Hydrogen Flame Detector – D-GT 800

DURAG GROUP

Flame sensor for monitoring gas and oil flames in gas turbines or harsh environments
Self-monitoring and fail-safe in conjunction with control unit/burner control
Ideal for use in harsh environments like gas turbines
Optionally available with air/water cooling
Compliant with general safety regulations

The D-GT 800 DURAG is a flame sensor designed for monitoring gas and oil flames, primarily in gas turbines or in particularly harsh environments. It features a highly sensitive photo element and a sturdy design, making it ideal for use in harsh environments such as gas turbines. The sensor can detect almost all blue burning flames, including gas flames with a low radiation component in the visible range. It is available with different photo elements for optimal selectivity when using different fuels. The D-GT 800 is ATEX-approved and compliant with general safety regulations, ensuring safe operation in demanding conditions. It can be deployed with high combustion chamber overpressure and strong vibrations, and it is compatible with control units such as the D-UG 120, D-UG 660, and D-GF 150. It is also optionally available with air or water cooling for use in very high-temperature environments.

Use Cases

Burners with difficult installation conditions for conventional flame sensors or on those where ambient temperature near the sighting tube is very high
Power stations
Chemical industry
Refineries
Cement plants
Waste incinerators
Steam generators
Heating plants
Gas turbines
Hydrogen burner monitoring (100% H2 or H2-mix fuels)

Capabilities

Flame monitoring in the UV-range from 190 to 570 nm
Deployable with high combustion chamber overpressure and with strong vibrations
Compliant to general safety regulations
Self-monitoring and fail-safe in conjunction with a control unit/ burner control
Connection to the D-UG 120, D-UG 660 control units and the D-GF 150 (-MB) burner control
Optionally available with air/water cooling
Flame monitoring in the UV-range from 190 to 570 nm
ATEX-approved (D-GT 800/801../Ex)

DURAG GROUP DURAG GROUP, a German gas analysis and measurement technology company, supports hydrogen purity monitoring through its subsidiary AP2E's ProCeas gas analyzers, which have been developing hydrogen industry solutions since 2015 and participated in the EU-funded MetroHyVe research project for controlling hydrogen purity per ISO 14687:2019. The ProCeas gas analyzer, based on patented OFCEAS (Optical Feedback Cavity Enhanced Absorption Spectroscopy) technology combined with low-pressure sampling (LPS), monitors trace-level impurities such as CO, HCHO, NH3, H2S, COS, and H2O at hydrogen refueling stations, providing real-time contaminant detection compliant with ISO 14687, EN 17124, ISO 19880, and Northern Lights CCUS specifications with no drift and no recalibration required. SGS France's laboratory in Harfleur uses ProCeas devices to monitor hydrogen purity for mobility applications (grade D, 99.97% purity), quantifying 14 different impurities from ppb to ppm levels in a single sample injection. DURAG GROUP also provides H2-ready combustion control and safety solutions including customized burners, igniters, flame scanners supporting up to 100% hydrogen fuel mixtures, and video/thermography monitoring systems for safe, reliable operation with complex and variable fuel mixtures.
