Structural features and performance advantages

• The SZS series boiler adopts a double drum (or triple drum) D-type membrane fireplace chamber structure. The boiler consists of an upper (middle) and lower drum, membrane water-cooled wall, convective heat exchange tube bundle, superheater, tail energy-saving device, condenser, etc.
• The combustion chamber adopts a full membrane water-cooled wall structure, with good sealing, no air leakage, low heat dissipation, increased boiler heating surface, and improved thermal efficiency.
• Full membrane wall structure, good furnace and flue steel properties, strong blast resistance, and safe operation.
• Convection tube bundle single stroke, reducing smoke side resistance, optimal economic flow rate design, micro positive pressure combustion, improving heat transfer efficiency.
• It has larger furnace volume, cross-sectional width, and length dimensions, suitable for various burner arrangements. Facilitating the arrangement of multiple burners. Fuel stays in the furnace for a long time, burns more thoroughly, and has higher efficiency.
• The large furnace size meets the requirements of ultra-low nitrogen combustion, and when combined with the burner, NOx emissions can meet the environmental protection requirements of the usage site.
• There are multiple arrangements of water-cooled walls and convective heat exchange surfaces in the furnace, resulting in fast boiler heating, large boiler water capacity, and safe and stable operation.
• The boiler uses high-quality insulation materials and special construction techniques, resulting in minimal heat loss and fuel savings.
• Adopting a fully automatic burner with ignition program control and automatic control system for overpressure, shutdown, and gas leakage protection.
• The boiler adopts advanced electromechanical integrated fully automatic control technology. Remote human-computer interaction and data sharing can be realized through mobile Internet.
