Flame detector - Wikipedia

The intense ionization within the body of a flame can be measured by means by the phenomena of flame rectification whereby an AC current flows more easily in one direction when a voltage is applied. This current can be used to verify flame presence and quality. Such detectors can be used in large industrial process gas heaters and are connected to the flame control system. They usually act as both flame quality monitors and for flame failure detection. They are also commo… WebDec 14, 2002 · Flame detectors Depending on the location of the candle (remote or reachable), and how long it will be unattended for...
