EC-GR VIC New Technology Low Nitrogen Burner for Boiler（1-2 TH）

Low-Nitrogen Burner (1–2 TH)

The EC-GR Low-Nitrogen Burner (1–2 TH) is a compact electronic proportional burner specifically developed for small-capacity industrial boilers and thermal oil heaters. It is designed to serve 1–2 ton steam boilers and 300,000–1.2 million kcal thermal oil systems, where stable heat output, low emissions, and precise control are critical.

Unlike large industrial burners, EC-GR focuses on small and medium heat-using equipment, offering a highly efficient and intelligent combustion solution for limited installation spaces. By integrating advanced low-nitrogen combustion technology with skid-mounted modular construction, EC-GR ensures easy deployment, fast commissioning, and low maintenance cost, making it an ideal choice for micro and small boiler users.

Features of EC-GR Low-Nitrogen Burner

• Ultra-Low NOx Without FGR

Achieves NOx < 30 mg/m³ without flue gas recirculation, simplifying system design and reducing operating complexity.

• Optimized for Small Boilers

Specially engineered for 1–2 ton boilers, ensuring high combustion stability even at low and medium loads.

• High Combustion Efficiency (≈100%)

Maximizes fuel utilization and minimizes heat loss, significantly reducing long-term fuel costs.

• Electronic Proportional Adjustment

Provides precise air–fuel ratio control, improving flame stability and thermal response performance.

• Multi-Fuel Adaptability

Compatible with NG, LNG, LPG, CNG, heavy oil, light oil, and coal fines, enabling flexible energy use.

• Intelligent Control System

Equipped with bilingual one-key menu, with optional analog frequency control (VFD simulation).

• Modular & Skid-Mounted Structure

Factory-integrated structure allows fast installation, compact layout, and efficient maintenance.

Technical

The EC-GR Series is precisely configured for small-capacity heat systems, ensuring accurate load matching and avoiding the inefficiency caused by oversized burners.

EC-GR Selection Guide

Choose EC1GR if:

• Your boiler capacity is 1 ton

• Heat demand is around 850 kW

• You need lower gas consumption (≈85 Nm³/h)

• Your system runs under light to medium thermal load

• Space is highly limited

Choose EC2GR if:

• Your boiler capacity is 2 tons

• Heat demand reaches 2000 kW

• You require higher continuous heat output

• Your production operates with long-time stable heating demand

• Future capacity expansion is expected

Selection Tip:

Always match the burner model to the actual boiler tonnage and thermal demand, rather than choosing a larger model blindly. Proper matching ensures higher efficiency, longer service life, and better emission control.

Application

The EC-GR Low-Nitrogen Burner is widely used in small to medium industrial heating systems, particularly where emission control and intelligent operation are required:

• 1–2T Industrial Steam Boilers

• Small Thermal Oil Heaters (300,000–1.2M kcal)

• Food Processing Workshops

• Packaging & Printing Lines

• Pharmaceutical & Laboratory Heating Systems

• Textile & Garment Production Lines

• Small Chemical & Material Processing Plants

• Low-NOx Boiler Retrofit Projects

Its compact size and intelligent control make it especially suitable for urban factories and limited boiler rooms.
