Siemens Landis LGK16.335A27 Control Box C21294S
The burner controls are therefore suited for use in all types of oil- or gas-fired combustion plants where self-checking flame supervision systems are either mandatory or recommendable:
- 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 plants using boiler sequencing
- Burners that need to comply with the German TRD 411 and TRD 412 regulations for steam boilers
- Burners in plants where, for specific safety requirements, supervision of the burner by a self-checking flame supervision system seems advisable
- The control sequence and the connection circuitry of the LOK16… / LGK16… burner controls are identical to those of the LAL2... and LFL1... respectively (with the exception of type LFL1.148), so that existing combustion plants can also be equipped with self-checking burner controls, ƒ 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:
Specific features when using LOK16...
- Selenium photocell detector RAR...
Specific features when using LGK16...
- Flame detector QRA53... / QRA55...
- Ionization probe
- Flame detector QRA53... / QRA55... together with ionization probe, e.g. in the case of burners with pilot burner
