Durag’s burner control system

April 2014 Analytical Instrumentation & Environmental Monitoring

The Durag D-GF 150 burner control system controls and monitors gas and oil burners of any capacity. The control functions include prepurge, ignition and solenoid valve control, through to the enabling of the output regulation. The flexible program sequence for pre-purge, ignition, fuel supply and air supply may be adjusted to the requirements of the plant. These units may be used in applications ranging from large power stations to small remote heating plants, as well as in chemical processes or thermal flue gas combustion systems.

By employing microprocessors with corresponding software and hardware, this burner management system offers improved evaluation capability and a heightened degree of safety and availability. In combination with flame sensors from either the D-LE 103 or D-LE 603 series, the burner management system is fully suited to monitor flames of different fuels and combustion techniques, in single burner or multi-burner systems. Different UV and IR flame sensors are available to adapt the flame monitoring system optimally to local conditions. The response threshold (sensitivity) of the flame monitoring system in the burner control may be set to one of 10 different levels using a rocker switch on the front panel of the burner control.

The types of fuels and burners found in the field require different functional sequences and safety times, which are electronically controlled and monitored by the burner control system. By observing the applicable guidelines, it is possible to choose from the following program sequences, depending on the current operating conditions of the combustion system: fuel gas in master burner mode, fuel gas in slave burner mode, fuel oil in master burner mode and fuel oil in slave burner mode.

Beside these standard functions the D-GF 150 burner control features an integrated gas valve proving system, separate outputs for controlling gas and oil fuel valves, quick fuel change on the fly, without burner shut-down, data interface and program halt for burner optimisation.

Keeping an eye on invisible radiation
Omniflex Remote Monitoring Specialists Analytical Instrumentation & Environmental Monitoring
At its peak in 1994, the energy generation capacity of the UK’s nuclear power stations was 12,7 GW across 16 plants. In 2024, the capacity has fallen to around 5 GW, and the number of stations is down to nine. However, this is far from the end of the story as spent nuclear fuel remains radioactive for centuries, and requires rigorous safety processes to safeguard against leaks.
