Windboxes and OverFire Air Systems (OFA)

• Optimised distribution of combustion air in windboxes to reduce NO_x emissions, improve efficiency and limit the occurrence of operational problems in boilers and furnaces.
• Implementation of OFA (OverFire Air) systems for NO_x reduction::
  • Optimised design for a proper air distribution into the furnace section.
  • Customised solutions for any boiler design
  • Installation of OFA with fan support or BOFA (Boosted OverFire Air) systems

• Implementation of curtain air to protect walls against corrosion phenomena promoted under low NO_x conditions
• Minimisation of imbalances in combustion air supplies to improve combustion efficiency and limit operational constraints
• Redesign of windbox and combustion air registers to improve fan operation costs by reducing pressure drop in the combustion circuit
• Increase of furnace or boiler operation flexibility by the implementation and/or automation of burner regulation capabilities, on a burner-per-burner basis or in groups of burners
• Customised solutions with optimised benefit-cost ratios
• Possible combination with other INERCO combustion optimisation technologies such as como ABACO or FLEXICOM-LNB
