EC-NQR Series of Low-nitrogen Burners

Product Description

A Low-Nitrogen Burner is an advanced combustion device designed to minimize NOx emissions through optimized air–fuel mixing, staged combustion, precise flame control, and intelligent electronic regulation. It enables industrial systems to meet strict environmental standards while maintaining high thermal efficiency and combustion stability.

The EBICO EC-NQR Series Low-Nitrogen Burners are electronically proportional controlled burners developed under European design principles of safety, energy saving, environmental protection, and intelligent control. Powered by EBICO’s cutting-edge VIC low-NOx technology, the EC-NQR Series achieves NOx ≤ 30 mg/m³ without FGR. Supporting multiple fuels including natural gas, LNG, LPG, CNG, heavy and light oil, and coal fines, the EC-NQR Series delivers stable, efficient, and environmentally compliant combustion for industrial boilers and thermal systems.

Product Advantage

1. Ultra-Low NOx ≤ 30 mg/m³ Without FGR

Powered by VIC ultra-low-nitrogen combustion technology, EC-NQR achieves NOx emissions ≤ 30 mg/m³ without flue gas recirculation, simplifying system design and reducing operating costs.

2. Wide Power Range for 4–120T Industrial Boilers

Covers an output range from 3,900 kW to 86,000 kW, precisely matching 4T to 120T boiler capacities, making model selection straightforward for any project scale.

3. Multi-Fuel Compatibility for Flexible Energy Use

Supports natural gas, LNG, LPG, CNG, heavy oil, light oil, and coal fines, allowing users to adapt to local fuel availability and price fluctuations.

4. Electronic Proportional Control for Stable Combustion

Equipped with electronic proportional adjustment, ensuring precise air-fuel ratio control, stable flame performance, and high combustion efficiency under varying loads.

5. High Combustion Efficiency with Optimized Fuel Consumption

Oil consumption ranges from 350 to 7,720 kg/h, delivering reliable thermal output with optimized fuel utilization across all operating conditions.

Engineered for Heavy-Duty Continuous Operation

Designed for industrial-grade continuous duty, EC-NQR burners maintain stable ignition, uniform flame structure, and consistent heat output for long-term boiler operation.
