9.2 Flame Monitoring
9.2.1 Integral Flame Monitoring (Option)
9.2.1.1 Purpose
The integral flame monitoring system is primarily used for standard applications (e.g. oil or gas
flames at a burner in a combustion chamber) because of it’s limited adjustment possibilities.
NOTICE
We recommend the LAMTEC flame monitoring systems (like F300K, F200K2), if you have
other requirements for the flame monitoring (e.g. combustion of coal dust). You will find infor-
mation on this devices in the corresponding manuals (DLT7650, DLT7600 and DLT7502/
DLT7503).
The task of the flame monitoring device is to scan the burner’s flame in combustion plants un-
affected from any condition in the combustion chamber (e.g. glowing nogging) and to release
the closing of the fuel valves at a flame blow out with an internal control command of the burn-
er control system.
The flame monitoring device has the following tasks:
– Scanning the burner flame unaffected of the conditions in the combustion chamber (e.g.
glowing refractory lining)
– internal release of the control command to close the fuel valves at a flame blow out with
the burner control system
Connect the following LAMTEC flame sensors:
FFS08 IR/UV, FFS07 IR/UV (also in version for Ex zone 1 or Ex zone 2).
NOTICE
The F250 flame scanner as well as FFS05 and FFS06 flame sensors are discontinued since
01/2014 and are not taken into account in the current certifications.
Approvals for flame scanner/sensor in conjunction with ETAMATIC with validity from that date
are not valid for F250, FFS05 or FFS06.
Replacement for FFS05 = FFS07
Replacement for FFS06 = FFS08
Replacement for F250 = F152 or F200K (depending on application)
9.2.1.2 Characteristics flame sensor
Input variables - optical flame sensor
Required input values from the flame's emitted radiation indication "Flame present”
– Spectral radiation region = 260......400nm (FFS07 UV-1, FFS08 UV-1)
– Spectral radiation region = 215....360 nm (FFS07 UV-4, FFS08 UV-4, replace UV-2)
– Spectral radiation region = 1200....2800 nm (FFS08 IR-1, FFS07 IR-1, FFS07 IR-1 T,
FFS08 IR-1T, FFS08 IR-1 T/S2)
– Pulse frequency ca. 10...200 Hz
– Pulse amplitude 10mV
