With advanced production lines, precise testing facilities, and a strong commitment to technological innovation, a company required a highly stable and efficient heat source to support its growing industrial operations. To meet these stringent demands, ZOZEN Boiler supplied a 2 million kcal gas-fired thermal oil boiler, providing reliable, clean, and energy-efficient heating for various stages of rare earth material processing.

In rare earth metallurgy and processing, maintaining a stable and controllable heat supply is crucial. The melting, reduction, and refining processes all require precise temperature control to ensure consistent product quality and material performance. Any temperature fluctuation could compromise the purity or structural integrity of rare earth materials.

ZOZEN 2 million kcal gas-fired thermal oil boiler

The 2 million kcal gas-fired thermal oil boiler from ZOZEN operates at a working pressure of 0.8–1 MPa, achieving a maximum operating temperature of up to 320°C. Its closed-loop heat transfer system ensures uniform and continuous thermal delivery without the phase changes typical of steam systems. This stability allows Baotou Tianshi Rare Earth New Materials to maintain precise temperature regulation across multiple processing lines, ensuring both production consistency and higher yield.

Energy efficiency is a key factor in modern rare earth production, where continuous high-temperature operation can drive up energy costs. The 2 million kcal gas-fired thermal oil boiler is designed for thermal efficiency exceeding 92%, significantly reducing fuel consumption compared with traditional heating systems. Its optimized combustion chamber and multi-pass flue gas design enhance heat transfer and minimize exhaust losses.

The system is equipped with an intelligent automatic control system, which continuously monitors and adjusts oil temperature, flow rate, and pressure. This ensures optimal energy utilization and stable performance even under varying production loads. In addition, the control system includes interlock protections and fault alarms, providing real-time safety management. These features enable Baotou Tianshi to operate the boiler continuously and securely, minimizing downtime and maintenance needs.

As China advances toward greener and more sustainable industrial practices, the 2 million kcal gas-fired thermal oil boiler also contributes to environmental compliance. By utilizing clean-burning natural gas as its primary fuel and adopting low-NOx combustion technology, it effectively reduces nitrogen oxide emissions, helping the company align with local environmental regulations while maintaining efficient heat supply. The system’s closed circulation design also eliminates water loss and scaling, reducing environmental impact and improving long-term reliability.

With years of engineering expertise and deep experience across multiple high-tech industries, ZOZEN Boiler continues to provide advanced heating solutions for precision manufacturing sectors such as chemicals, materials, and energy. Its 2 million kcal gas-fired thermal oil boiler reflects the company’s dedication to technological advancement, energy conservation, and operational safety. From design optimization and delivery to on-site commissioning and training, ZOZEN ensures every project runs smoothly and efficiently.

For Rare Earth New Materials, this project not only improved process efficiency but also reinforced sustainable production capacity. With the stable performance of the 2 million kcal gas-fired thermal oil boiler, the enterprise can continue to expand its rare earth materials business with greater reliability and lower energy intensity.
