BFI Automation has been supplying power stations with flame monitoring systems since 1973. All big name boiler and burner manufacturers inside and outside Germany are now amongst our esteemed customers. Our UV semiconductor sensors have revolutionised safeguarding against extraneous light, a very important aspect for multiple burner systems such as steam generators. Our systems have accompanied the development and use of reduced-emission, low-NOx burners in power stations from the very beginning. The latest generation of flame monitors gives the operating personnel a complete overview of the entire firing equipment thanks to the networking of sensors and graphic display of raw flame signals. An understanding of the interaction between the burner parameters and combustion process helps them control the firing equipment more precisely and detect faults in the flame patterns faster.
