How does a fireye work?
The Fireye flame safeguard checks for a short-circuited, or “runaway” scanner at the beginning and end of each flame cycle. The scanner is UL listed and FM approved. The UV tube is made of quartz and is filled with a gas that ionizes when struck by UV radiation from the flame.
What is flame scanner in boiler?
The flame detector detects if the pilot light or main flame is actually lit. When properly installed and serviced, flame detectors are designed to prevent boiler explosions caused by the ignition of fuel accumulated within the burner chamber during a flame failure.
What is UV scanner?
What is a UV Scanner? A UV Scanner is just one piece in the larger scale of a burner management system (BMS). The UV Scanner detects the ultraviolet radiation emitted by combustion flames. The flame supervision is designed to detect or not to detect a flame.
What causes flame failure on boilers?
Delayed ignition can be caused by a range of problems, including a restricted or weak pilot light. Also, low gas supply pressure can mean that there is too little gas at the burners, resulting in ignition problems. Another possible cause is too much primary air. This is air that’s mixed with gas before it’s ignited.
How do IR flame detectors work?
Infrared flame detectors – These sensors operate by using an infrared band. A small thermal imaging camera in these detectors can instantly detect the presence of hot gasses released anywhere near the infrared detector. Infrared waves can penetrate dust, smoke, fuel particles and oil films.
What does a fire eye scanner control?
Fireye Flame Scanners provide a variety of UV and IR flame scanners that accurately detect the presence or absence of flame in a combustion chamber and some provide both self-check and non-self check capabilities.
What is flame eye sensor?
Fireye provides a variety of UV and IR flame scanners which accurately detect the presence or absence of flame in a combustion chamber. Our scanners include advanced sensors and algorithms that can discriminate its target burner from adjacent flames in the same combustion chamber.
What is boiler flame failure?
There are different ways to perform the boiler flame failure test. The flame failure trip in a typical boiler can be due to one of the following reasons: loss of ignition; fuel valve closed, unstable flame, low airflow, very high furnace pressure, dirty flame sensor and loss of electrical supply.
How do you test UV sensor?
Always refer to the owner’s manual for your specific UV system.
- Enable the “Test mode” function in the operator menu.
- Unscrew the union nut from the measuring glass.
- Pull the UV sensor out.
- Insert reference sensor and check displayed value.
- Put the unit’s UV sensor back in.
- Screw the union nut into place.
What is UV flame detector?
UV flame detectors are sensory devices that are designed to respond to Ultraviolet radiation that has a wavelength that is less than 300nm. The sensor in the device is a photo-tube that includes a cathode and an anode placed in a large P of about 300 volts and sealed in a tube filled with inert gas.
