The flame monitor consists of a flame sensor and a control unit.
Flame sensor for monitoring the combustion of a gas, liquid, coal type of flame.
It is used in single burner systems.
The sensor element integrated in the sensor will generate an electrical signal, depending on the flame intensity, which is sent to the flame sensor control unit or the burner control unit.
Depending on the fuel used, various sensors are used for the D-LE 103 flame detector.
Flame detector for monitoring the combustion of gas and liquid fuels for use in gas turbines and other types of equipment with especially harsh operating conditions
Combining the high sensitivity of the photocell and the robust design, the D-GT800 / 801 is suitable for use in harsh environments such as gas turbines.
A photodiode detects almost all types of blue flame, for example a gas having a low content of radiating components in the visible spectrum.
The D-GT 800/801 is available with various photocells, which allows you to choose the best sensor for your specific application.
A unit with a self-diagnosis function, fail-safe for controlling optical flame sensors DURAG UV, UV + IR or IR range for monitoring torch burners for liquid, gas and coal fuels for use in multi-burner units.
The D-UG 660 flame sensor control unit processes the signal received from the flame sensor.
Information about the current settings and the status of the flame signal is constantly displayed on the display.
Flame intensity and flame signal can be transmitted via two 0 / 4..20 mA outputs for subsequent analysis.
The automatic control unit for burners operating on gas and liquid fuels, as well as combined burners on liquid / gas fuels of any power with a self-diagnosis function, is fail-safe.
When starting gas and liquid fuel burners, a certain ignition sequence must be required, which is ensured and controlled automatically by the burner control unit.
The D-GF 150 implements several programs that provide the following automatic sequences:
Pneumatic device for automatically moving the ignition peak to the ignition position and its subsequent
withdrawal from the combustion zone.
For reliable ignition using a high energy electric igniter, it is necessary that the electric discharges generated at the end of the ignition peak are in direct contact with the gas-air mixture. But the temperature in the optimum ignition zone during burner operation is usually extremely high and can damage the tip of the ignition peak.
The pneumatic feeding device is designed to move the ignition peak to the ignition position and then return it to the position in which the ignition tip will be outside the hot zone.
