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
