickly—in less than 0.025 seconds—report flame status. This means interruption-free service and improved availability.

Reduced maintenance

The Flame Tracker flame sensor is equipped with quick disconnect connectors, allowing sensor replacement time to be reduced from hours to minutes. Its improved sensor-cooling feature lowers the impact of surrounding heat and extends the life of electronics.

Customized conversion kits

Customized flame sensor conversion kits are available for all turbine configurations. These sensor enhancements are mechanically and electrically interchangeable with existing systems. The kit solution simplifies upgrading older, maintenance-intensive systems to the superior performance of the Flame Tracker.

Multiple applications

Designed to replace outdated technology, the Flame Tracker is applicable to a variety of land-based and marine-based gas turbines, regardless of size. In addition, it is ETL, ATEX, and
IECEx certified.

Reliable, low-voltage operation

Providing a 4–20 mA industry-standard output signal, the Flame Tracker operates reliably with any fuel—with or without— steam injection. Unlike older flame sensors that require high voltage for operation, the Flame Tracker requires low voltage, which eliminates special wiring and explosion-proof conduit requirements.
