Burner controls :
The supervision circuit initiates the required safety actions not only in the case of premature or missing flame signals, but also in the event of any kind of fault on the flame detector, the detector cables or the flame signal amplifier that could simulate a flame signal during burner operation.
The burner controls are therefore suited for use in all types of oil- or gas-fired combustion plant where self-checking flame supervision systems are either mandatory or recommended.
For example:
Flame supervision when using LGK16... - Flame detector QRA53.../QRA55...
- Ionization probe
- Flame detector QRA53.../QRA55... together with ionization probe, e.g. in the case of burners using a pilot burner (also see Data Sheet N7712)
- For gas, oil or dual-fuel forced draft burners of medium to high capacity
- With self-checking flame signal amplifier
- For continuously operating multistage or modulating oil or gas burners of medium to high capacity
- With air pressure supervision for checked air damper control.
- Burner control for oil burners to EN 230: 2005
The supervision circuit initiates the required safety actions not only in the case of premature or missing flame signals, but also in the event of any kind of fault on the flame detector, the detector cables or the flame signal amplifier that could simulate a flame signal during burner operation.
The burner controls are therefore suited for use in all types of oil- or gas-fired combustion plant where self-checking flame supervision systems are either mandatory or recommended.
For example:
- Burners that operate continuously
- Burners in intermittent operation that, in the case of great heat demand, may operate continuously for more than 14 hours, e.g. in plant using boiler sequencing
- Burners that need to comply with the German TRD 411 and TRD 412 regulations for steam boilers
- Burners in plant where, for specific safety requirements, supervision of the burner by a self-checking flame supervision system seems advisable
-
The control sequence and connection circuitry of the LOK16…/LGK16… burner controls are identical to those of the LAL2... and LFL1... respectively (with the exception of the LFL1.148), so that existing combustion plant can also be equipped with self-checking burner controls,
- provided very good flame detector current values are measured in the plant supervised so far by the LFL1..., and
- provided the following types of flame detectors are either installed or can subsequently be fitted:
Flame supervision when using LGK16... - Flame detector QRA53.../QRA55...
- Ionization probe
- Flame detector QRA53.../QRA55... together with ionization probe, e.g. in the case of burners using a pilot burner (also see Data Sheet N7712)
