Product Introduction
The EC Series Multi-Fuel Burner is engineered for asphalt mixing plants that require maximum energy flexibility and stable combustion performance across diverse fuel types. Designed to operate efficiently with coal, gas, or oil, the EC series enables asphalt producers to switch fuel strategies according to availability, operating cost, and regional energy policies—all without replacing core system components.
Through an electronically controlled proportional system, the burner continuously adjusts fuel and air supply to maintain stable flame characteristics under varying load conditions. Whether running on solid fuels like coal, clean-burning natural gas, or liquid fuels such as diesel and heavy oil, the EC series delivers dependable thermal output for 500–5000 t/h asphalt plant configurations. This adaptability makes it ideal for global projects where fuel conditions often change during long-term production or across different job sites.
Product Advantage
A unified burner system that supports three major fuel categories, enabling seamless adaptation to regional energy structures and long-term project fluctuations.
Advanced digital regulation ensures balanced fuel–air supply for each fuel mode, optimizing combustion quality and reducing manual intervention.
Engineered to deliver consistent heat output across small, medium, and large asphalt plant models without sacrificing combustion efficiency.
Coal feed channels, gas pipelines, and oil circuits are integrated into a consolidated structure, simplifying installation and minimizing cross-system interference.
Load-based control reduces unnecessary fuel burn and maintains flame stability even under rapid production changes or variable moisture content in aggregates.
Switch among coal, gas, and oil depending on market price, onsite availability, or regulatory requirements—allowing operators to maintain cost stability all year round.
Energy supply interruptions are less likely to halt production, as the burner can be quickly converted to an alternative fuel without hardware changes.
By optimizing combustion efficiency and enabling fuel substitution, the EC series helps significantly reduce total fuel expenditure across long production cycles.
Ideal for regions where energy sources vary—such as Africa, South America, Central Asia, or remote construction sites relying on temporary fuel logistics.
A single burner system supports multiple project types & energy scenarios, extending its lifecycle value and decreasing reinvestment requirements.

FAQ
Yes. The EC series is built for cross-fuel operation, allowing users to switch between coal, gas, and oil using the same burner hardware, with only control parameters needing adjustment.
No. The electronic proportional control system recalibrates fuel–air ratios instantly, maintaining stable flame temperature regardless of the selected fuel.
coal mode uses a high-efficiency combustion pathway designed to maintain strong heat penetration, ensuring comparable thermal performance to liquid and gaseous fuels.
Coal requires more frequent cleaning due to ash content, while gas mode offers the cleanest operation. Oil mode requires periodic inspection of atomization components.
Yes. Gas mode provides the cleanest emissions, and oil/coal modes operate with optimized combustion systems designed to meet regional standards when paired with proper filtration and dust-collection equipment.
