Product Introduction
The EI-G Asphalt Mixing Plant Burner is designed for asphalt mixing plants that use gas as the primary burner fuel. Its six-model range extends from EI300G to EI3000G, covering published output capacities from 3,750 kW to 31,000 kW.
Rather than treating the burner as an isolated heat source, the EI-G combines combustion-air supply, gas regulation, mixing and control functions into an integrated system. This makes it suitable for matching with asphalt drying drums where heat demand changes with production load and aggregate conditions.
The series uses an axial-flow fan arrangement together with regulated gas supply and PLC-based control. This allows the combustion system to coordinate air and gas delivery as burner demand changes.
Features
The axial-flow arrangement is one of the defining features of the EI-G Series.
Combustion air moves along the burner axis toward the combustion zone, supporting a concentrated flame path suited to the geometry of asphalt drying equipment. In an asphalt plant, flame shape has to work with the available drum space rather than simply produce the highest possible temperature.
The original EI-G design combines this air-supply arrangement with an H-shaped combustion structure. Together, these elements are intended to maintain a defined flame profile as heat demand changes during aggregate drying.
Actual burner-to-drum matching should still take account of dryer dimensions, production rate, aggregate moisture and required operating temperature. These factors influence the thermal load that the burner must meet in real production.
Stable gas combustion depends on controlling both fuel flow and combustion air.
The EI-G uses frequency and pressure regulation together with PLC-based independent control of fuel and air. Instead of relying on one fixed setting across the complete firing range, the system can adjust these inputs as burner load changes.
This is particularly relevant in asphalt production, where heat demand is rarely constant throughout an operating cycle. Startup, production changes and variations in aggregate condition can all require a different firing level.
The control arrangement is therefore designed around proportional burner operation rather than simple on/off heat delivery.
Final commissioning remains important. Gas properties, supply pressure, drum conditions and actual production demand should be checked on site so that the combustion settings correspond to the installed system.
A turbine-type mixer is used in the EI-G combustion assembly to promote the mixing of gas and combustion air before and during flame formation.
Good mixing is important because uneven fuel-air distribution can affect ignition, flame stability and usable heat delivery. The mixer works together with the axial-flow air arrangement and H-shaped flame structure to create the combustion pattern used by the EI-G Series.
This design is intended for the sustained heating requirements of asphalt aggregate drying rather than intermittent light-duty heating.
The burner should still be configured according to the actual dryer. Flame length and firing conditions need to remain compatible with the available combustion space to avoid treating burner output as the only selection criterion.
The EI-G is built as an integrated burner assembly incorporating the main burner body, combustion-air section, gas components, control-related equipment and supporting base.
The consolidated layout simplifies the engineering review when a burner is being matched with a new asphalt plant or considered as a replacement for an existing unit.
The gas train is positioned directly around the burner assembly, while electrical and control components are arranged for access from the side of the unit.
For project planning, overall installation dimensions, connection position and maintenance clearance should be confirmed before the burner configuration is finalized.
Viewed from the fan side, the EI-G shows the large axial-flow air section positioned in line with the burner body.
This layout provides the combustion-air path required by the axial-flow burner structure while keeping the main burner components on a common support frame.
The arrangement is useful for plant engineers assessing available installation space, particularly on retrofit projects where an existing burner platform or dryer connection may already define the allowable footprint.
Adequate clearance should also be left around the air intake and service areas. Restricted airflow or insufficient maintenance access can create avoidable problems after commissioning.
The front-end view shows the cylindrical burner connection and combustion outlet that interface with the asphalt plant drying system.
This part of the installation deserves careful attention during burner selection. Connection dimensions, drum geometry and the position of the combustion zone affect how the burner can be integrated into the plant.
For an existing asphalt mixing plant, drawings or clear photographs of the current burner-to-drum connection can help the technical team evaluate a replacement project before equipment is manufactured or shipped.
The EI-G also uses a movable pallet-style base, providing a practical structural arrangement for installation and servicing.
The EI-G combines its main combustion components on a common burner structure and incorporates several features intended to make plant-side handling more practical.
A straight cylindrical connection provides a defined interface with the heating equipment, while the movable pallet arrangement supports positioning and maintenance access. The original design also incorporates a silencer housing around the burner assembly to address operating noise generated by the combustion-air system.
For daily operation, accessibility should be considered during plant layout. Gas-system components, electrical connections, flame-monitoring devices, the air path and other service points need sufficient room for inspection.
Maintenance requirements will depend on operating hours, dust conditions, gas quality and the individual plant configuration. Regular inspection is preferable to waiting for a combustion problem to become visible in production.

The above configurations cover the full capacity spectrum required by medium to large asphalt mixing plants, ensuring precise matching between burner output and production scale.
