Frequently Asked Questions

Q: What is the difference between a gas-fired and oil-fired steam boiler?

The primary difference is the fuel source. Gas-fired boilers use natural gas or LPG, typically offering cleaner emissions, while oil-fired boilers use diesel or heavy fuel oil, which can be more accessible in certain regions.

Q: How does the Aerogel insulation improve performance?

Aerogel provides significantly lower thermal conductivity than traditional rock wool, meaning less heat escapes the boiler shell, maintaining higher internal temperatures and reducing fuel needs.

Q: What does "steam dewatering" mean in the context of your boiler?

It refers to the separation of liquid water droplets from the steam. Our ultra-large design ensures only dry, high-quality steam enters your pipes, preventing water hammer and equipment corrosion.

Q: Can these boilers be integrated into existing steam networks?

Yes, with capacities ranging from 1 to 65 t/h and adjustable pressures up to 1.6 MPa, our boilers are designed to integrate seamlessly into most industrial steam distribution systems.

Q: How is the 95% thermal efficiency achieved?

This is achieved through a combination of the three-way threaded flue design for maximum heat transfer and the addition of a condenser and energy saver to recapture waste heat from exhaust gases.

Q: What maintenance is required for the WNS series boilers?

Regular maintenance includes water quality testing to prevent scaling, periodic burner calibration, and inspection of the Aerogel insulation to ensure maximum energy efficiency.
