Henan Taiguo Boiler Manufacturing Co., Ltd. recently completed a thermal oil heater project for an overseas asphalt and bitumen production facility. The client, a leading construction materials supplier in Southeast Asia, needed a reliable high-temperature heating system to ensure stable asphalt processing, lower production costs, and meet increasingly strict environmental regulations. Taiguo delivered a customized, energy-efficient solution that significantly improved the plant’s operational performance.
Project Background
The client required a stable heating source to maintain asphalt at 180–220°C during mixing, pumping, and storage. Their previous heating equipment suffered from temperature fluctuations, slow heat-up time, and high fuel consumption. Because asphalt quality is highly dependent on thermal stability, the customer urgently needed a modern, high-efficiency thermal oil system for long-term industrial operation.
Taiguo’s engineering team assessed the site’s layout, production scale, fuel type availability, and safety requirements before proposing a tailored upgrade plan. After evaluation, a 2.4 million kcal/h coal-fired thermal oil heater was selected, with optional auxiliary equipment including a heat conduction oil circulation pump, expansion tank, and intelligent temperature control system.
Solution Provided
Taiguo delivered a complete asphalt heating solution designed for continuous, high-temperature operation. Key features include:
• High thermal efficiency up to 92%, reducing fuel consumption
• Rapid heating performance for faster asphalt processing
• Stable temperature control to maintain consistent bitumen quality
• Fully automatic PLC control to simplify operation
• Multi-layer safety protection with pressure, temperature, and flow monitoring
• Compact system layout suitable for limited site space
• Internationally compliant components for easy maintenance and long equipment life
The system ensures smooth circulation of heat transfer oil and consistent temperature supply to the asphalt tanks, blending lines, and pipelines.
Project Results
After installation and commissioning, the customer reported a significant improvement in production stability and energy performance:
• Fuel consumption reduced by 18% compared with the old heater
• Asphalt heating time shortened by 25%
• Product quality became more uniform with fewer temperature-related defects
• Operators benefited from safer and more intuitive system controls
• Downtime due to overheating or temperature drops was eliminated
The thermal oil heater now operates 20+ hours per day during peak season, delivering reliable heating with minimal maintenance.
Customer Feedback
The client praised Taiguo for its quick delivery, professional technical support, and high manufacturing standards. They highlighted the heater’s stable output and low operating cost as major advantages for long-term asphalt production. The company has expressed interest in expanding cooperation for future bitumen tank upgrading and additional thermal oil systems.
Conclusion
This overseas asphalt heating project demonstrates Taiguo Boiler’s strong capability in serving international bitumen and construction material companies. With efficient thermal oil heating technology, customized engineering, and strict quality control, Taiguo continues to support global clients seeking reliable and cost-effective industrial heating solutions.
