Flame Detectors

Flame Detectors | UV Cells | Photocells

Photocells and flame detectors are designed to detect the safe operation of the burner. When the photocell is coupled with a suitable flame controller they produce a signal to allow the burner to continue to run in the presence of a flame, or to shut it down safely in the absence of a flame.

Photocells or flame detectors are generally only used where a ‘fail safe’ needs to be installed for commercial and industrial boilers.

The photocell or flame detectors job is to allow the flow of current and to convert AC current to DC current when it detects the presence of a flame.

Flame Detectors

New Solid State UV Detectors

Larger more expensive flame monitoring systems used in Power stations and on large turbines have relied for a long time on solid state flame detection. These systems often integrate clever electronics allowing them to be tuned to a specific type of flame, but the cost has always been too high to allow the tech to be transferred to main stream industries, UNTIL NOW! BST Solutions have designed and manufactured a range of flame detectors for all types of burner, all environments and with the technology from the larger systems made by their sister company BFI Automation. These small incredibly powerful flame detectors are fully interchangeable with any UV or IR type cell. All BST products are individually CE marked and are certified for use with ANY control box. This allows you to swap out any device and replace it with a BST Detector and keep the certification of the burner completely legal.

This new BST range is becoming increasingly popular with OEM's here in the UK and already has a large presence in Europe. Power Heating pLants are proud to be the official BST Solutions distributors for the UK and Europe. If you would like any further information about the products and their capabilities or technical specifications, please contact us.

UV Sensors

UV sensors have a tube that responds to ultraviolet radiation, this radiation emitted by the flame is then picked up by the UV sensor and tells the flame controller that there is a flame present and to carry on operating.

There are a few drawbacks to UV sensors though, one is that the UV sensors sometimes pick up radiation from non-flame related UV sources such as cosmic, gamma, and x-ray radiation. Despite this, countermeasures can be taken to ensure that there is always a correct reading of the flames presence or absence, these include:

  • The UV sensors view of the first third of the flame must be unobstructed.
  • The sensor should not sight the ignition spark.
  • The UV sensor cannot be subjected to excessively high temperatures.

Infrared Sensors

Infrared sensors can be used with either gas or oil flames, this is due to the characteristics of the flame, more than 90% of the flames radiation is infrared. This results in the infrared flame detectors being able to operate with a very high-intensity flame or a very weak one.

For the flame detector to work though, the sensor must have a good view of the flame, the infrared sensor must be protected from any direct flames, and the flame detector leads must be wired correctly according to standard procedure.
