Flame monitoring systems for power plants

In power plants, fuels such as coal, oil, gas or biomass are burned in large combustion chambers to generate heat. Flame monitoring plays a central role here in order to monitor the combustion processes and minimize the risk of damage. Particularly in multi-burner systems with different fuels, the demands on sensor technology are very high. We use highly developed technologies such as infrared or UV sensors to monitor the intensity and frequency of the flame in real time. Unwanted extraneous light caused by background radiation from other burners is detected and suppressed using software-based evaluation procedures. A graphical representation of the entire firing system is possible via a network. Flame monitoring makes a decisive contribution to preventing dangerous incidents such as explosions, fires or overheating. By detecting flame loss or instability at an early stage, the system can automatically initiate an emergency shutdown to prevent major damage.
