EBS-D Low Nitrogen Burner for Asphalt Mixing Plant

Product Description

The EBS-D Low Nitrogen Dual-Purpose Burner is developed for asphalt mixing plants that require simultaneous control of emission performance and multi-fuel adaptability. Unlike conventional single-fuel systems, EBS-D operates efficiently with gas, light oil, and heavy oil, allowing asphalt producers to maintain production continuity under changing fuel supply conditions.

Its combustion system is built around a multi-stage flame control architecture, combining directional airflow, internal pressure mixing, and segmented heat release. This enables the burner to maintain stable thermal output across 500–6000 class mixing plants, even when aggregate moisture, batch rhythm, or fuel quality varies during long-term operation.

Advanced Low-Nitrogen Combustion Architecture

1. “V”-Shaped Wind Tunnel Combustion System

The V-shaped airflow channel forms a rotational flame path rather than a straight fire jet. This design extends the residence time of fuel within the combustion chamber and strengthens radial air distribution, allowing heat to spread more evenly and preventing localized peak temperatures that normally accelerate NOx generation.

2. Negative Oxygen Secondary Combustion

A controlled oxygen-deficient zone is formed downstream of the primary flame. In this zone, residual combustible particles and CO are re-activated, completing their reaction process while suppressing secondary nitrogen oxidation. This improves combustion completeness without raising peak flame temperature.

3. Vacuum Internal Mixing Technology

Fuel is introduced under negative pressure conditions, producing high-density internal turbulence before ignition. This process enhances fuel droplet dispersion, especially under heavy oil conditions where viscosity normally limits atomization quality. The result is a more uniform flame core and steadier heat release during continuous operation.

4. Partitioned & Staggered Combustion Structure

The combustion chamber is divided into multiple functional zones with staggered ignition positions. Each zone is responsible for a different combustion phase, enabling progressive heat build-up rather than single-point ignition. This structural separation significantly increases flame controllability and thermal consistency across the full output range.

Dual-Purpose Design: Gas & Oil in One System

The EBS-D integrates gas and oil combustion into a single mechanical platform, eliminating the need for parallel burner systems:

• Gas mode is suitable for clean-energy projects and urban construction zones.

• Light oil mode offers high ignition reliability and flexible site deployment.

• Heavy oil mode supports low-cost, long-term continuous production.

Fuel conversion is achieved through control-side switching rather than physical reconfiguration, reducing downtime during energy transitions and simplifying spare-parts management.

Three-Way Energy Consumption Logic

Gas Consumption (Nm³/h)

Designed for rapid thermal response and low particulate discharge, ideal for projects with strict environmental constraints.

Light Oil Consumption (kg/h)

Provides strong ignition performance and high adaptability to fluctuating production loads, commonly used in mobile or transitional asphalt stations.

Heavy Oil Consumption (kg/h)

Optimized for projects with long continuous production cycles and lower fuel cost requirements, delivering robust thermal stability under high load.

The three consumption systems operate independently while sharing the same flame control structure, allowing operators to shift energy strategy without interrupting production rhythm.

Supported Asphalt Plant Scale

EBS-D is engineered to cover the entire mainstream asphalt production spectrum:

• 500–1000 plants: fast thermal response, accurate ignition control

• 2000–4000 plants: balanced output stability and fuel adaptability

• 5000–6000 plants: sustained high-load combustion with multi-fuel reliability

This ensures that one burner platform can serve multiple project phases or different job sites without structural replacement.

FAQs

1. Can EBS-D operate with mixed fuel supply conditions within one project?

Yes. EBS-D is designed to switch between gas, light oil, and heavy oil based on supply availability without requiring burner replacement.

2. Does heavy oil operation affect long-term combustion stability?

The vacuum internal mixing structure stabilizes heavy oil atomization, allowing long-hour continuous operation without flame drift or output fluctuation.

3. Is the burner suitable for asphalt recycling plants using reclaimed aggregates?

Yes. The staggered combustion structure adapts well to fluctuating moisture content typically found in RAP materials.

4. Can one operator manage both gas and oil modes safely?

Yes. Fuel mode switching is completed through the control interface, minimizing manual intervention and reducing operational error risk.

5. Does multi-fuel capability increase maintenance workload?

No. Shared combustion structures and unified ignition architecture reduce component duplication and keep routine maintenance procedures standardized.
