BFI Automation Compact Flame Controller
For the flame radiation analysis, a well approved integral procedure in the respective spectrum is carried out with the compact flame controller. After a pre-amplification, the unwanted continuous wave light component is withdrawn from the output signal of the wear-resistant detector. The subsequent sensitiveness attitude allows an attenuation of the signal for adaptation to the combustion process. The post-connected band pass filter caused, that only the typical modulation of the flame radiation of the primary combustion zone is valued and so extraneous light signals by neighboring burners can be distinguished from its own flame. Further functional groups include signal conditioning the dynamic monitoring channel which checks the fail safe function of the device continuously.
A component or component defect leads to an immediate disconnection of the flame relay, which output is available as a floating change-over contact for use with the burner management system. The switching condition is announced additionally by a yellow LED on the reverse side of the device behind the Perspex pane. For the optimal adjustment of the compact flame controller the flame strength can be read off directly on the device by means of a pulsating green LED. For the visualization or remote indication, a current output is available at 0 or 4-20 mA. The safety switch-off time which depends on the combustibles to be checked is set ex-works to a second. Longer switch-off times are available upon request.
BFI's compact flame controllers come in different models each offering slightly different features but the same technical specifications.

BFI Automation System 3000 Flame Scanner 7.x
In combination with a flame amplifier module of the 3000 or 4000 line the flame scanner 7.0 and 7.1 forms a complete flame monitoring system for meeting the safety requirements for steam generators. The flame monitoring system 3000/4000 is tested and approved in accordance with EN298:2012.
The method developed by and patented by BFI Automation to detect a flame by sensing the temperature re-circulation of its combustion gases, opens up completely new applications for safeguarding a firing plant. Monitoring for controlling fuels previously possible only by employing expensive parallel operation of UV and IR flame scanners, can now be replaced simply and offering a substantial increase of availability by our Flame Scanner 7.0 and Flame Scanner 7.1. Faulty opening due to absorption of flame radiation, caused by fuel composition or charging of additional media no longer occurs. Faulty light signals due to combustion chamber radiation are ruled out. The choice of the spectral range specifies the lowest flame temperature from which detection takes place.
The solution for monitoring combustion processes of any kind is based on sensing and evaluating the difference of flame temperature and variation of the same at two predetermined points.
The patented method is making use of the fact that combustion is maintained only when there is always sufficient energy fed back into the ignition zone in order to maintain combustion.
As radiation sensors, two thermoelement chains are used. These have linear sensitivity across the complete radiation emitted by the flames and therefore can be made selective for defined wave length ranges using filters. An optical system defines the two cones of view and pre-allocates the wave length range temporarily. Additional filters can further reduce the flame spectrum to be evaluated so we are able to pick up only the spectral lines of typical combustion products (for instance, CO, CO2 , H2 S or H2O). This way, application oriented flame evaluation can be done.
BFI Automation Flame Scanner 7.0
The flame scanner 7.0 can be used where combustion processes must be monitored in which flame radiation does not occur as continuous radiation bands or where reliable detection in the IR range is not possible due to reflection from the combustion chamber (hot brick lining, red-hot melt). Main places of application are combustion chambers, rotary kilns, melting furnaces and grate firing installations.
In plants that do sulphur reclamation (Claus process), only H2S combustion is monitored and the combustion chamber usually is full of steam. The addition of backup gas, required by the other optical flame monitoring systems can be done away with. Measurements using thermocouples that are costly and subject to heavy wear can now be replaced with the flame scanner 7.0 to increase the availability of the process.
BFI Automation Flame Scanner 7.1
The flame scanner 7.1 can be used where combustion processes must be monitored in which flame radiation does not occur as continuous radiation bands or where reliable detection in the IR range is not possible due to reflection from the combustion chamber (hot brick lining, red-hot melt). Main places of application are plants for thermal treatment and energy recovery, pesticides, contaminated waste gas, tail gas, furnace gas, tar oil, and pitch. Beyond that also conventional gas, oil, and coal dust firing plants are equipped with the flame scanner 7.1 when availability of the plant is a top objective.
BFI Automation System 3000 Flame Scanner 4.x
In connection with a flame amplifier of the 3000 or 4000 line, the flame scanner 4.1, 4.2 or 4.3 forms a complete flame monitoring system and meets the safety requirements for steam generators. The flame monitoring system 3000/4000 is tested and approved acc. to EN298:2012.
Flame Scanner 4.0
The basis for the use of light and heavy fuel is the consequential utilization of the fuels own high frequency flame modulation even under extreme low NOx conditions. The possibility to vary the size of the flame monitoring field by means of the 3-step aperture, a reliable monitoring of boxer and tangential firings is offered, even if the sight tube is not in an optimized position. This flame scanner therefore finds it main application in large steam generators and industrial firings of any type.
