Dual‑Fuel Natural Gas & Chemical Oil Boiler – Reliable Heat for Heavy‑Duty Operations
The dual fuel natural gas and chemical oil boiler is engineered for continuous, high‑temperature steam generation in petrochemical plants, refineries, and large‑scale manufacturing facilities. By combining the clean‑burn efficiency of natural gas with the high energy density of chemical oil, this boiler delivers uninterrupted heat even when one fuel source fluctuates, ensuring process stability and minimizing downtime.
How It Works – Seamless Fuel Switching
The unit incorporates an advanced dual‑fuel control system that monitors inlet pressure, temperature, and combustion quality in real time. When the primary natural‑gas line experiences pressure drops or supply interruptions, the controller automatically initiates a transition to the chemical‑oil circuit within seconds, maintaining a constant flame and steam output. Integrated sensors and a programmable logic controller (PLC) provide diagnostic data to the plant’s SCADA system, allowing operators to fine‑tune combustion parameters for optimal efficiency.

Application Scenarios – Where Performance Matters
- Petrochemical distillation columns that require steady steam pressure for reflux and stripping.
- Refinery catalytic cracking units where rapid heat recovery is essential for process turn‑around.
- Large‑scale food‑grade sterilization lines needing precise temperature control without fuel‑supply interruptions.
- Power‑generation auxiliary heating where dual‑fuel capability reduces reliance on a single fuel market.
Because the boiler can be configured for both vertical and horizontal layouts, it fits into existing plant footprints, simplifying retrofits and new‑build projects alike.

FAQ – Quick Answers for Procurement Teams
What is the minimum order quantity (MOQ) for a custom‑spec dual fuel natural gas and chemical oil boiler?
We accept projects from a single unit upwards; however, a 5 MW base configuration is the standard starting point for custom engineering.
Can the boiler be tailored to specific pressure or temperature requirements?
Yes. Our engineering team can adjust pressure ratings up to 3 MPa and steam temperatures up to 540 °C, based on the client’s process data.
What is the typical lead time from order confirmation to shipment?
Standard lead time is 15–45 days, depending on capacity and optional accessories. Expedited programs are available on request.
What warranty and after‑sales support are provided?
All units ship with a 24‑month comprehensive warranty covering materials and workmanship. Extended service contracts and on‑site spares can be arranged.
