EI-GNQ Special Axial-flow Type Burner for The Asphalt Mixing Plant

1. Designed for Asphalt Mixing Plant Heat Demand

Asphalt production requires a thermal source that can withstand:

• Large and rapid temperature fluctuations

• Abrasive dust environments

• Long production cycles without shutdown

• Variable fuel availability

The EI-GNQ burner is engineered as a dedicated heating solution for asphalt drum mixers and batch plants, where flame stability directly determines drying efficiency, fuel consumption, and overall plant output. Its combustion structure allows heat to be delivered deep into the drying drum with minimal thermal loss.

2. Gas & Oil Dual-Fuel Operating Logic

The EI-GNQ series supports both gaseous fuel and liquid fuel within the same burner platform, allowing operators to adapt instantly to different energy supplies.

This dual-fuel logic enables:

• Free switching between gas and oil according to fuel availability

• Stable ignition under both combustion modes

• Flexible energy cost control in different regions

• Continuous production even during temporary fuel supply limitations

Rather than being locked to a single energy source, the system is built as a fuel-adaptive combustion unit for diversified plant environments.

3. Axial-Flow Combustion Structure

The defining feature of this series lies in its axial-flow flame formation principle.

Unlike conventional radial flame burners, the axial-flow structure:

• Directs the flame straight along the burner axis

• Produces a long, concentrated, and high-energy flame core

• Enhances heat penetration inside the drying drum

• Reduces unstable turbulence at the flame root

This structure is particularly suited to asphalt aggregate drying, where uniform heat exposure directly affects moisture removal efficiency and finished mixture quality.

4. High-Power Output Coverage: EI300GNQ to EI3000GNQ

The EI-GNQ range is structured to serve both medium and large asphalt plants through a progressive power ladder:

• EI300GNQ → 3,750 kW

• EI600GNQ → 7,000 kW

• EI1200GNQ → 13,500 kW

• EI1800GNQ → 21,000 kW

• EI2500GNQ → 27,000 kW

• EI3000GNQ → 31,000 kW

This wide coverage allows one burner series to support:

• Small batch asphalt stations

• Medium continuous mix plants

• Large-scale high-throughput asphalt production lines

5. Dual Energy Consumption Adaptability

Each model provides both gas consumption and oil consumption operating references, allowing precise matching to different heating demands:

• Gas energy suitability for clean and rapid startup

• Oil energy suitability for high-density heat output

• Balanced flame stability under transitional load conditions

This makes EI-GNQ suitable for regions where fuel infrastructure varies or where dual-fuel redundancy is required for risk control.
