Frequently Asked Questions

Q: What is the primary advantage of the threaded flue pipe design?

The threaded flue pipes increase the heat exchange surface area, allowing the boiler to heat up faster and achieve a higher thermal efficiency of up to 89%.

Q: How does the boiler handle sudden power failures?

Thanks to the optimized water capacity, the boiler maintains enough thermal inertia to prevent accidents caused by the sudden vaporization of water during power outages.

Q: Can this boiler help in reducing industrial emissions?

Yes, the large furnace chamber and integrated rear dust separation room significantly lower the original dust concentration in the exhaust gas.

Q: What is the range of steam capacity available for these boilers?

We offer a wide range of capacities to suit different industrial scales, starting from 1 t/h (DZL1) up to 80 t/h (DZL80).

Q: Is the thermal efficiency of the boiler consistent over time?

Yes, our boilers are designed with high-durability materials and precision engineering to ensure the efficiency remains lifelong unchanged.

Q: What is the maximum working pressure supported by these models?

The rated working pressure for our coal-fired steam boiler series ranges from 0.7 MPa up to 1.6 MPa, depending on the specific model selected.
