    Description

    The Thermal Oil Boiler by Feiteng is engineered to deliver high-performance, safe, and efficient heating for various industrial applications. Utilizing diesel oil as the primary fuel and organic heat carrier (heat transfer oil) as the medium, this boiler ensures a stable heat source with output temperatures reaching up to 300°C. The closed-loop system uses a high-temperature oil pump to force continuous liquid-phase circulation, transferring thermal energy efficiently while maintaining pressure stability.

    The boiler features a high-efficiency burner (RIELLO), which ensures complete fuel combustion and low emissions, meeting and exceeding environmental standards. A PLC automatic control system guarantees precise temperature regulation, automatic fault detection, alarms, and shutdowns for full safety assurance.

    Its modular design allows for easy installation and maintenance. Custom fuel options such as natural gas, electric heating, coal, and horizontal or vertical configurations are available, supported by Feiteng’s expert engineering team.

    This boiler is widely applicable in bitumen production lines, asphalt mixing stations, chemical industries, and construction sites, offering a reliable and energy-saving solution for heat demand.

    Structure & Working Principle

    The thermal oil heating system is composed of a diesel oil burner, a thermal oil circulation system, and a smart control panel.

    ▶ Combustion System

    • High-efficiency Riello burner ensures full combustion of diesel fuel

    • Combustion gases heat the coils, indirectly heating the organic heat transfer oil

    • Flue gases are released through the chimney with optimized emission control

    ▶ Circulation & Transfer

    • Heated oil is pumped via high-temperature resistant oil pumps (flow rate: up to 160 m³/h)

    • The oil circulates in a closed-loop system, transferring heat to target equipment

    • The cooled oil returns to the boiler for reheating, maximizing energy reuse

    ▶ Control System

    • The system uses PLC intelligent control with digital display

    • Functions include: temperature adjustment, fault diagnosis, automatic start/stop

    • Optional features: remote monitoring, SCADA integration, over-temperature alarm, and emergency shutdown

    What is a thermal oil boiler used for?

    A thermal oil boiler is an industrial heating system designed for indirect heat transfer using heat-conducting oil. It’s widely used in applications where traditional steam boilers may be unsafe or less efficient, including bitumen heating, textile drying, plastic molding, and chemical reactors.

    Diesel vs Electric Thermal Oil Boilers

    While diesel thermal oil boilers are known for their rapid heating and high BTU output, electric boilers offer a zero-emission alternative suitable for indoor or sensitive environments. Feiteng offers both types and provides consultation to help you choose the best option for your needs.

    Q1: What is the heating time to reach 300°C?

    A: Depending on ambient temperature and oil volume, it usually takes 25~40 minutes.

    Q2: Can I use this boiler for bitumen melting and pumping?

    A: Absolutely. It’s designed for continuous heat supply, ideal for bitumen and asphalt applications.

    Q3: Is the system compatible with SCADA or remote control?

    A: Yes. Our boilers can integrate with your automation systems including SCADA or DCS platforms.
