20 tons steam boiler perfect solution

1. 4×5-Ton WNS Condensing Steam Boilers (Modular Cascade)

Product Highlights

• Full Premix Combustion: Ensures stable flame and complete fuel burn, reducing unburned hydrocarbons.

• Feather-Tube Heat Exchanger: Up to 5× the heating surface area, boosting overall efficiency.

• Deep Condensation: Flue-gas temperature as low as 20 °C to reclaim latent heat.

Performance & Economy

• Thermal Efficiency ≥ 105 %: Extra heat recovery translates into over 10 % fuel savings.

• Modular Control: Intelligent PLC system stages boilers on/off based on actual load—minimizing cycling losses.

Environmental & Safety

• Ultra-Low NOₓ (<30 mg/Nm³): Meets even the strictest regional emission standards.

• Multi-Layer Protections: Includes over-pressure, over-temperature, scale-build-up and controller-fault alarms.

Ideal Applications

Best for facilities with variable loads—such as laundries, food-processing lines or light-industry workshops—where turning units on and off helps optimize efficiency.

Recommendation

Great balance of upfront cost, flexibility and long-term fuel savings. ★★★★☆ (4.7/5)

2. Dual 10-Ton Ourui7 Steam Boilers (Redundant Standby)

Product Highlights

• High-Efficiency Premix Burners: Compact footprint while maintaining complete combustion.

• Integrated Condensing Heat Recovery: Single-skid design with built-in economizer and condenser.

Performance & Economy

• Quick Start/Stop: Each boiler can ramp from idle to full load in under 5 minutes.

• Standby Redundancy: One unit can back up the other, ensuring zero downtime during maintenance.

Environmental & Safety

• Low NOₓ Emissions (<30 mg/Nm³) with adjustable flue-gas recirculation for peak load and low-load conditions.

• Automated Diagnostics: Cloud-based monitoring for “discover → diagnose → detect → rectify → run” closed-loop service.

Ideal Applications

Pharmaceutical plants, hospitals and any 24/7 operation where reliability is non-negotiable and steam continuity must be guaranteed.

Recommendation

Best choice for critical processes requiring uninterrupted steam supply. ★★★★★ (4.9/5)

3. Single 10-Ton SZS Water-Tube Boiler (Line Expansion)

Product Highlights

• Vertical Drum & Membrane Wall Construction: High pressure tolerance and fast steam–water separation.

• Fuel Flexibility: Compatible with natural gas, LPG, city gas, diesel or heavy oil.

Performance & Economy

• Evaporation Capacity 10 – 50 t/h Per Unit: Easily stages additional modules as demand grows.

• High Turn-Down Ratio: 3:1 modulation ensures efficient part-load operation.

Environmental & Safety

• NOₓ ≤ 30 mg/Nm³: Achieved via full-premix burners and flue-gas recirculation.

• Scale-Build-Up Alarm: Protects tubes and maintains long-term performance.

Ideal Applications

Manufacturing lines ramping up capacity over time—food & beverage, paper mills or chemical plants looking to phase in extra steam.

Recommendation

If your factory needs to expand. You can add an SZS water tube steam boiler based on the original boiler. ★★★★☆ (4.7/5)
