SZS Series Oil/Gas-fired Water Tube Steam Boiler

​​SZS Water Tube Steam Boiler System: High-Efficiency Industrial Thermal Solution​​

1. Dual Assurance of Heat Transfer & Operational Safety​

​The SZS ​​Water Tube Steam Boiler​​ employs a scientifically optimized heating surface layout combined with a reinforced membrane wall structure, delivering stable steam output of 10-50t/h at 250°C (482°F) while supporting short-term 110% overload operations. Its dual-drum design minimizes water volume, enabling rapid pressure release within 15 minutes during power outages. The micro-positive pressure combustion environment (50-200Pa) prevents cold air infiltration, ensuring consistent efficiency for continuous processes such as chemical distillation and metallurgical heat treatment. Annual operational reliability reaches 98.6% as certified by ISO 19438 standards.

​​2. Combustion Innovation & Emission Compliance​​

Reverse-flow combustion technology in this ​​Water Tube Steam Boiler​​ achieves over 98% fuel efficiency with ≤2% unburned carbon residue. A three-stage flue gas treatment system reduces exhaust temperatures below 100°C (212°F) and cuts NOx emissions to 30mg/m³, meeting Class 1 regional environmental regulations. Integrated low-NOx burners maintain noise levels under 75dB at 1m distance, while a 200mm-thick composite insulation layer (aluminum silicate + glass wool) limits casing heat loss to 0.8%. These features collectively reduce annual fuel consumption by 12-15% in high-demand sectors like textile dyeing and pulp processing.

​​3. Condensing Technology for Energy Recovery​​

The ​​Water Tube Steam Boiler​​’s ND steel condensing module recovers both sensible and latent heat from flue gases, boosting thermal efficiency by 8-10% compared to conventional models. Laboratory tests confirm triple the corrosion resistance in acidic exhaust environments relative to standard carbon steel units. This durability extends equipment lifespan in 24/7 applications such as food sterilization (121°C/250°F batch processing) and mine dewatering systems, where energy waste reduction is critical.

4. Modular Engineering & Cost-Effective Maintenance​​

Pre-assembled modules in the ​​Water Tube Steam Boiler​​ slash installation time by 60%, with bolt-on aluminum cladding allowing full internal access within four hours. Maintenance logs from petrochemical plants document a 40% annual cost reduction compared to traditional fire-tube boilers. ASME-certified pressure sensors and explosion-proof doors enhance safety compliance, while smart diagnostics enable predictive maintenance—key advantages for industries requiring minimal downtime, such as pharmaceutical manufacturing and alloy production.

​​5. Cross-Industry Adaptability & Performance​​

Proven across diverse sectors, the SZS ​​Water Tube Steam Boiler​​ provides tailored steam solutions for chemical reactor heating, metal annealing furnaces, and packaged food sterilization lines. Its compact footprint and fuel flexibility (compatible with natural gas, biogas, or light oil) align with global sustainability goals, achieving emission levels 20% below most regional limits. With rapid load response capabilities and ≤30mg/m³ NOx output, this water tube steam boiler balances productivity and environmental responsibility for heavy industries worldwide.
