Burner controls type LOK16.../LGK16... feature a self-checking flame supervision
circuit.
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:
Silicon photocell detector RAR9...
-
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)
