Advanced NOx Reduction and OFA Technology

Ammegen is a pioneer in providing cost-effective NOx emissions solutions across a wide range of combustion processes. Our advanced over-fire-air (OFA) and selective non-catalytic reduction systems are the core of our NOx emissions reduction portfolio.

These systems are custom engineered to your unique application and can be applied individually or in combination with a range of integrated systems to ensure compliance with your specific and evolving needs. Our systems are customised to fit each client’s unique system properties and plant configuration. CFD combustion modelling is a vital element in our design evaluation and optimisation, used to support the development of your tailored solution.

Our Approach to OFA

  • In conjunction with burner replacement or upgrades
  • OFA and/or advanced boosted or hybrid OFA depending on NOx reduction requirements
  • Customised design to fit specific furnace configuration
  • CFD combustion modelling to locate the OFA nozzles
  • Maximising NOx reduction whilst maintaining or improving combustion performance
