Know if a pilot flame is lit with confidence
Reuter-Stokes Flame Sensors
Reuter-Stokes is well known for flame sensors in gas turbines in the power industry. The UV based Flame Tracker is standard OEM equipment on many models. The Flame Tracker Dry FTD325 is an evolution of that model to help ISPs and end users reduce maintenance costs and remove the risk of damage from complex water-cooling systems by ensuring temperature sensitive components are not subjected to the extreme temperature the sensor end is exposed to.
The UV base flame scanners are able to respond faster to changes in flame status because it is not subjected to black body radiation like IR sensors are and does not have the inertial memory of a thermocouple. Because it is relied on for proper operation of critical infrastructure like gas turbines, the Flame Tracker family is ideally suited where other service prone technologies, like thermocouples, tend to fail. Top fired steam methane reformers tend to use flame sensors for start up only, and expect them to fail at some point before operations are ramped down. The excessive heat where the sensors are installed tend to burn out these traditional sensors. The Flame Tracker will continue to operate throughout the plant lifecycle and not be replaced because it has be designed to withstand temperatures beyond the range of required for reformers.

GE's Flame Tracker sensor, based on Silicon Carbide (SiC) technology, improves gas turbine performance while significantly reducing maintenance requirements. The Flame Tracker's high sensitivity to longer UV wavelengths enables it to have a wide dynamic range and fast response time, minimizing false flameouts and improving turbine reliability.
- Provides reliable operation
- Eliminates signal flicker
- Allows full operation during the water wash cycle
- Reduces maintenance time
- Operates on low voltage
- Provides rapid response to flameout
- Produces a wide dynamic range
- Delivers 10 times the sensitivity of tube-style sensors
Our Reuter-Stokes Flame Tracker Dry 325 senses the ultraviolet (UV) wavelengths produced by a flame and signals whether a flame condition exists. This rugged design reduces maintenance by moving sensitive electronics away from the heat, thereby eliminating the need for water cooling. The Silicon Carbide (SiC) optical photodiode is designed for use with multiple fuels, low NOx combustors and steam injection.
The Flame Tracker Dry 325 can replace any Reuter-Stokes Flame Tracker where end user wants to eliminate the use of water cooling.
The Flame Tracker Dry FTD325 is ideally suited for steam methane reformers, especially top fired systems that produce excessive heat near instrumentation causing a high failure rate.. In the instrument house on top of reformer can reach 150 deg C whereas the FTD325 was design to handle temperatures up to 310 deg C. This ensures operators are never left without critical information about the flame within the reformer. This reduces risk of adding methane or syngas to the process when no flame is present, critical a potential explosion risk.
Flame Tracker EGF is designed for use with enclosed ground flares where traditional thermocouples can fail to provide reliable, accurate information due to the slow response of the system and higher failure rate. The line of site measurement with a UV sensor provides near instant reading of flare pilot status ensure operators know immediately should a pilot go out.
