BAKER HUGHES SENSOR RS-FS-9001

On Liquid Dry Low Nox Applications, as well as those applications with significant levels of water and steam injection, the ultra-violet light sensed by the Geiger Mueller tube based flame detectors is absorbed by the fog of fuel, steam or water.

GE’s research center invented a silicon carbide (SiC) photodiode that is significantly more sensitive to the longer wavelength components of the UV light generated by the flame. This longer wavelength light does penetrate the fog of oil quite well and therefore the SiC based sensor is significantly more sensitive to the presence of flame.

A flame sensor utilizing the SiC photodiode is being produced by GE Reuter Stokes, and has been successfully operated on a number of GE gas turbine installations.
