In single-burner and multiple-burner furnaces, the flame detector performs a high-safety monitoring of the burner flames. When the flame switches off, the safe control state "Flame off" is reached.

The flame detector is mainly used in large-scale power plants, thermal power stations and chemical plants as well as for monitoring furnaces which are operated with:

  • Oil
  • Gas
  • Bio-mass
  • Dust coal
  • Chemicals and other waste products
