Flame Tracker

Flame Tracker

GE's Silicon Carbide™(SiC) flame sensor dramatically 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.

Features

Standard on all new GE gas turbines, Flame Tracker replaces the vintage Geiger-Muller tube flame detector systems common in gas turbines manufactured prior to 1998.

Economic benefits of Flame Tracker flame sensor include:

  • Longer life - 50% longer design life
  • Lower replacement cost for sensors
  • Fewer nuisance trips due to more sensitive and quicker response (sees broader spectrum of UV)
  • Easier/faster/safer service due to low voltage system (24Vdc) and quick disconnect

Applications

Standard Kits

Due to the voltage differences between the Flame Tracker sensor (24vDC) and the GM tube sensor (335vDC), a conversion kit must be installed. Kits are available for all combustion turbines and control systems. A standard kit includes:

  • Flame Tracker flame sensors
  • Quick disconnect cables
  • Cooling coils (where required)
  • Electronic interface module(s)
  • Technical documentation
  • Operation and maintenance manuals

Installation

Most customers are able to install the conversion kit using their own plant technicians, however GE does offer installation services if you would prefer.

To get a quote, or for information on Flame Tracker, contact a GE representative. Be sure to include the following information:

  • Turbine serial number
  • Number of flame sensors currently installed
  • Flame detector type of cooling (ambient air or water)
  • Type of turbine control system (MK I, II, IV, V, VI, etc.)
