The SZS Water Tube Boiler by Devotion adopts a dual-drum, D-type arrangement with convection tube bundles on the left side and a furnace on the right. The furnace is surrounded by a membrane-type water-cooled wall, ensuring high safety and reducing the risk of tube explosions. The boiler operates fully automatically when equipped with a branded low-NOx burner and smart controls. It also features an external economizer and condenser, which effectively lower exhaust gas temperatures, significantly increasing boiler efficiency, and making it both energy-saving and efficient.

Key Features:

• Compact Structure & High Thermal Efficiency: The combustion chamber uses a full membrane-type water-cooled wall structure with excellent sealing, minimal heat dissipation, and a large heat transfer surface for high thermal efficiency.

• Fully Assembled for Easy Installation: The boiler is fully assembled at the factory, reducing on-site installation and commissioning time, and significantly shortening project timelines.

• Ultra-Low NOx Emissions: The boiler uses internationally renowned burners for more complete combustion, effectively reducing NOx emissions and achieving lower environmental impact.

• Intelligent Control System for Safety: The advanced PLC automatic control system provides automated protection functions such as ignition, shutdown, over-temperature, over-pressure, and gas leakage detection.

• IoT-Ready for Remote Monitoring: The boiler is compatible with IoT systems, allowing for remote human-machine interaction and data sharing, so users can monitor the boiler's operating status anytime, anywhere.

• Composite Circulation Circuit: The hot water boiler uses a composite circulation circuit, with forced circulation in the high-temperature zone and natural circulation in the low-temperature zone, ensuring safe and reliable water circulation.

• Natural Circulation Circuit: The steam boiler uses a natural circulation circuit, reducing water flow resistance and preventing stagnation and backflow, effectively minimizing the risk of tube explosions.

• Full Membrane Wall Structure to Prevent Tube Explosions: The membrane-type wall structure gives the furnace and flue high rigidity and strong resistance to an explosion, ensuring operational safety.

• High-Efficiency Convection Tube Bundle Design: The single-pass convection tube bundle reduces flue gas side resistance, ensuring efficient flow and heat transfer with micro-positive pressure combustion.

• Large Furnace Design for Low NOx Emissions: The large furnace size aids in achieving low NOx emissions while providing sufficient boiler output and high-quality steam.

Environmental and Efficiency Benefits:

• NOx Emissions: ≤30 mg/m³ with ultra-low NOx burners
• Thermal Efficiency: 101.5% with a condensing boiler design
