Monitoring of gas, oil and coal flames

July 2011 Sensors & Transducers

Durag’s D-UG 660/D-LE 603 flame monitoring system is ideal for monitoring all kinds of furnaces under difficult conditions. Typical applications are power stations, chemical industries, refineries, cement plants and waste incinerators. The combination of the D-UG 660 control unit and D-LE 603 flame sensors offers detailed information and adjustment options. It is recommended for use in furnace plants with several burners that make demands on selectivity at high sensitivity levels.

To compensate for a fuel change or for strong movements of the flame, a secondary flame sensor connected in parallel can take over flame monitoring. This operating convenience makes the D-UG 660 universally suitable for use in plants of varying fuel types and load conditions.

Due to the potentially high risk of combustion processes, every flame monitor should meet the highest standards for safety. Therefore, the design of the D-UG 660/D-LE 603 is failsafe with the ability to perform periodic self checks. A dual channel microprocessor system ensures safe operation of the flame monitor.

The system offers a selection of adjustment options including flame on threshold, gain and high-pass filter frequency. The flame on indication can be set in 100 steps and extraneous light from adjacent flames does not interfere. Parallel connection between various optical flame sensors, UV/UV, IR/IR or UV/IR, is possible with only signals corresponding to flame flickering being processed.
