About this product
Product information from the supplier.
Our Horizontal Coal-Fired Hot Water Boilers are engineered for industrial-grade reliability, featuring an advanced three-way water-fired tube structure. By integrating a longitudinally arranged single boiler design with dense water-cooled wall tubes throughout the furnace chamber, this system maximizes heat absorption and structural stability for demanding thermal applications.
Designed for high-efficiency energy conversion, the boiler optimizes flue gas flow and expands the heating area to significantly reduce exhaust temperatures. This professional engineering approach ensures lower operational costs and superior thermal efficiency, providing a sustainable and economical heating solution for large-scale industrial facilities.

Frequently Asked Questions
Q: What are the primary benefits of a three-way water-fired tube structure?
This structure increases the heating surface area and improves the heat transfer coefficient, leading to higher thermal efficiency and better pressure resistance compared to traditional designs.
Q: How does the coal-fired hot water boiler reduce operational costs?
By optimizing the flue gas flow and utilizing water-cooled wall tubes, the boiler lowers the exhaust gas temperature, ensuring more heat is captured and less fuel is wasted.
Q: Can this boiler be used for varying industrial temperature requirements?
Yes, our models support a wide range of rated output water temperatures, from 95°C to 130°C, making them suitable for various heating and industrial processes.
Q: What is the maximum thermal power available for these boilers?
The series scales up to a rated thermal power of 63 MW, allowing it to serve everything from medium-sized facilities to large industrial plants.
Q: How does the water-cooled wall tube design prevent overheating?
The dense coverage of light tubes on both sides of the furnace chamber ensures constant water circulation, which absorbs heat rapidly and prevents the furnace walls from reaching critical temperatures.
Q: What is the typical thermal efficiency range for the DZL series?
Depending on the model, the thermal efficiency ranges from 85.8% for the 0.7MW unit up to 88.9% for the larger 56MW and 63MW units.
