Our industrial coal fired thermal oil boiler factory delivers reliable, high‑efficiency heat transfer for continuous‑process plants, petrochemical refineries, and large‑scale metal treatment facilities. Designed for demanding duty cycles, each boiler converts solid coal into a stable, high‑temperature thermal oil circuit, providing consistent heat up to 400 °C while minimizing fuel consumption and emissions. Engineered in‑house, the units are fully customizable to meet the specific load, pressure, and space constraints of any industrial installation.

Whether you need a 500 kW system for a medium‑size plant or a 10 MW solution for a sprawling complex, our factory’s modular design philosophy ensures quick scale‑up, easy maintenance, and straightforward integration with existing process control infrastructure.

Application Scenarios

• Continuous heat treatment of steel billets and plates – maintaining uniform oil temperature for precise surface hardening.
• Large‑volume solvent recovery systems where high‑temperature oil circulation reduces vapor pressure and improves condensate yield.
• Petrochemical cracking units that require stable thermal oil loops to pre‑heat feedstock before catalytic conversion.
• Cement kiln pre‑heaters where coal‑fired oil boilers supply supplemental heat without disrupting kiln balance.

The versatility of our design allows retro‑fit into existing plant layouts or incorporation into new greenfield projects, with optional low‑NOx burners and automated fuel feed systems to meet stringent environmental standards.

Competitive Advantages

• Modular Construction: Standardized pressure vessels, burners, and oil circuits enable fast assembly and future capacity expansion.
• Fuel Flexibility: Optimized for high‑ash, low‑grade coal while retaining the ability to switch to biomass or blended fuels with minimal hardware changes.
• Energy Efficiency: Integrated economizer and flue‑gas heat recovery raise overall boiler efficiency above 85 % (higher heating value).
• Robust Control: PLC‑based automation with Modbus/TCP, Profibus, and optional DCS interfaces for seamless plant integration.
• Long Service Life: High‑temperature resistant alloys and reinforced oil‑circulation piping guarantee 20 + years of reliable operation under continuous load.

FAQ

What is the minimum order quantity (MOQ) for a custom‑designed boiler?

Our factory can accommodate single‑unit orders for pilot or demonstration projects. For full‑scale production, the typical MOQ starts at one complete boiler system, including all auxiliary equipment.

Can the boiler be adapted for alternative fuels?

Yes. The burner design is modular; we can retrofit a low‑NOx biomass or coal‑biomass blend burner without redesigning the core pressure vessel. Engineering drawings and performance curves are provided for each fuel option.

What is the typical lead time from order to shipment?

Standard models are delivered within 30‑45 days after receipt of a confirmed purchase order and down‑payment. Fully custom specifications may require 60‑90 days, depending on the complexity of the design and material availability.

Does the product include a warranty or after‑sales support?

All boilers are covered by a 12‑month warranty against manufacturing defects, plus a 5‑year optional extended service contract covering periodic inspections, spare‑part supply, and on‑site technical assistance.
