Edible Oil Refinery Coal Thermal Oil Boiler – Reliable Heat for Continuous Processing
Product Overview
The edible oil refinery coal thermal oil boiler delivers steady, high‑temperature oil heating essential for degumming, bleaching, and deodorisation stages in large‑scale edible oil production. Engineered for 24/7 operation, the unit converts low‑grade coal into a clean thermal oil circuit, eliminating the need for expensive steam infrastructure while maintaining tight temperature control (typically 260‑340 °C). Its modular design fits existing plant layouts, and the closed‑loop oil system reduces water usage and corrosion risk, aligning with sustainability targets in the food‑processing sector.
Built to meet ASME Section I & II standards, the boiler is supplied with a steel‑welded pressure vessel, a high‑efficiency burner, and a robust thermal oil pump. Optional accessories include automated fuel feeding, real‑time temperature monitoring, and a dual‑oil circulation system for redundancy during peak loads.

Competitive Advantages
- **High Thermal Efficiency** – up to 89 % LHV conversion reduces coal consumption and operating cost.
- **Robust Construction** – ASME‑certified pressure vessel, corrosion‑resistant alloy for long‑life service in aggressive oil environments.
- **Continuous Duty Capability** – designed for 8 000‑hour annual run‑time with minimal downtime.
- **Flexible Fuel Handling** – can accept a wide range of coal grades, including low‑calorific value stocks, providing supply security.
- **Integrated Safety Suite** – flame‑failure detection, over‑temperature shutdown, and pressure relief valves meet international safety codes.
- **Scalable Design** – modular boiler sections allow capacity expansion without major plant interruption.
Application Scenarios
The edible oil refinery coal thermal oil boiler is most effective in processes where precise, high‑temperature oil heating is mandatory and steam generation would be inefficient. Typical installations include:
- Degumming & neutralisation – rapid heat‑up of phospholipid removal vessels.
- Bleaching – maintaining uniform temperatures for activated‑clay contact.
- Deodorisation – providing continuous oil flow at 260‑340 °C for vacuum stripping.
- Fractionation – supporting high‑temperature column reboilers where steam is impractical.
- Cold‑store pre‑heating – preventing oil solidification during seasonal temperature drops.
Because the system uses a sealed thermal‑oil circuit, there is no direct contact between coal combustion gases and the process oil, ensuring product purity and compliance with food‑grade hygiene standards.
Frequently Asked Questions
What is the minimum order quantity (MOQ) for a custom‑spec boiler?
Our standard MOQ is one unit per model. For highly specialized configurations (e.g., dual‑fuel capability or bespoke control panels), a minimum order of two units helps optimise tooling costs, but we can accommodate single‑unit projects with a modest surcharge.
Can the boiler be adapted for alternative solid fuels?
Yes. While the baseline design targets bituminous coal, we offer retrofit kits for lignite, anthracite, or blended solid fuels. Modifications involve burner nozzle re‑sizing and ash‑handling adjustments, all performed under the same ASME certification regime.
What warranty and after‑sales support are provided?
Every boiler ships with a 24‑month comprehensive warranty covering material defects and workmanship. On‑site commissioning, operator training, and a 24/7 technical hotline are included. Spare‑part kits are stocked in major industrial hubs for rapid replacement.
How long does it take from order confirmation to delivery?
Typical lead time ranges from 15 to 45 days, depending on capacity, optional features, and current production load. Expedited engineering and shipping can be arranged for critical projects.
