Monitoring of UV and IR flames

November 2002 Analytical Instrumentation & Environmental Monitoring

Durag's D-UG 660 control unit, used in conjunction with the D-LE 603/103 flame sensors are ideal for monitoring UV and IR flames, even under difficult operating conditions. After start-up the control unit performs a self test that is repeated during operation, offering improved possibilities of flame signal evaluation and a higher grade of safety and availability.

For interference-free transmission through extensive cable lengths, the flame sensors convert the flame signal into pulses that are used for evaluating the flame's intensity. The 'flame on' message can be set in 100 steps, and extraneous light from adjacent flames will not interfere. Parallel connection between two optical flame sensors, either UV/UV, IR/IR or UV/IR is possible.

Only signals corresponding to flame flickering are processed. Flame monitoring is not influenced by ambient light, and flames where UV radiation is absorbed by dust, water vapour or other materials may be monitored in the infrared range.

IR flame sensors with a sensitivity of up to 1800 nm have been operating successfully in monitoring gas and oil combustion systems employing NOX reduction techniques such as flue gas recirculation.
