Boiler Burners

Divided Flow (DFL™) Low-Emission Burner

The DFL™ Low-Emission Burner offers efficient and low-emission combustion solutions for industrial boilers with low excess air operation, adjustable flame shaping, and fuel flexibility.

Overview

Superior Combustion with Significantly Reduced Emissions

Our DFL™ Low-Emission Burner is engineered to provide superior combustion performance with significantly reduced emissions. Designed for industrial boiler applications, this advanced burner optimizes system efficiency while maintaining compliance with stringent environmental regulations. It is capable of achieving up to a 50% NOx reduction over conventional burners, and up to a 90% reduction when combined with flue gas recirculation (FGR) or over-fire air (OFA).


This versatile burner operates with low excess air (as low as 5%) and features adjustable flame shaping for customized performance. With a robust design and no moving parts under normal operation, the DFL™ burner ensures reliable, low-maintenance operation. Its capability to fire both liquid and gaseous fuels makes it suitable for a wide range of industrial applications.