A silicon photo element senses the electromagnetic radiation released during the combustion process from near ultraviolet to near infrared. The evaluation of the flame modulation resulting from the fuel oxidation with oxygen permits a clear and separate identification of the typical flame signals from liquid fuels against coal firing signals. A precise shielding of the flicker frequencies smaller 60Hz achieves the suppression of background radiation due to adjacent burners or combustion chamber walls. The remaining information is then sufficient to provide a precise flame evaluation. Further functional groups serve for the processing and forming of signals into standardized digital signals which are transmitted to the flame scanner. This fully electronic flame scanner has no moveable mechanical parts. The photo element is non-ageing thus achieving that the sensitivity of the monitoring equipment remains unaffected even after years of service, maintenance is not necessary. This means that the user has a significantly enhanced usage of his entire firing equipment.
BFI Automation Flame Scanner 4.1
An automatic amplification adjustment with adaption to the dust-typical flame modulation under low-NOx conditions is the basic requirement for the use of high volatile and heavy-ballast hard and brown coal. The oil ignition flame is controlled simultaneously, thus increasing the availability during the critical transition phases which in general occur during startup and shut-down of mills. By choosing the optical size of the flame monitoring field by means of a 3-step aperture, a reliable monitoring is achieved, also at boxer and tangential firings, and even if the sight tube is not in the optimal position.
The radiation sensed by a photo element is immediately processed by a control circuit (AGC) optimizing the operating point of the flame scanner in slave-operation with the fuel radiation. Then a precise suppression of the flicker frequencies smaller 40Hz, achieves the suppression of background radiation caused by adjacent burners or combustion chambers. An additional automatic frequency control (AFC) avoids unsteady signals, caused by either changing dust quality or by changing ignition zone on the burner load range. The further possibilities to choose 3 different flame modulation characteristics, and the size determination of the sight field, permits the application of this flame scanner in all combustion chamber geometries and burner constructions. The following functional groups serve for the signal processing of the flame evaluation and conversion into standardized digital signals transmitted to the flame monitoring unit. This fully electronic flame scanner has no moveable mechanical parts. The photo element is non-ageing, thus achieving that the sensitivity of the monitoring equipment remains unaffected even after years of service, maintenance is not necessary. This means that the user has a significantly enhanced usage of the entire firing equipment.
BFI Automation Flame Scanner 4.2
The automatic amplification control with adaption to the flame modulation of gas-oil and coal flames permits an application completely independent from fuel. The free choice of size of the flame monitoring field of the combustion and the specific layout of the modulation filter makes the flame scanner 4.2 a reliable monitoring device for fluidized-bed – and grid firings as well as for wood flames.
The radiation sensed by a photo element is immediately processed by a control circuit (AGC) optimizing the operating point of the flame scanner in slave-operation with the fuel radiation. Then a precise suppression of the flicker frequencies smaller 25Hz, achieves the suppression of background radiation caused by adjacent burners or combustion chambers. An additional automatic frequency control (AFC) avoids unsteady signals, caused by either changing dust quality or by changing ignition zone on the burner load range. The further possibilities to choose 3 different flame modulation characteristics, and the size determination of the sight field, permits the application of this flame scanner in all combustion chamber geometries and burner constructions. The following functional groups serve for the signal processing of the flame evaluation and conversion into standardized digital signals transmitted to the flame monitoring unit. This fully electronic flame scanner has no moveable mechanical parts. The photo element is non-ageing, thus achieving that the sensitivity of the monitoring equipment remains unaffected even after years of service, maintenance is not necessary. This means that the user has a significantly enhanced usage of the entire firing equipment.
BFI Automation System 3000 Flame Scanner 3.x
In connection with a flame detector of the 3000 or 4000 line, the flame scanner 3.31 and 3.32 forms a complete flame monitoring system and meets the safety requirements for steam generators. The flame monitoring system 3000/4000 is tested and approved in accordance to EN298:2012. The main application for this fully electronic UVflame scanner is the gas and oil flame detection for the selective burner monitoring in high power combustion chambers. The possibility to safely apply an extraordinary wide range of gaseous and liquid fuels, even when adding absorbing means such as flue gas or water vapour, serves as basis for the application in low-NOx conditions. This evidences, that this scanner is most suited for the use in large steam generators and in industrial firings with complicated individual flame detection or with very different flame radiation. Increased availability demand also leads to an increased use in one-burner installations of any size.
