Frequently Asked Questions

Q: What are the benefits of using biomass over coal in these boilers?

Biomass fuels offer a renewable energy alternative that significantly reduces carbon footprints and operational costs compared to traditional coal.

Q: How does the corrugated tube design improve performance?

The spiral corrugation increases the heat transfer surface area and creates turbulence in the water flow, leading to faster steam generation.

Q: How is the issue of boiler bottom bulging prevented?

By arranging ascending tubes under the drum, dead water zones are eliminated, ensuring the high-temperature region is effectively cooled.

Q: Can this boiler handle different types of biomass?

Yes, the reciprocating grate design is versatile and can handle various biomass fuels, including wood chips, agricultural waste, and pellets.

Q: What makes the combustion process more environmentally friendly?

The rational furnace arch design improves combustion efficiency and enhances the dust-failing effect, reducing particulate emissions.

Q: How is the air distribution managed for maximum efficiency?

A high-sealing wind box allows for flexible adjustment and reasonable air distribution, reducing the air excess coefficient.
