How Does a Coal Fired Boiler Work?
The coal fired thermal oil boiler employs a fixed or moving grate combustion chamber to efficiently burn coal. The resulting heat is transferred to thermal oil that circulates through coils or tubes within the boiler. This heated oil, due to its high boiling point and excellent fluidity, can be delivered at precisely controlled temperatures (up to 320°C) to external process equipment. Unlike steam systems, thermal oil boilers operate at lower pressures, minimizing explosion risk and reducing maintenance needs (ScienceDirect).
- ✔ Heat transfer oil absorbs and stores energy, distributing it to heat-using systems.
- ✔ Excess heat cycles back to the boiler, maximizing fuel conversion efficiency.
- ✔ Modern systems use real-time monitoring to optimize combustion and reduce emissions.

FAQ: Professional Terms of Coal Fired Thermal Oil Boiler
1. What is the main material used for coal fired thermal oil boiler coils?
High-grade carbon steel (such as 20# or A106 Gr.B) or alloy steel is typically used for coil construction, providing excellent heat transfer and resistance to thermal stress.
2. Which international standards must be followed during installation?
Installations should comply with ASME Section I, EN12952, or GB/T industrial boiler standards, ensuring safety in design, pressure, and materials.
3. What are the available customization options for project-specific requirements?
Options include varying coil diameter, tube arrangement, multi-fuel grates, PLC intelligent controls, and add-ons such as economizers or dust collectors.
4. How often should the thermal oil be replaced and why?
Thermal oil should be analyzed every 6-12 months, with replacement typically required every 1–3 years, depending on use and contamination levels, to maintain optimal chemical properties.
5. What are the core advantages of forced circulation?
Forced circulation ensures uniform heat distribution, eliminates hot spots, and prevents risk of oil coking inside the coil tubes, extending service life.
6. How is boiler efficiency calculated in coal fired thermal oil boiler systems?
Efficiency = (Useful energy output / Fuel input energy) × 100%. Key factors: combustion completeness, heat recovery systems, and insulation type.
7. Are there environmental compliance requirements for coal fired thermal oil boiler operation?
Yes. Flue gas particulate emission and SO2, NOx must meet local regulatory standards, generally achieved via high-efficiency dust collectors and low-NOx burners.
