Integrated Condensing Steam Boiler with FGR Flue Gas Recirculation Technology
The Steam Boiler is a key component in modern industrial and commercial heating systems, providing reliable and efficient steam generation for various applications. Our Integrated Condensing Steam Boiler adopts advanced FGR (Flue Gas Recirculation) combustion technology, which recirculates a portion of the flue gas mixed with air back into the combustion chamber. This approach effectively reduces the temperature and oxygen concentration in the combustion zone. Since the activation energy for the reaction between fuel and oxygen is much lower than that between oxygen and nitrogen, fuel primarily reacts with oxygen, and only excess oxygen reacts with nitrogen. The lower temperature in the reaction zone significantly slows down the nitrogen reaction, effectively suppressing thermal NOx formation.
Through extensive research and testing at Foster Wheeler's R&D Center, the boiler structure has been optimized and matched with fully international brand low-NOx burners. Combined with our independently developed PLC control system, this ensures the Steam Boiler operates in a highly environmentally friendly, energy-efficient, safe, and reliable manner. Test data demonstrates that after adopting FGR, NOx emission concentrations can be reduced to below 30 mg/Nm³ (O₂ = 3.5%), meeting stringent environmental regulations.
Performance Advantages of Integrated Condensing Steam Boiler
Ultra-low nitrogen emissions: The combination of advanced combustion technology and flue gas recirculation keeps nitrogen oxide (NOx) emissions extremely low, complying with the most stringent environmental standards.
High efficiency and energy savings: The condensing device recovers both the sensible heat in flue gas and the latent heat from water vapor condensation, significantly improving thermal efficiency and reducing energy costs.
Compact and space-saving design: The integrated structure allows a smaller footprint, saving space in the boiler room, and simplifies installation and transportation.
Intelligent PLC control: Equipped with a high-performance PLC and touch screen, the boiler features automated start/stop, combustion power adjustment, water level control, overpressure and overtemperature alarms, and real-time operation monitoring for easy management.
Safe and reliable operation: Multiple safety protections, including high/low water level protection, overpressure protection, and flameout protection, ensure the Steam Boiler operates safely and reliably.
Wide industrial application: Ideal for chemical plants, food processing, pharmaceuticals, textiles, and other industries requiring high-quality steam, ensuring consistent performance and environmental compliance.
Environmentally friendly and sustainable: Reduced NOx emissions, high energy recovery, and optimized combustion contribute to lower environmental impact, supporting sustainable production goals.
Our Integrated Condensing Steam Boiler with FGR technology is a state-of-the-art solution for industrial and commercial steam generation, combining efficiency, safety, and environmental compliance to meet the demands of modern operations.
