Recommended EPCB Series
WNS6-1.0-Q Gas Steam Boiler
3-Pass wet-back firetube design with European low-NOx burner & flue-gas condensing economizer.
• 1 T/H saturated steam (1.0 MPa, 184°C) ≡ 0.7 MW (600,000 kcal/h).
• Lower Calorific Values (LHV): Gas 8,500 kcal/Nm³, Biomass 4,000 kcal/kg, Diesel 10,200 kcal/kg, Coal 5,000 kcal/kg.
• Formula: Hourly Fuel = (Steam T/H × 600,000) ÷ (LHV × Thermal Efficiency).

How EPCB Sizes Industrial Boilers for Maximum ROI
Accurate boiler capacity sizing prevents common operational pitfalls: oversizing leads to high cycling losses, while undersizing causes catastrophic pressure drops during production peaks.
Process Heat Load Calculation
Total thermal enthalpy required to heat raw materials and maintain continuous evaporation at set production temperatures.
Pipeline & Loss Factor
A critical 15%–20% safety margin compensates for distribution transmission line radiation loss, valve drops, and flash steam venting.
Fuel Economy Optimization
Condensing economizers and air preheaters recover waste flue gas heat, raising feed water temperature from 20°C to 65°C+ for 8–12% fuel savings.
| Capacity | Equivalent MW | Natural Gas (Nm³/h) | Biomass Pellets (kg/h) | Diesel Oil (kg/h) | Recommended Series |
|---|---|---|---|---|---|
| 1 T/H (1,000 kg/h) | 0.7 MW | 72 ~ 75 | 165 ~ 180 | 60 ~ 65 | WNS / DZL Skid-Mounted |
| 2 T/H (2,000 kg/h) | 1.4 MW | 145 ~ 150 | 330 ~ 360 | 120 ~ 130 | WNS / DZL Packaged |
| 4 T/H (4,000 kg/h) | 2.8 MW | 290 ~ 300 | 660 ~ 720 | 240 ~ 260 | WNS / SZL Chain Grate |
| 6 T/H (6,000 kg/h) | 4.2 MW | 435 ~ 450 | 990 ~ 1,080 | 360 ~ 390 | WNS (Uzbekistan Case) / SZL |
| 10 T/H (10,000 kg/h) | 7.0 MW | 720 ~ 750 | 1,650 ~ 1,800 | 600 ~ 650 | WNS / SZL / DZL (Vietnam Case) |
| 15 T/H (15,000 kg/h) | 10.5 MW | 1,080 ~ 1,120 | 2,480 ~ 2,700 | 900 ~ 975 | SZL (Thailand Case) / WNS Arctic |
* Estimates based on standard lower calorific values: Natural gas = 8,500 kcal/Nm³, Biomass pellets = 4,000 kcal/kg, Diesel = 10,200 kcal/kg. Actual consumption varies with local fuel quality and feedwater temperature.
Frequently Asked Boiler Sizing Questions
How do I choose between a Steam Boiler and a Thermal Oil Boiler?
Choose a Steam Boiler if your process requires direct steam injection (sterilization, food cooking, textile steaming) or high latent heat transfer. Choose a Thermal Oil Boiler if you need temperatures above 180°C up to 350°C without the danger and high cost of operating high-pressure steam lines (ideal for wood drying, chemical synthesis, and asphalt heating).
What international certifications are required when importing an industrial boiler?
Standards vary by country: The Commonwealth of Independent States (Russia, Kazakhstan, Uzbekistan) mandates EAC TR CU 032/2013 certification for pressure equipment. The European Union requires CE-PED. North and South America frequently require ASME (S/U stamps). EPCB boilers carry ASME, CE, EAC, and ISO 9001 certifications.
Can EPCB design dual-fuel or multi-fuel combustion systems?
Yes. EPCB specializes in dual-fuel gas/diesel systems and multi-fuel biomass grates capable of co-firing wood chips, palm kernel shells (PKS), rice husks, and coal, safeguarding your plant against local fuel price volatility.
