SZS Water-Tube Hot Water Boiler

The Devotion SZS water-tube boiler adopts a double-drum longitudinal D-type layout, with the convection tube bundle on the left side and the furnace on the right side. The furnace is surrounded by a membrane water-cooled wall, ensuring high safety and reliability with a low risk of tube explosions. It has a renowned low-NOx burner, featuring micro-positive pressure combustion and intelligent control for fully automated boiler operation. External independent economizers and condensers effectively reduce exhaust gas temperature, significantly improving boiler efficiency, making it energy-saving and highly efficient.

Compact Structure and High Thermal Efficiency

The combustion chamber features a full membrane water-cooled wall structure with excellent sealing, minimal heat loss, large heating surface, and high thermal efficiency.

Fully Assembled for Easy Installation

The boiler is fully assembled and factory-tested, ready for operation after installation and commissioning, greatly reducing the project timeline.

Ultra-Low NOx Burner for Green Emissions

Equipped with internationally renowned brand burners, combustion is more complete, effectively reducing NOx generation and lowering emissions.

Intelligent Control Technology for Safety

Advanced PLC automatic control technology offers protection for ignition, flameout, over-temperature, overpressure, and gas leakage.

IoT-Compatible for Remote Control

The system supports remote human-machine interaction and data sharing through IoT, enabling you to monitor boiler operations anytime, anywhere.

Composite Circulation Loop

The hot water boiler uses a composite circulation loop, with forced circulation in high-temperature areas and natural circulation in low-temperature areas, ensuring safe and reliable water circulation.

Natural Circulation Loop

The steam boiler adopts a natural circulation loop with low flow resistance, preventing stagnation and backflow, effectively avoiding tube explosions.

Full Membrane Wall Structure for Explosion Resistance

The full membrane wall structure provides excellent rigidity in the furnace and flue, offering strong explosion resistance and safe operation.

Single-Pass Convection Tube Bundle for High Flow Efficiency

This design reduces flue gas resistance and features an optimal economic flow speed with micro-positive pressure combustion, enhancing heat transfer efficiency.

Large Furnace Design for Low-NOx Emissions

The large furnace size facilitates the achievement of low-NOx performance, ensuring sufficient steam output and higher quality heat output.
