Low-Emission Utility
Boiler Burners
Raising The Standard For
Lowering Emissions.
Our Divided Flow Low-emission (DFL) burner and Dynaswirl-LN™
burner are industry standards, optimizing system efficiency and
emissions performance with low-maintenance requirements.
Both burners are proven to achieve low NOx, CO, particulate and
opacity emissions, easily keeping your facility in compliance with
environmental regulations.
The simple design and heavy-duty construction of both the DFL and
Dynaswirl-LN burner provide reliable, low-maintenance performance.
Each is easy to maintain, resulting in less downtime and reduced fuel
and operating costs.
