The crude oil heater is a key process heater in an atmospheric and vacuum distillation unit, primarily used to heat crude oil to the required temperature before it enters the fractionation tower. It directly determines the separation efficiency, product yield, and continuous operation capability of the unit.
Unlike standardized heating equipment, our crude oil heater is designed with project feasibility and long-term operational stability as its core design logic. All designs are reverse-engineered to meet EPC site construction conditions, maintenance logic, and operational risks. The equipment not only meets the heat load requirements but also ensures it can be installed quickly and stably.
product Advantages
Furnace heat load is not based on empirical values, but rather on "back-calculation design under crude oil conditions."
We don't select furnace types according to templates. Instead, we recalculate the heat flux distribution of the radiant and convection sections based on your crude oil flow rate, density, sulfur content, design outlet temperature, and allowable coking cycle. This controls the furnace tube metal temperature below the coking critical point, enabling the crude heater to operate continuously under high loads for extended periods, rather than "starting to coke immediately after commissioning."
This extends the decoking cycle, reduces furnace tube scrap rate, and improves the separation stability of the distillation tower.
Furnace tube life is designed for 10 years of continuous operation.
All furnace tube selections are based on design metal temperature, sulfur corrosion and high-temperature oxidation data, and crude oil salinity and sulfur content. Wall thickness is uniformly checked based on a design life of over 10 years, not a minimum standard of "meeting the minimum requirement for one-time delivery."
This reduces the frequency of mid-term overhauls and replacements, lowering the overall lifecycle cost of the unit.
The structure is designed from the outset for "on-site construction feasibility."
This avoids secondary cutting, rework, and delays on-site, which is the fundamental reason why many fired heater projects truly exceed their budgets. 4. Thermal efficiency is not a advertised value, but a deliverable energy-saving result.
Our products can improve overall thermal efficiency to approximately 90% (calculated based on actual projects), significantly reducing fuel gas consumption and directly reducing refinery operating costs.
Complete set of engineering documents delivered in one go, high first-time approval rate for drawings.
We provide complete thermal calculation sheets, material traceability, structural calculations, installation drawings, maintenance manuals, and third-party inspection interface documents.
This makes EPC technical evaluation, supervision review, and owner FAT easier to pass, shortening the project approval cycle.
Retrofit-friendly, no need to overhaul the original system.
We support crude heater replacement and upgrades without major pipeline alterations or civil engineering changes, significantly reducing downtime and construction risks for retrofit projects.

Customization and Service
Why choose us
In fired heater procurement, the true determinant of a project's success is never "who's cheaper,"
but rather, who can reduce your project risk, ensure a more stable schedule, simplify technical processes, and clarify responsibilities.
Our value lies precisely in this.
We start "eliminating technical risks" for you from the RFQ stage.
Many projects don't encounter problems during construction; rather, hidden dangers are already present in the RFQ stage.
We can intervene before you submit your inquiry:
Verify the reasonableness of the process datasheet
Identify potential risks such as coking, overheating, and corrosion
Provide suggestions for optimizing technical deviations
Assist EPC in reducing unnecessary overspec
Help you win the bid while avoiding the risks of later changes, rework, and claims.
Our designs are "responsible for construction," not just "responsible for manufacturing."
Each crude heater is designed with:
Segmented hoisting design
Center for gravity and hoisting points verification
Installation access and maintenance space provision
Burnhouse tube replacement path design
You receive not just a set of drawings, but a practical engineering solution ready for immediate implementation on-site.
Engineering capabilities specifically designed for retrofitting and confined space projects
We have extensive experience serving old refinery expansions, unit upgrades, space-constrained units, and high-corrosion/high-sulfur crude oil systems.
We are not a "standard furnace manufacturer," but an expert manufacturer specializing in non-standard, complex projects.
One-on-one project manager responsibility system
Each project is assigned a dedicated project manager.
Installation and commissioning: We are responsible for the results.
Delivery is not "finished" until the unit is successfully commissioned.
Full lifecycle service, not a one-time transaction
You receive not just after-sales calls, but a long-term fired heater technical partner.
Packaging and Shipping
Modular, disassembled export packaging, complete with hoisting diagrams, weight distribution diagrams, and all necessary documents. On-site installation is available upon arrival.
If you are looking for a Crude Fired Heater that is easy to install, operate, and maintain for your refinery's atmospheric and vacuum distillation project, please send us your datasheet or process conditions. We will provide you with an executable, auditable, and deliverable engineering solution.