The flame scanner 3.31 utilizes a new concept of the UV-flame radiation analysis. A photo element senses the modulated UV-radiation released during the fuel pyrolysis. The intensity of flame depends on the concentration and modulation of the chemo-luminance radiation of the free radicals (OH, CN, CH, C2). This procedure bases on the chemical combustion process thus achieving a flame detection and selective burner monitoring which was not possible before. It furthermore supplies valuable information for the flame evaluation. This technology bases on the application of a wide-band UV-semi-conductor element, which enables the evaluation of modulated UVradiation, in difference to the usual small band tubes which are subject to wear. To achieve a precision tuning of discrimination and flame evaluation, a sensitivity tuning enables the attenuation of the flame signal for the adaption to the specific fuel radiation. The variable modulation filter has the effect, that the typical high frequent flame radiation of the primary combustion zone is evaluated only. Further function modes transfer rated digital signals to the flame amplifier.
BFI Automation System 3000 Flame Scanner 2.0
SIL3 CERTIFIED IN COMBINATION WITH FLAME AMPLIFIER 3001(D)(S)
The flame scanner 2.0 is based on the spectral the UV-VIS and IR flame radiation analysis. Both spectral regions by a dual detector recorded separately and selectively with an automatic Vorverstärkerregelung and integrated frequency control evaluated.
In connection with a flame detector of the 3000 or 4000 line, the flame scanner 2.0 forms a complete flame monitoring system and meets the safety requirements for steam generators. The flame monitoring system 3000/4000 is tested and approved in accordance to EN 298:2012. The application range for this fully electronic UVVIS-IR flame scanner is the gas-and oil flame detection for the selective burner monitoring in large steam generators, in single-burner installations, and also for special application purposes as for instance in gas turbines.
The flame scanner system 2.0 is based on the UV-VIS spectral procedure and on the IR flame radiation analysis.
Both spectral ranges are detected separately by a binary detector and evaluated selective by means of an automatic preamplifier circuit and integrated frequency control. This achieves an optimum spectral utilization of the high-frequency flame modulation of the primary combustion zone, thus avoiding suppression of the UV-VIS flicker frequencies, since the high energy IR radiation is processed separately. The generally undesired diffused light of the flame serves for the fuel specific control of the flame scanner. The binary detector consists of a lead sulfide carrier with a vapor deposited silicon photo element.
The SI element serves as an UV filter for the PbS photo element arranged behind it on the same optical axis, and blanks out the detrimental short waves which otherwise would cause problems with the PbS detectors. Due to a compensation controlled by the ambient temperature, the working point of the scanner is stabilized and the spectral linearity is maintained. In a mixed stage the signals of both photo elements result in a bus signal of a very large spectral bandwidth. The spectral shift of the flame provides information about oxidation of the fuel thus offering information about the flame quality.
The signals of the UV-VIS and IR radiation intensity can be adjusted separately to achieve full evaluation of the flame. The on-load connected band pass has the effect that the typical modulation of flame radiation of the primary combustion zone is utilized for the output signal only. The further functional groups achieve the conversion into digital information acc. to standard with highest fail-safe features. By means of the BFI special cable KW5 it is possible to realize a length of up to 500 m without having to use a further driver unit between flame scanner and amplifier.

This flame scanner is equipped with multiple-semi-conductor sensors and covers the spectral range from UV to IR. Separate sensitivity adjustment for UV and IR range. Automatic Gain and Frequency Control (AGC & AFC)
BFI Automation Flame Scanner Type 2.0 LA-EX
The flame scanner 2.0 LA-EX is designed detect flames on Gas Turbines in ATEX Zone 1 with fibre optic solution and provides flame information to a BFI flame amplifier. This flame scanner is equipped with multiple-semi-conductor sensors and covers the spectral range from UV to IR. Separate sensitivity adjustment for UV and IR range. Automatic Gain and Frequency Control (AGC & AFC).
BFI Automation System 3000 Flame Amplifier Module 3001
The flame amplifier 3001 contains two separate signal processing channels of differing layout, which are being synchronised by a processor. Internal and external faults of any kind trigger automatically immediate actuation of the safety devices. Two independent monitoring levels (time level I, time level II) can freely be selected by means of an external control signal. Each level is described by its sensitivity setting and sign-off time. In this way a fuel- and load-related optimisation of flame monitoring is easy to implement. The connection of a second flame detector in parallel or alternating operation is possible. The output signal of the flame detector is transmitted as a pulse message via a filter and pulse shape stage to the sensitive controllers. Two rotary switches are available per time level for setting the desired signal amplification. This flame signal is distributed on three further function channels:
-
Measuring channel (M)
-
Monitoring channel (RM)
-
Evaluation channel (RF)