Application
The EI-GNQ axial-flow burner is extensively applied in asphalt production and road construction scenarios where continuous high-temperature drying, heavy dust load, and long-duty cycles are common operating challenges.
It is fully matched with asphalt mixing plants of 500 / 1000 / 2000 / 3000 / 4000 / 5000 capacity classes, with a scalable power output ranging from 3.75 MW to 31 MW, ensuring precise thermal alignment with different production scales. This wide output coverage allows one burner series to support everything from medium batching plants to large continuous asphalt production lines without structural changes.
In road and highway construction projects, where aggregate moisture varies frequently and drying intensity must be adjusted in real time, the EI-GNQ’s gas & oil dual-fuel mode enables operators to balance energy cost and fuel availability while maintaining uninterrupted heating performance during peak construction periods.
For municipal pavement engineering and resurfacing works, the axial-flow flame structure provides deep heat penetration and uniform drum temperature distribution, improving aggregate drying efficiency and helping stabilize asphalt mixture quality under fluctuating site conditions.
The burner is equally suited for both portable and stationary asphalt batching plants, thanks to its movable pallet structure and straight cylindrical connection, which simplify on-site installation, disassembly, and relocation between different project locations.
In large-scale infrastructure projects and EPC road construction systems, where long-term continuous operation is required, EI-GNQ delivers stable axial flame output, strong thermal rigidity, and fuel adaptability, ensuring reliable drying performance even under high-dust, high-load, and non-stop production environments.
With its combination of high-power output, long axial flame, dual-fuel flexibility, and low-pressure stable combustion design, the EI-GNQ series provides a practical and efficient thermal solution for modern asphalt mixing and aggregate drying systems.
Selecting an EI-G model starts with the plant's actual heating requirement.
The published output rating provides the first reference, but several project conditions should be reviewed before the burner is finalized. These include asphalt plant specification, expected production rate, aggregate moisture, drying-drum dimensions, gas type and properties, gas supply conditions, site altitude, electrical supply and any applicable emission requirements.
Retrofit projects need several additional checks. The existing burner model, mounting dimensions, drum connection, available platform space and current control interface can all affect the replacement design.
Providing equipment drawings, plant photographs and operating data at the inquiry stage can reduce unnecessary back-and-forth during technical confirmation.
If the project requires both gas and oil capability, compare the EI-GNQ dual-fuel axial-flow burner. For plants operating on heavy or light oil, the EI-NQ axial-flow oil burner provides another configuration within the same application category.
Certifications
For industrial combustion equipment used in asphalt mixing plants, regulatory compliance, operational safety, and market access qualification are as critical as thermal performance itself.
The EI-GNQ series is developed and tested under a multi-standard compliance framework to ensure that each unit can be reliably deployed in projects with strict safety inspection, emission regulation, and engineering approval requirements across different regions.
To meet the diverse certification standards required by global infrastructure projects, the EI-GNQ series has passed the following international and national qualifications:
EU EN676 Gas Burner Standard – verifying burner safety integrity, ignition reliability, and combustion emission control
CE & ISO Certification – confirming compliance with European market entry regulations and international quality management systems
China CSEI Certification – approved for pressure-related equipment safety inspection and combustion system verification
Russia EAC Certification – meeting technical conformity requirements for the Eurasian Customs Union market
National Standard GB/T 36699-2018 – aligned with China’s official industrial burner technical specification
With this comprehensive certification coverage, the EI-GNQ axial-flow dual-fuel burner is well suited for both domestic engineering deployment and overseas EPC projects, even in regions with strict regulatory supervision and third-party inspection requirements.
The EI-G is presented as the gas-fired model in this product range. If both gas and oil operation are required, the fuel requirement should be specified before selection and a dual-fuel model such as the EI-GNQ should be evaluated instead.
A retrofit may be possible, but compatibility should not be assumed from output capacity alone. The existing burner connection, drum dimensions, mounting platform, gas system, electrical interface and required thermal output should be reviewed before a replacement model is confirmed.
Provide the asphalt plant model or specification, required production capacity, aggregate moisture if known, dryer or drum information, available gas type and supply conditions, site location or altitude, electrical requirements and information about the existing burner for retrofit projects.
No. Burner capacity should match the actual heat demand and usable operating range of the drying system. Choosing a substantially oversized burner does not remove the need for correct thermal and combustion matching.
The published consumption figures are model references. Actual use can vary with gas calorific value, aggregate moisture, production rate, required material temperature, burner load and combustion settings.
Routine inspection should cover the gas supply components, combustion-air path, fan section, ignition and flame-monitoring components, electrical connections and accessible burner surfaces. Maintenance intervals should reflect operating hours, dust exposure and site conditions.
