Frequently Asked Questions
It provides a more compact design and significantly increases the heat exchange surface area, which directly improves the boiler's overall thermal efficiency.
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.
The series offers a wide range of capacities, reaching up to 63 MW for large-scale industrial heating requirements.
Depending on the model, the thermal efficiency ranges from 85.8% for the 0.7MW model up to 88.9% for the 63MW model.
Yes, the models are designed to operate safely at rated working pressures ranging from 0.7 MPa up to 1.25 MPa.
They protect the furnace structure from extreme heat while simultaneously transferring that heat to the water, increasing the boiler's efficiency.
