Flame Scanners Manufacturers

Flame scanners are crucial to the safe operation of a combustion system. Flame Scanners comes in two main varieties that include infrared and ultraviolet. Ultraviolet scanners are more sensitive and quicker to respond. If the flame is out, the fuel flow into the combustion enclosure is stopped and the area is purged before a re-light can be attempted. The detector is a gas filled tube that scintillates in the presence of flame ultraviolet radiation and emits bursts of current, called an avalanche, several hundred times per second as long as the flame continues. Use of infrared scanners is desirable of there is a waste stream, such as sulfur, which absorbs ultraviolet light and makes operation of ultraviolet scanners unreliable.
