Frequently Asked Questions

Q: What is the primary advantage of the DZL's spirally corrugated tubes?

The spirally corrugated tubes increase the heat transfer area and enhance the heat transfer coefficient, resulting in a faster steam rate and improved overall thermal efficiency.

Q: Can this boiler operate with biomass fuels instead of coal?

Yes, the DZL series is specifically designed as a coal or biomass fired boiler, allowing users to switch to sustainable biomass energy sources to reduce costs and carbon footprints.

Q: How does the design prevent the drum from cracking?

The boiler utilizes an arched tube sheet combined with corrugated tubes, which allows for better thermal expansion and stress distribution, effectively preventing cracking.

Q: What is the purpose of the ascending calandria arrangement?

This arrangement eliminates dead water zones at the bottom of the drum, making it difficult for sludge to subside and ensuring better cooling of the high-temperature drum region.

Q: How does the DZL boiler reduce air pollution?

Through a rational furnace arch design that improves combustion conditions and enhances the dust falling function, significantly reducing pollutant emissions.

Q: What is the typical efficiency range for the DZL series?

Depending on the model capacity, the design efficiency ranges from approximately 78% to 80.4%, ensuring optimal energy utilization.
