UV Type Visible Light Infrared Hybrid Flam Scanner, Gas Oil Flame Detection High Performance Ignition System Device
XHT Flame detection device of power station boiler of large combustion equipment of furnace safety supervisory system and a variety of industrial furnace,the key equipment of burner flame detection.The device according to the physical properties of the combustion flame detection,When the flame burning state does not meet the normal condition or flameout,it will show signal by some mode (Switch quantity and analog quantity),as logic judgment of the fault alarm or furnace safety supervisory system(FSSS).
Technical advantages:
1. Using the latest software and hardware identification technology, with high reliability.
2. With a self-test function, and has higher safety.
3. Adapt to all types of fuel, including gas, fuel, coal and other fuel types.
Detection mode, including ion type, light type and image type.
Applications:
NHT Flame detection device is widely used in electric power,Iron
and steel, metallurgy, petrochemical and other industries a variety
of boiler,burner flame detection, and also can be applied to
various occasions the need for flame detection.
Specifications:
Sr. | Name | Model | Description |
1 | Falme scanner | XHT-1 | Contact type flame detector |
2 | Falme scanner | XHT-2 | Micro flame ionization detector |
3 | Falme scanner | XHT-3 | UV type, gas and oil flame detection |
4 | Falme scanner | XHT-4 | Infrared type |
5 | Falme scanner | XHT-5 | Visible light, infrared hybrid, detection of oil, coal and rich in visible light of the gas flame; Also applies to low nitrogen oxide NOx burn |
XHT-3 UV type flame detector
1) basic configuration:
Flame detector 1pcs ,probe 1pcs, Processor and between the probe with two core twisted pair shielding cable
2) Performance parameters:
Working principle:Flame light signal send to the end of the probe
UV photosensitive tube, UV photosensitive tube complete the
photoelectric conversion,In order to improve the anti jamming
ability to adopt current transmission mode from probe to
detector , then send to the detector by two core cable,The
electrical signal show fire on , fire off by switch ouput
after processing by detector .
NHT-3 probe two kinds of installation:
NHT-31 Endoscope type , the probe through the conduit is
mounted on the interior of the furnace
NHT-32 Outside peep type, probe mounted in the external of
the furnace
