Diesel & Light Oil
Operate with pressure-atomizing burner systems at ambient viscosity. No preheating circuit is required, and cold-start follows the standard packaged-unit procedure.
The EPCB industrial oil fired steam boiler covers steam capacity from 0.5 to 20 T/H at rated pressure 0.7–1.6 MPa, built on a fourth-generation three-pass wet-back fire tube structure delivering combustion efficiency ≥95% and thermal efficiency up to 95%. Across the oil fired industrial boiler projects we deliver, the combustion system is matched to one fuel — diesel, light oil, or heavy oil — and configured before manufacturing begins. Every oil fired boiler ships factory-assembled and pressure-tested, with ISO 9001, CE, EAC, and SGS certification available depending on destination market and model.
A fire tube fuel oil boiler serves industrial facilities in chemical processing, pharmaceutical production, food and beverage, textile dyeing, and paper manufacturing where steam load falls within 0.5–20 T/H and operating pressure does not exceed 1.6 MPa. In the projects we scope, matching capacity to your continuous production load — not the connected peak load — is the first sizing decision we confirm before anything else begins.
| Steam Load | Typical Application | Rated Pressure |
|---|---|---|
| 0.5–2 T/H | Food processing, laundry, pharmaceutical pilot lines |
0.7 · 1.0 1.25 · 1.6 MPa — four rated tiers, available across all capacities |
| 2–6 T/H | Textile dyeing, pharmaceutical process heating, mid-size food plants | |
| 6–15 T/H | Chemical processing, large food or beverage production | |
| 15–20 T/H | Heavy industrial, multi-line facilities |
Above 20 T/H or 1.6 MPa? Water tube configurations apply and require a separate engineering review. If your demand sits near the 20 T/H boundary, share your peak load profile rather than an average figure so we can confirm before a design is committed.
Horizontal fire tube automatic oil fired steam boiler — rated parameters by model. Rated steam pressure (0.7 / 1.0 / 1.25 / 1.6 MPa) and steam temperature (170 / 184 / 194 / 204 ℃) apply across the full capacity range; all other values are model-specific.
The EPCB oil fired steam boiler is a three-pass fire tube boiler: flue gas flows inside the tubes while water is held outside the tubes in the shell. As with any oil fired boiler combustion equipment, oil combustion in the furnace requires fuel atomization — because the fuel enters in large quantity and in liquid form, it is separated into fine droplets so that every part of the fuel can be effectively ignited.
The three-pass wet-back layout is updated to its fourth generation, raising heat-energy conversion efficiency and reducing fuel consumption for stable operation under high-temperature, high-pressure conditions.

Parameters are for reference and may be adjusted to the final engineered configuration. The 0.5 T/H model and any customized variant are quoted on confirmation of project specification.
The fuel an oil fired boiler runs on determines the atomization system, burner specification, and ancillary equipment supplied with the unit. These are set during manufacturing and cannot be reconfigured after delivery — so we fix them at inquiry.
Operate with pressure-atomizing burner systems at ambient viscosity. No preheating circuit is required, and cold-start follows the standard packaged-unit procedure.
A heavy oil industrial steam boiler needs a preheating circuit to reduce viscosity before the nozzle stage. This adds equipment and changes the cold-start procedure — fuel viscosity grade and storage temperature must be provided as written inputs before burner selection is finalized.
A mistake we see often. When buyers assume that any oil fired boiler supports heavy oil without a preheating system, the burner underperforms at startup. Incomplete atomization accumulates soot on heat-exchange surfaces, raising fuel consumption and shortening service intervals. From experience, we require fuel viscosity grade and storage temperature as written inputs before burner selection — not after the unit ships.
It must be designed in from the start — retrofitting is not supported on standard packaged units. Flag this in your initial inquiry.
As an oil fired industrial boiler, the EPCB unit combines an updated heat-exchange structure, intelligent control, and an optimized combustion system — engineered for stable operation and a lower total cost of ownership across industrial applications.
The three-pass wet-back structure is updated to its fourth generation for more efficient heat exchange — improving heat-energy conversion, lowering fuel consumption, and reducing operating cost.
An advanced PLC control system enables fully automatic operation and precise temperature adjustment, reducing manual operation error and supporting safe, efficient running.
Precision burners ensure complete combustion and reduce fuel waste, lowering emissions and helping the facility comply with strict environmental regulations.
A simple, sturdy design with fewer wearing parts lowers failure risk and repair frequency. Combined with high combustion efficiency and widely available competitive fuel, it extends service life and delivers a higher return on investment.
