In modern industrial manufacturing, precise and stable heat supply plays a decisive role in ensuring product quality, process continuity, and energy efficiency. For industries that require high operating temperatures without the risks associated with high-pressure steam, thermal oil heaters have become a widely adopted solution. By using heat transfer oil as the medium, thermal oil heaters are capable of delivering consistent high-temperature heat under relatively low system pressure, which significantly improves operational safety and temperature control accuracy.

Within this technical context, ZOZEN Boiler has established itself as a reliable manufacturer of industrial thermal oil heaters. Drawing on extensive engineering experience and a deep understanding of industrial heating demands, ZOZEN provides customized thermal oil heater solutions that balance efficiency, fuel adaptability, operational stability, and long-term reliability. By focusing on practical engineering performance rather than short-term output metrics, ZOZEN thermal oil heaters have been widely applied across multiple industries.

ZOZEN YLW and YQW Thermal Oil Heaters: Fuel Options, Design, and Technical Advantages

The YLW biomass-fired thermal oil heater is designed for enterprises seeking to utilize renewable solid fuels to reduce energy costs and environmental impact. This type of thermal oil heater is compatible with a variety of biomass molded fuels, which are widely available and cost-effective in many regions. The YLW series adopts a horizontal structure with a square coil heating surface, allowing the heat transfer oil to absorb heat evenly as it circulates through the system. The compact and well-organized arrangement of heating surfaces enhances heat exchange efficiency and ensures stable outlet oil temperature, which is critical for processes requiring precise thermal control.

The combustion system of the YLW thermal oil heater is equipped with a chain grate that supports continuous fuel feeding and steady combustion. The grate structure is carefully designed to ensure uniform fuel distribution and sufficient residence time for complete combustion. By coordinating fuel feeding, air supply, and combustion control, the system achieves efficient energy utilization while reducing ash accumulation and combustion residue. The rational flue gas flow path further improves heat recovery from high-temperature exhaust gases, lowering heat loss and contributing to stable long-term operation.

In parallel, the YQW fuel and gas-fired thermal oil heater is designed for users who prioritize clean combustion, rapid response, and precise load regulation. This series supports fuels such as natural gas and fuel oil, offering high combustion efficiency and consistent thermal output. The YQW thermal oil heater features a coil-type heating surface arranged to maximize contact between high-temperature flue gas and the heat transfer oil. This configuration ensures uniform oil heating and smooth temperature rise, even under fluctuating load conditions.

The combustion chamber of the YQW series is designed with sufficient volume to promote complete fuel combustion, while advanced burner systems ensure stable flame formation and controlled air–fuel mixing. This design not only improves thermal efficiency but also helps maintain stable oil temperature and pressure throughout operation. As a result, YQW thermal oil heaters are well suited for industrial processes that demand continuous, precisely controlled heat input.

Both YLW and YQW thermal oil heaters are designed with safety and reliability as fundamental principles. The systems incorporate multiple monitoring and protection measures for oil temperature, pressure, and circulation status, ensuring that the thermal oil remains within safe operating parameters during long-term use. This engineering approach allows ZOZEN thermal oil heaters to meet the demanding requirements of industrial users without unnecessary operational complexity.

Case Application: YLW Thermal Oil Heater for Bestway Vietnam Factory

Based on a detailed assessment of the production requirements and local fuel conditions, ZOZEN Boiler supplied the Bestway Vietnam factory with a YLW series biomass-fired thermal oil heater rated at 10 million kcal. This system was specifically configured to meet the factory’s demand for continuous operation and precise thermal control. The thermal oil heater was equipped with a square coil heating surface and a horizontal chain grate, ensuring efficient heat transfer and stable combustion.

The square coil heat transfer structure allows the thermal oil to absorb heat evenly, reducing temperature gradients within the system and maintaining a stable outlet oil temperature. This design is particularly suitable for processes that rely on accurate and repeatable heating conditions. At the same time, the optimized flue gas flow path and energy-saving configuration enhance heat utilization and reduce exhaust heat loss, supporting efficient long-term operation.

To accommodate installation conditions and minimize on-site construction complexity, the thermal oil heater was supplied with the main body and chain grate arranged for convenient transportation and assembly. After positioning on site, the system could be commissioned through standard pipeline, valve, and electrical connections, significantly shortening the installation cycle and reducing civil engineering requirements. This approach allowed the Bestway Vietnam factory to bring the heating system into operation within a controlled timeframe, minimizing disruption to production planning.

The YLW thermal oil heater supplied to Bestway is designed to burn biomass molded fuels that are readily available and cost-effective. By optimizing fuel feeding and combustion parameters, the system achieves stable combustion, reduced ash generation, and controlled emissions. This enables the factory to balance energy efficiency with environmental considerations while maintaining reliable heat supply for demanding production processes.

This case demonstrates how ZOZEN thermal oil heaters can be tailored to meet specific industrial heating requirements through careful system design, fuel adaptability, and practical engineering solutions.
