DURAG’s Universally Applicable Flame Supervisor for Critical Thermal Processes
The new Flame Supervisor of the DURAG Group is a next-generation optical flame scanner that redefines ease of use, safety, and flexibility in flame monitoring across all fuel types and industrial burner configurations. Engineered for universal deployment in thermal processes, the Flame Supervisor introduces an innovative blend of advanced features, intuitive control, and robust safety compliance—including SIL 3 certification. Whether in industrial furnaces, cement kilns, gas turbines, or waste incineration plants, this compact, versatile device is tailored for the most demanding industrial combustion systems.
“The Flame Supervisor has been developed for all industries that rely on thermal energy which involves the use of a flame as part of its production process. As a comprehensive solution for modern combustion systems, with smart tools that simplify commissioning, it ensures compliance, and delivers operational confidence in various applications,” says Thomas Pniok, Product Manager at DURAG Group. “It delivers robust detection with a wide range of flame characteristics, it supports safer, cleaner operation.”
This includes systems where energy is used to generate steam, hot water, hot air, but also to transform product states, for example solid to liquid or gas, as well as in thermal decomposition processes like steam cracking in the petrochemical industry. It is suited for processes using alternative fuels like biomass, RDF, or SRF, but also for co-firing and WtE systems.
Flexible variants and powerful features for maximum safety and system availability
The Flame Supervisor is available in two variants: for manual rotary switch setup (D-LX 1100) and for advanced, app-supported configuration with multiple filter options (D-LX 2xx0). The fibre optics option (D-LX 27×0) enables reliable flame detection in high-temperature, high-vibration, or difficult-to-access burner areas.
“The intelligent 2-channel architecture is a decisive advantage for a maximum safety and system availability. In the event of an internal fault on one channel, the process continues safely on the second, intact channel – for up to 22 hours and 50 minutes. This gives you the time you need for a controlled shutdown and prevents expensive, abrupt plant shutdowns,” explains Thomas Pniok. “Because the Flame Supervisor is designed for extended temperature ranges, there is no need for external insulation or climate conditioning, ensuring reliability in harsh environments.”
Apart from universal compatibility, versatility, maximum safety, further highlights of the Flame Supervisor are the ease of setup and operation. “Operators of all skill levels can configure the system in minutes with just two buttons, using the auto-learn function for fast and accurate commissioning,” says the Product Manager at DURAG Group. Last but not least, the device comes with its ‘Flame Companion App’ software for Android and Windows, allowing USB, Modbus and wireless configuration via Bluetooth and fine-tuning of settings for specific process needs. Four pre-configured operating modes simplify adaptation to different firing scenarios or fuel types, streamlining the configuration process.
These features make the Flame Supervisor compatible with a wide range of burners, regardless of the manufacturer. From power plant boilers to industrial furnaces, cement kilns, reformers, and waste-to-energy plants, the device ensures reliable flame presence detection in extreme or variable combustion systems. It is also suitable for low-capacity combustion systems where ionization-based flame monitoring is not feasible due to challenging conditions or system design. Whether in the production of cement and building materials, energy production, metal and steel production, food and beverage processing, petrochemical, refinery, and chemical plants, this solution maximizes safety, optimizes efficiency, and secures reliable combustion across a wide range of demanding applications.
