Raadman Low NOx and Ultra Low NOx Burners deliver reliable, high-efficiency combustion while significantly reducing nitrogen oxide (NOx) emissions. Designed for industrial and large-scale heating applications, they optimize fuel-air mixing, control flame temperatures, and, in some models, use Flue Gas Recirculation (FGR) to further cut emissions. With stable, uniform flames, these burners ensure consistent performance and long-term reliability. Suitable for industries from metal and chemical processing to food, pharmaceuticals, and large heating systems. Raadman burners combine efficiency with environmental compliance, helping you achieve both performance and sustainability goals.
Low NOx burners are engineered to deliver cleaner combustion and higher efficiency, making them a top solution for industrial and thermal systems. By optimizing the fuel-air mixing through using a specially designed combustion head, these burners significantly reduce nitrogen oxide (NOx) emissions while maintaining high combustion efficiency and reliable performance.
Low NOx burners minimize NOx emissions by enhancing mixing and controlling peak flame temperature. Their advanced combustion head ensures that air and fuel mix gradually and evenly, preventing hot zones in the flame core. This creates a uniform flame with lower peak temperatures, directly reducing NOx formation.
Some models also feature Flue Gas Recirculation (FGR) system. In these systems, Recirculated gases act as diluents, lowering flame temperature and limiting active oxygen, which further reduces thermal NOx formation.
Low NOx burners are crucial for modern industries, delivering optimized thermal performance while keeping NOx emissions minimal. This combination of efficiency and environmental compliance makes them essential across various applications:
Metal & Steel Industry
supports high-temperature processes with low emissions.
Petrochemical & Chemical Industries
ensures safe, continuous operation with strict emission controls.
Food & Pharmaceutical Industries
clean combustion with high hygiene and process stability.
Large-Scale Heating Systems
Reliable heat production with maximum efficiency and minimal impact
Raadman Low NOx Burners provide exceptional versatility, covering a firing range from 350 kW up to 6 MW. With advanced combustion heads, optimized fuel-air mixing, and optional FGR, they deliver stable, efficient flames with minimal NOx emissions.
Modulating models include integrated control systems for precise operation under varying loads. Built in compliance with international standards, Raadman Low NOx Burners ensure safe, efficient, and environmentally responsible performance, providing long-term reliability and flexibility for diverse projects.
Ultra Low NOx burners are designed for industries that need extremely low emissions without sacrificing performance. Compared to standard Low NOx burners, they cut NOx levels even further while still delivering stable flames and high efficiency.
These burners are a perfect choice for applications where strict environmental rules and reliable operation are both critical.
Ultra Low NOx technology works by carefully controlling how fuel and air mix and burn. With advanced premixed combustion and high-quality metal fiber burner heads, the flame spreads evenly and burns at lower peak temperatures. Since high flame temperature is the main cause of NOx formation, reducing it leads to much cleaner combustion. The result is ultra-low emissions with the same safety, stability, and efficiency expected from modern industrial burners.
Ultra Low NOx burners are designed for industries where strict emission limits and high-performance combustion are critical:
Food & Pharmaceutical Processing
reliable, hygienic combustion with consistent thermal performance.
Condensing Boilers
When used with condensing boilers they create a very efficient and clean heating system for HVAC applications
Raadman Ultra Low NOx burners are available in Premixed and Post-mixed designs, providing flexible solutions for a wide range of industrial applications.
Premixed models (150 kW–4 MW) mix air and fuel completely through the fan, with the burner body and motor specially engineered to support this process. This ensures uniform flames, high combustion efficiency, and reliable operation across varying loads.
Post-mixed models (500 kW–4 MW) feature Raadman’s patented Post mixed technology, in which air and fuel are mixed after the fan. This design delivers the same high performance and stable combustion as Premixed models, without requiring specialized burner body or motor engineering.
In both Premixed and Post-mixed designs, air and fuel are fully homogenized before reaching the metal fiber combustion head, ensuring safe ignition, stable flame, and highly efficient combustion, which is essential for reducing NOx emissions. These burners are fully compliant with international standards, including BS-EN 676, guaranteeing safety, reliability, and environmental responsibility across industrial applications.
