Advantages and Features

• Double Drum, D-Type Structure: The SZS series boiler features a double drum, D-type structure with a full membrane wall design. The high-temperature flue gas is completely enclosed by the membrane wall, addressing the common issue of smoke leakage in conventional boilers due to incomplete sealing. This design ensures efficient and safe boiler operation, with reliable performance and high thermal efficiency. The boiler is equipped with an advanced intelligent control system, making operation easy and convenient.

• Explosion-Proof Safety: The boiler is equipped with spring-loaded safety explosion doors, strategically positioned to ensure ample pressure relief, meeting all safety requirements.

• Optimized Heat Transfer: The boiler design ensures a perfect match between the “boiler” and the “furnace,” considering factors such as flue gas velocity, steam/water circulation characteristics, flue gas flow patterns, flue gas impact on heating surfaces, and equipment flue gas pressure loss. This comprehensive approach optimizes the structure and material selection for the radiation, convection, and waste heat recovery heating surfaces, enhancing heat transfer efficiency and safety.

• Durable Exterior Panels: The boiler uses embedded folded plate external panels with a thickness of more than 3mm. These panels offer higher strength and durability compared to traditional color steel panels, are easy to remove, and provide a smooth, aesthetically pleasing exterior.

• High-Quality Insulation: The boiler is insulated with high thermal resistance lightweight materials, offering superior insulation compared to traditional refractory concrete or firebrick methods, while significantly reducing the overall weight of the boiler. The insulation layer includes unique radiation heat transfer insulation measures (heat emission film) to minimize radiation heat loss, often overlooked in traditional insulation processes.

• 100% Airtight: The full membrane wall structure ensures that the boiler operates with slight positive pressure on the flue gas side, fully sealed to prevent air leakage, eliminating the need for a draft fan.

• Easy Maintenance: Multiple inspection doors are provided, ensuring no blind spots during maintenance. Routine checks and repairs are easy and convenient.

• Safe Water Circulation: The inclination angle and height difference between the water-cooled wall and the water level plane are optimized to ensure absolute safety in water circulation while maximizing furnace volume.

• Perfect Matching of Boiler and Furnace: The furnace geometry is designed based on the flame size and temperature distribution of the burner, ensuring a perfect match between the flame and the furnace, optimizing heat transfer.

• Comprehensive Safety Measures: The boiler is equipped with multiple interlock protections for water level, pressure, flue gas temperature, furnace pressure, gas leakage, gas pressure anomalies, and auxiliary equipment operating status.

• Thermal Expansion Compensation: The drum and membrane wall feature unique designs and processes to effectively compensate for thermal expansion and contraction during boiler operation, enhancing the stability and lifespan of the boiler.
