An asphalt production plant in Vietnam required a high-capacity, reliable, and stable drying system for the treatment of inert materials (aggregates) used in asphalt mixtures.

In asphalt production processes, precise and homogeneous moisture removal is critical to ensure product quality and process continuity. Therefore, the combustion system had to provide continuous, stable, and well-controlled heat output under demanding site conditions.

The main objective was to supply a robust burner solution capable of operating reliably in continuous duty, while maintaining consistent drying performance.

For this application, a GB-S 17 G MC gas burner was selected and integrated into the aggregate drying oven.

With a 17 MW thermal output, the burner was specifically configured to ensure efficient and uniform drying of inert materials.

The scope of supply included:

• Combustion system optimized for inert material drying ovens
• 17 MW high thermal capacity ensuring stable heat generation
• Heavy-duty industrial design suitable for continuous operation
• Optimized air and process integration for homogeneous temperature distribution
• Compatibility with industrial automation and safety systems

After installation and commissioning, the plant achieved the following results:

• Efficient and uniform drying of aggregates and inert materials
• Improved asphalt production quality and process stability
• Increased production performance thanks to high thermal capacity
• Stable combustion behavior and reliable long-term operation
• Consistent performance under challenging site and environmental conditions

• High-capacity and reliable burner solution for asphalt plants
• Homogeneous drying leading to improved product quality
• Heavy-duty design for continuous industrial operation
• Reduced operational risk and high system availability
• Proven reference application for asphalt and road construction industries
