Boiler Burners

Dynaswirl-LN™ Burner

The Dynaswirl-LN™ low-NOx utility boiler burner offers high-efficiency, low-emission combustion for industrial boilers and is capable of simultaneous gas and oil firing, offering reliable performance and compliance with stringent environmental standards.

Overview

Improve Boiler Performance, Reduce NOx Emissions

Our Dynaswirl-LN™ low-NOx utility boiler burner is designed to improve boiler performance while significantly reducing NOx emissions. Engineered for heat inputs ranging from 30 to 300 MMBtu/hr (8.8 to 88 MW) per burner, the Dynaswirl-LN™ burner supports simultaneous gas and oil firing.


With advanced CFD modeling, the burner ensures equal distribution of combustion air and flue gas recirculation (FGR), resulting in efficient and stable combustion. It achieves up to a 50% NOx reduction over conventional burners and up to a 90% reduction when combined with FGR or over-fire air (OFA). Its capability to operate with stack O2 levels as low as 0.5% and high turndown ratios (8:1 on oil and up to 20:1 on gas) makes it a versatile solution for various industrial applications.

Features

  • NOx Reduction: Achieves up to a 50% NOx reduction over conventional burners and up to a 90% NOx reduction with FGR or OFA.
  • Low Stack O2 Levels: Operable with stack O2 levels of 0.5% or less.
  • Stable Combustion: Minimizes boiler vibration and ensures reliable flame stability with FGR rates as high as 45%.
  • High Turndown Ratios: Offers ratios of 8:1 on oil and up to 20:1 on gas.
  • Low Emissions: Reduces NOx, CO, VOC, and particulate matter (PM) emissions.
  • Hydrogen-Ready: Optimized to fire hydrogen and other alternative fuels, supporting future energy transitions.
  • Gas/Oil Firing: Capable of firing both fuels simultaneously.
  • No Moving Parts: Ensures reliable service with low maintenance.
  • Air Sleeve Damper: Allows for taking burners out of service efficiently.
  • Optional Removable Gas Injectors: Enhances flexibility and maintenance.

Benefits

  • Environmental Compliance: Meets stringent emissions regulations, reducing NOx and particulate emissions.
  • Operational Flexibility: Wide operating range and adjustable flame shaping for diverse industrial applications.
  • Cost Efficiency: Lowers operating and maintenance costs due to its robust and reliable design.
  • Enhanced Performance: Efficient combustion with low excess air operation and low-pressure drop.
  • Ease of Use: Simple installation and combustion controls for user-friendly operation.
  • Reliable Operation: No moving parts during normal operation ensure consistent performance.
