High-Pressure Steam Boiler – FangKuai Boiler

High-pressure steam boilers, as defined by ASME Boiler & Pressure Vessel Code (BPVC) Section I, are those designed to operate at gauge pressures above 15 psig (≈ 1.03 bar). However, In industrial settings, “high-pressure” typically refers to boilers running between 100 psig (≈ 6.9 bar) and 800 psig (≈ 55.2 bar), with specialized units exceeding even higher pressures. FangKuai Boiler has extensive experience producing high-pressure steam boilers across this range, delivering reliable, efficient solutions for diverse industries.

1–10 t/h: Euromonitor 6 Condensing Steam Boiler

The Euromonitor 6 boiler is engineered for steam outputs 1 t/h – 10 t/h. Key features include:

• Fully Premixed Burner & Finned-Tube Heat Exchanger
  Achieves a thermal efficiency of up to 103.44 % (LHV basis) and maintains NOₓ emissions below 30 mg/Nm³ through optimized combustion chamber design.

• Compact Footprint
  Requires 40–50 % less floor space compared to conventional boilers of similar capacity, thanks to its integrated condensing heat recovery unit.

• Advanced PLC Control
  Industrial-grade, IEC 61131-3–compliant interface for real-time monitoring and parameter management.

Operating Pressure: 181 psig (≈ 12.5 bar)
Fuel Options: Natural gas, LPG, diesel, heavy oil, city gas

1–30 t/h: WNS Integrated Condensing Steam Boiler

For mid-range requirements (1–30 t/h), FangKuai offers the WNS series with fully integrated condenser, economizer, and boiler body. Highlights include:

• Uitraten Wing Condensation Technology
  Silicon-aluminum alloy finned tubes increase heat-exchange area by 20 %, reduce exhaust temperature by 20–30 °C, and cut footprint by 30 %.

• No-FGR-Condensate Design
  Optimized flue gas recirculation layout eliminates condensate formation in the FGR loop, preventing burner flame-outs.

• Enhanced Automation
  Fault detection, scale monitoring, and customizable control logic ensure safe, hands-off operation.

Rated Thermal Efficiency: up to 104 % (LHV)
Operating Pressure Options:

• 145 psig (≈ 10 bar)

• 181 psig (≈ 12.5 bar)

• 362psig (≈ 25 bar)

Fuel Flexibility: Natural gas, LPG, diesel, heavy oil

30–100 t/h: NSZS Series Water-Tube Steam Boiler

For larger capacities, the NSZS series delivers 10–150 t/h steam with superheated outputs up to 250 °C. Key specifications:

• High Thermal Efficiency
  ≥ 99 % (LHV basis per ISO 5738) achieved via SA-213T12 alloy water tubes, yielding heat-flux densities of 18.7 kW/m²·K.

• Space-Saving Design
  Double-drum vertical layout reduces install footprint by 40 % versus traditional horizontal boilers.

• Advanced Emissions Control
  Hybrid FGR + SCR system maintains NOₓ below 30 mg/m³ in petrochemical applications.

Operating Pressure: ≤800 psig (≈ 55.2 bar)
Fuel Compatibility: Natural gas, coke-oven gas, biogas, heavy oil, crude oil, etc.

Modular High-Pressure Boiler Systems

FangKuai’s modular solutions simplify installation and scalability:

• 40 t/h Packaged Superheated Module
  Pre-assembled skid with integrated economizer and safety systems, rated for 181 psig (≈ 12.5 bar).

• 60 t/h Split-Type Superheated Module
  Convection sections pre-fabricated for 40 % faster on-site installation, rated for 181 psig (≈ 12.5 bar).

Both modules feature Siemens PLC controls, triple-redundant safety interlocks, and are ASME Section I–certified.

Note: Pressure and temperature can be customized according to the process.
