| Shield | 400 – 16,000 kg/h (3 – 16 bar) | General industrial steam |
| Storm | 500 – 28,000 kg/h (3 – 16 bar) | High-pressure process steam |
| Strong | 2,000 – 150,000 kg/h | Large plants and central steam systems |
How Much Gas Does a Steam Boiler Use?
Approximate natural gas consumption at full load (10 bar(g), 80 °C feedwater, 92% efficiency, LHV 9.58 kWh/Nm³):
| Steam capacity | Thermal output | Gas consumption |
|---|---|---|
| 1 t/h | ~680 kW | ~77 Nm³/h |
| 2 t/h | ~1,360 kW | ~154 Nm³/h |
| 5 t/h | ~3,400 kW | ~385 Nm³/h |
| 10 t/h | ~6,800 kW | ~770 Nm³/h |
| 20 t/h | ~13,600 kW | ~1,540 Nm³/h |
Actual consumption depends on load profile, pressure, feedwater temperature and condensate return.
10 Ton Natural Gas Steam Boiler
A 10 t/h (10,000 kg/h) natural gas steam boiler produces roughly 6.8 MW of thermal output and is a common size for dairies, textile finishing, beverage plants and chemical processing. Ekotek offers this capacity in the Storm, Shield and Strong series, with a dual-fuel (gas/diesel) burner option for backup fuel security.
Advantages of Natural Gas Steam Boilers
- Clean combustion: lower CO₂, SO₂ and particulate emissions than oil or coal.
- High efficiency: three-pass design, with an optional economizer to recover flue-gas heat.
- Low-NOx burners: modulating burners with O₂ trim help meet local emission limits.
- Automatic operation: PLC touch panel, water level and pressure safety, remote monitoring.
- Low maintenance: no ash handling or fuel storage, with easy access for cleaning.
- Dual-fuel option: gas/diesel burners keep production running during gas supply cuts.
Efficiency and Heat Recovery
A flue-gas economizer preheats the feedwater and improves overall efficiency. Condensate return, good insulation and correct burner tuning reduce gas consumption further.
Boiler Room Equipment
A complete natural gas steam system includes the burner and gas train, feedwater tank and pumps, water softening and dosing, blowdown tank, steam collector and control panel. Ekotek can supply the full scope for your project. Contact our engineers for a tailored technical proposal.
Frequently Asked Questions (FAQ) about Natural Gas Steam Boiler
How much natural gas does a 10 ton steam boiler use?
About 770 Nm³/h at full load, assuming 10 bar(g), 80 °C feedwater and 92% efficiency. Real consumption depends on load and operating conditions.
What size natural gas steam boiler do I need?
Add up the steam demand of all consumers in kg/h, apply a diversity factor and a 10–20% safety margin, then choose the next standard boiler size.
Can a natural gas steam boiler also run on diesel?
Yes. With a dual-fuel burner the boiler can switch to diesel when the gas supply is unavailable.
Is a natural gas steam boiler better than an electric one?
For medium and large capacities, gas usually has lower operating costs. Electric steam generators suit small loads or sites that require zero on-site emissions.
