Gas-Fired Burner Solutions

Advanced Ultra-Low NOx Combustion Systems for Clean, Efficient and Reliable Power

Tightening emissions and carbon reduction regulations are compelling power stations and operators of large combustion plant to make signifcant changes. Converting from coal to gas or upgrading old gas-fired units with new RJM ultra low NOx CleanAir Burner™ technology is enabling power stations and industrial plant to maintain cost-effective, low emission generation with reduced carbon emissions.

RJM’s can adapt its gas-fired CleanAir Burner™ technology to suit any plant whrther single or multi-burner configurations. In addition, the RJM CleanAir Burner™ can be designed to fire a mix of gases, such as Coke Oven Gas, Blast Furnace Gas as well as natural gas. Today RJM also offers an enhanced level of future-proofing by incorporatng a hydrogen-firing capability within its new burners.

Navigating Modern Gas Combustion and Emissions Demands

Switching to cleaner gas firing or retrofitting legacy boilers introduces unique operational and regulatory complexities. Operators must maintain flame stability across wide load ranges while preventing operational issues such as acoustic resonance, flashback, and thermal hotspots.

Furthermore, plant engineers face mounting pressure to future-proof their assets for hydrogen co-firing and shifting gas qualities.

Key operational hurdles faced by gas-fired plant operators include:

Complying with aggressive, localized NOx and carbon compliance limits
Preventing combustion instability, burner pulsation, and flame detachment
Maximising turndown ratios without sacrificing thermal efficiency
Managing flame geometry to protect boiler waterwalls from localized overheating
Integrating multi-fuel or future low-carbon hydrogen gas blends safely
Minimising parasitic electrical loads and pressure drops across the windbox

Ultra-Low NOx Gas Burner Engineering & Optimisation

Precision-engineered combustion performance for industrial and utility boilers

RJM’s specialised gas burner solutions—including our market-leading ultra-low NOx gas and industrial gas burner ranges—are custom-engineered using advanced computational fluid dynamics (CFD) modelling. By optimising internal gas lances, swirl generators, and staged air introduction, we achieve superior flame shaping and rapid mixing that actively suppresses thermal NOx formation at the source.