EPCB oil fired steam boilers are backed by ISO 9001, CE, and EAC certification, together with an SGS supplier assessment. Coverage depends on model and destination market — always verify the certificate against your specific order.
How to verify your order is covered. Request the specific certification document — for example, the Declaration of Conformity for CE — and confirm that the model number and rated pressure listed match your purchase specification exactly. A certificate image on a product page that does not reference a specific unit confirms nothing about compliance for your order.
For Southeast Asian, South Asian, Middle Eastern, and African markets, import registration requirements vary by country and may include an in-country approval step outside the manufacturer's documents — confirm these before issuing the purchase order. Third-party inspection by Bureau Veritas, SGS, or TÜV can be coordinated before dispatch; include this in your initial inquiry so it can be scheduled before the shipment date is set.
Every custom industrial oil fired steam boiler we deliver moves through seven defined stages, with client sign-off at the drawing approval stage before manufacturing begins. Changes after that point affect both lead time and cost.
Establish actual process steam load, usage pattern, and peak-draw cycles.
Match boiler capacity and rated pressure to the confirmed production load.
Drawings are approved by the client before manufacturing begins. Changes after this point affect lead time and cost.
Lead time depends on capacity, customization depth, and the order queue at confirmation.
Each unit is pressure-tested and a factory test report is issued.
Bureau Veritas, SGS, or TÜV inspection before dispatch when the project or market requires it.
Guidance for installation and commissioning at the destination site.
Where delays really sit. In our experience with first-time importers, the longest schedule delays sit in customs documentation review and local installation permitting — not in manufacturing. We provide the full documentation package (factory test report, technical drawings, operation manual, applicable certification documents) to reduce clearance risk. If third-party inspection is required, factor its duration into your commissioning schedule at the outset.
An accurate custom quotation is possible only after the six inputs below are provided. Without them, any price or lead-time figure remains conditional and may shift once engineering begins.
Based on peak production load, not average demand — undersizing causes pressure instability during high-draw cycles.
Determined by process temperature requirements and piping design — not defaulted to the lowest available option.
Saturated or superheated — superheated steam requires a separate superheater stage and changes both system cost and layout.
Hardness, dissolved oxygen, and pH. If local water falls outside acceptable parameters, water treatment equipment must be specified alongside the boiler.
Diesel, light oil, or heavy oil — include viscosity grade and storage temperature for heavy oil.
Destination country and required certification — confirm import registration requirements before the purchase order is issued.
Fuel type must be specified before manufacturing. The burner and atomization system are set to your fuel specification during production and cannot be changed after delivery without replacing the burner assembly. If your site may require dual-fuel capability in the future, specify this at inquiry — it must be designed in from the start.
When steam demand exceeds 20 T/H, operating pressure exceeds 1.6 MPa, or the application requires high-temperature superheated steam for power generation. If your load profile is close to the 20 T/H boundary, confirm with our engineering team before scoping is finalized rather than after a design has been committed.
Request the specific certification document — for example, the Declaration of Conformity for CE — and confirm that it explicitly references the model number and rated pressure of your order. A certificate that does not identify the specific unit provides no verification of model-level compliance.
It is not included as a standard package item. Whether it is needed depends on your local water quality relative to the boiler's operating pressure rating. Share a local water analysis report during scoping so we can advise on whether a softener, deaerator, or chemical dosing system is required.
Standard documentation includes the factory test report, technical drawings, operation and maintenance manual, and applicable certification documents for your order specification. If your market requires third-party inspection, a Bureau Veritas, SGS, or TÜV report is issued before dispatch. Confirm local import registration requirements before issuing the purchase order — some markets require an in-country approval step that affects the overall delivery schedule.
Whether an industrial oil fired steam boiler is the right fit for your facility comes down to four variables — and feedwater quality and site conditions add further inputs that affect both the initial specification and long-term service intervals.
When buyers come to us with a rough steam demand figure and no load analysis, we open with a structured scoping session that establishes peak load, fuel parameters, site constraints, certification requirements, and target commissioning date before any design is committed to drawing. In our experience this is where cross-border boiler procurement most often goes wrong — discovering mid-engineering that fuel type, operating pressure, or certification scope does not match the quoted configuration. The later that surfaces, the more disruptive it is to resolve.
Our oil fired steam boilers are made to order rather than sold off the shelf — so instead of a fixed "oil boiler for sale" listing, share your steam capacity, operating pressure, fuel type, destination country, and any required certification. If third-party inspection or a specific market registration document is needed, include that in your first message so we can confirm coverage before scoping starts.
