Custom EC-GR Series 3900–86,000 kW Low Nitrogen Burners (EC4GR–EC20GR)

Product Introduction

The Custom EC-GR Series low nitrogen burners are engineered for medium to ultra-large industrial boiler systems operating between 4 and 120 tons per hour. With thermal output ranging from 3900 kW to 86,000 kW, the series enables precise matching between burner capacity and boiler load, avoiding efficiency loss caused by oversizing.

By integrating VIC low-nitrogen combustion architecture with electronic proportional adjustment, the EC-GR Series maintains stable flame structure under fluctuating load conditions while achieving ultra-low NOx emissions without relying on flue gas recirculation. Its modular skid-mounted body structure allows flexible installation, fast commissioning, and long service life under continuous industrial operation.

Features

Wide Output Coverage for 4–120T Boilers

Output power ranges from 3,900 to 86,000 kW, precisely matching 4–120 ton industrial boilers, suitable for both medium and large-scale boiler rooms.

Ultra-Low NOx Without FGR Dependency

Maintains stable NOx emissions below 30 mg/m³ without flue gas recirculation, ensuring environmental compliance with a simplified system structure.

Electronic Proportional Regulation

Automatic air–fuel ratio control delivers smooth ignition, fast load response, and stable steam output across all operating conditions.

Optimized Gas Consumption Across All Models

Gas consumption spans 390–8600 Nm³/h, enabling accurate fuel matching and efficient operation under different production loads.

Multi-Fuel Industrial Compatibility

Supports natural gas, LNG, LPG, CNG, light oil, heavy oil, and coal powder, meeting diverse global energy supply conditions.

Skid-Mounted Modular Construction

Factory-integrated skid-mounted design reduces installation time, on-site commissioning complexity, and long-term maintenance costs.

Anti-Corrosion & Anti-Carbon Deposition Design

Effectively prevents condensation corrosion, nozzle blockage, and combustion chamber fouling during long-term continuous operation.

The Custom EC-GR Series is applied in high-load, continuous industrial heating systems requiring both output stability and environmental compliance:

• 4–8T Steam Boilers – food processing, packaging, washing plants

• 10–20T Process Boilers – textile dyeing, paper production, fermentation systems

• 25–40T Industrial Boilers – pharmaceutical, rubber, chemical material manufacturing

• 45–65T Central Heating Boilers – industrial parks, logistics heating centers

• 70–120T Energy Boilers – petrochemical plants, district heating, heavy industry

• Thermal Oil Systems (up to 120T equivalent) – asphalt production and chemical reactors

• Low-NOx Reconstruction Projects – emission upgrades on existing large boiler systems

Design and Inspection Standards for EBICO Burners

EBICO burners are designed and manufactured under multi-level international and regional technical conformity systems:

• Compliance with EU EN267 fuel burner standards

• Compliance with EU EN676 gas burner standards

• Certified under EU CE and ISO quality systems

• Certified by China CSEI special equipment inspection authority

• Conformity with Russia and Eurasian EAC regulations

• Fully aligned with China National Low-NOx Standard GB/T 36699-2018

Each EC-GR burner must pass multi-stage factory testing, load simulation, ignition verification, and emission measurement before delivery.

FAQ

Q1: Can EC-GR burners operate under partial load for long periods?

Yes. The electronic proportional control system is designed for stable long-term low and medium load operation without flame instability.
