Rapid Mix Burner (RMB™)
Get Ultra-Low Emissions From
Natural Gas-Firing Boilers.
Initially, ultra-low NOx levels could only be achieved with SCRs — and
hefty price tags. But for the past two decades, the RMB system has
been offering a reliable, more affordable solution. With its revolutionary
rapid-mix technology, the Rapid Mix Burner has become a proven
alternative to the catalytic control of NOx emissions, cutting both
costs and space requirements.

Breakthrough Thinking for Advanced Performance
The innovative technology in the RMB system is a result of “startover” thinking on how to avoid the fundamental conditions for
NOx formation:
++ Fuel-rich regions with their potential for prompt NOx formation
++ Higher flame temperatures that produce thermal NOx

Our solution: a radically different gaseous injection and
mixing system that utilizes:
++ Rapid mixing of combustion air and fuel gas prior
to the ignition point
++ Burner geometry that produces an
extremely stable flame
++ The introduction of flue gas recirculation
(FGR) to dramatically reduce peak
flame temperatures

RMB System At A Glance
• Less than 9 ppm NOx (18 mg/Nm3)
• Less than 25 ppm CO (31 mg/Nm3)
• Less than 3 ppm VOC (2 mg/Nm3)
• Easy installation and start-up
• Elimination of impingement due to a compact,
short flame
• Increased reliability and reduced maintenance
due to no-moving-parts design
• Streamlined air quality permitting tasks and
opportunities for emission-reduction credits
• Heat inputs to 300 MMBtu/hr (90 MW)
t per burner
• Ideal for a variety of applications
