About this product
Product information from the supplier.
Our Horizontal Coal-Fired Hot Water Boilers are engineered for high-performance industrial heating, utilizing an advanced three-way water-fired tube structure. The longitudinal arrangement of the single boiler, combined with dense water-cooled wall tubes on both sides of the furnace chamber, ensures a compact yet powerful design that maximizes heat absorption and structural integrity.
Designed for maximum economic efficiency, these boilers feature an expanded heating area and an optimized flue gas flow path. This strategic engineering significantly reduces exhaust temperatures and boosts overall thermal efficiency, resulting in lower operational costs and a sustainable energy solution for diverse industrial applications.

Frequently Asked Questions
Q: What is the primary benefit of the three-way water-fired tube structure?
It provides a more compact design and significantly increases the heat exchange surface area, which directly improves the boiler's overall thermal efficiency.
Q: How does this boiler reduce operational costs?
By utilizing a longer flue gas flow and dense water-cooled wall tubes, the boiler lowers the exhaust gas temperature, ensuring more heat is captured rather than wasted.
Q: What is the maximum thermal power available for the DZL series?
The series offers a wide range of capacities, reaching up to 63 MW for large-scale industrial heating requirements.
Q: What is the typical thermal efficiency range for these coal-fired boilers?
Depending on the model, the thermal efficiency ranges from 85.8% for the 0.7MW model up to 88.9% for the 63MW model.
Q: Can these boilers handle high working pressures?
Yes, the models are designed to operate safely at rated working pressures ranging from 0.7 MPa up to 1.25 MPa.
Q: What is the purpose of the water-cooled wall tubes?
They protect the furnace structure from extreme heat while simultaneously transferring that heat to the water, increasing the boiler's efficiency.
