Product Introduction
The EI-NQ Heavy & Light Oil Axial-flow Burner is purpose-built for asphalt mixing plants that rely on stable, controllable oil combustion. With an operating oil consumption range from 300 to 2800 kg/h, it precisely matches the thermal demand of 500–5000 t/h class asphalt plants.
Instead of focusing on gas modulation, EI-NQ is optimized for heavy oil and light oil atomization efficiency, ensuring consistent flame shape, steady heat output, and predictable fuel usage even under fluctuating site conditions. It is the ideal solution for regions where oil-based energy remains the primary fuel source.
Features
Ensures accurate matching with different asphalt plant capacities, preventing issues such as fuel oversupply in smaller plants or insufficient heating in larger units.
Supports both heavy oil and light oil in a single burner platform, giving customers greater flexibility in fuel sourcing and reducing dependence on a single energy type.
Generates finer oil mist for more complete combustion, delivering higher thermal output per unit of fuel and improving overall energy efficiency.
Automatically adjusts oil delivery based on real-time load demand, eliminating manual tuning errors and reducing unnecessary fuel consumption.
Achieves low-emission performance without the need for FGR, lowering compliance costs and simplifying environmental management.
Maintains steady oil consumption and consistent flame characteristics under continuous heavy-duty mixing operations, ensuring stable production cycles.

FAQ
It refers to the real adjustable oil usage per hour, allowing the burner to operate efficiently across small to super-large asphalt plants without over-burning or under-heating.
No. It fully supports both heavy oil and light oil, and the system is designed to maintain stable atomization quality for both fuels.
By automatically matching oil supply to actual thermal demand, EI-NQ avoids excess fuel injection, directly reducing daily operating fuel expenses.
The electronic proportional control system dynamically tracks load changes, so oil consumption adjusts in real time, keeping flame output stable.
Yes. With VIC ultra-low nitrogen oil combustion technology, NOx emissions can be kept within 30 mg, meeting multiple international standards.
