John Zink - Model ECOjet Edge+ -Ultra-Low NOx Boiler Burner
The Next Evolution in Ultra-Low NOx Combustion — Now as Low as 15 ppm Without FGR. Building on the proven success of the ECOjet and ECOjet Edge platforms, ECOjet® Edge+ is John Zink`s flagship ultra-low NOx boiler burner technology. With more than 350 ECOjet family installations worldwide, it carries forward the reliability and partnership customers expect from John Zink, backed by lifecycle support that ensures performance well beyond installation. Designed to anticipate regulatory shifts and evolving operating demands, ECOjet Edge+ is capable of achieving as low as 15 ppm NOx without FGR while maintaining the stability, turndown, and durability that make ECOjet burners trusted worldwide. It is more than future-ready. It is hydrogen proven, with active installations firing 100% natural gas to 100% hydrogen.
Ultra-Low NOx Performance
Achieves as low as 15 ppm without FGR in select applications, maintaining stable flame and low CO across the full turndown range.
Hydrogen-Proven and Fuel Flexible
Demonstrated 100% hydrogen firing with reliable operation across natural gas, waste gas, refinery gas, and heavy liquid fuels—including gas/oil co-firing for optimized fuel usage.
Retrofit-Ready Design
Fits existing ECOjet, ECOjet Edge, and many competitor burners with minimal modification, simplifying integration and reducing outage time.
Simplified Operation and Controls
Self-cleaning spark ignition, robust pilots, and a streamlined controls philosophy reduce moving parts and failure points for easier, more reliable operation.
Durable Construction, Easy of Commissioning and Maintenance
Lower tip count with removable access simplify service without furnace entry, while an all-metal throat extends life and resists damage.
Compliance without Complexity
Meet stringent NOx regulations without FGR or external controls, reducing system cost, space, and maintenance.
Lower Total Cost of Ownership
High-durability design, long service intervals, and efficient performance extend equipment life and reduce lifecycle costs.
Fast, Easy Upgrades
Retrofit-ready configuration enables quick installation and reuse of existing infrastructure, minimizing downtime.
Reliable Operation Across Loads
Stable flame and consistent emissions performance across the turndown range enhance operational confidence.
Future-Ready Performance
Hydrogen-proven capability helps operators transition to low- and zero-carbon fuels without changing core equipment.
