Boiler Burners

QLN® Low NOx Burners

John Zink’s QLN® burner delivers low NOx emissions for once-through steam generators (OTSGs) and heaters while maintaining high efficiency and reliability, with advanced fuel staging and internal flue gas recirculation (FGR).

Overview

Advanced Air/Fuel Premixing and Fuel Staging

Our QLN® burners are engineered for superior performance in once-through steam generators (OTSGs) and heaters. These burners use advanced air/fuel premixing and fuel staging techniques to significantly reduce NOx emissions. This burner's design offers a diffuse flame that creates an ideal heat flux environment for process heaters, while providing a single burner heat input range not offered by traditional process burners.

Designed for maximum efficiency and reliability, the QLN® burners can handle a firing capacity of up to 450 MMBTU/HR HHV. These burners are suitable for both gas and #2/light oil firing, providing flexibility and high performance across various fuel types. Their compact and innovative design ensures ease of installation and maintenance, making them ideal for both new installations and retrofit applications.
