1. Inside the Industrial Boiler Production Hub
Industrial boiler production base
The core of any boiler maker lies in its manufacturing capabilities. Fangkuai’s workshops are a testament to industrial scale and precision engineering.
- Material Handling & Preparation: Sophisticated boiler manufacturing begins here. Plasma cutters, laser cutters, and flame cutting machines handle steel plate and tube cutting with extreme accuracy. Dedicated pre-treatment lines then ensure steel surfaces are cleaned, straightened, and primed to perfection before forming.
- Shaping & Forming: Heavy-duty equipment meets Class A boiler requirements. Plate rolls capable of bending 20-46 mm cold steel form boiler drums and furnace shells. Pipe bending machines shape complex waterwall and superheater elements. Additional bevelling machines, presses, and dies precisely prepare components for welding.
- Welding & Heat Treatment: Quality industrial boiler construction relies on advanced joining technology. Automated systems dominate: submerged arc welders handle long seams, dedicated TIG/MIG cells tackle precision parts, and robotic welders ensure consistent quality on complex assemblies like headers. Critical pre-heating and post-weld heat treatment (PWHT) in large furnaces guarantee material integrity and manage stresses per stringent codes.
- Assembly & Quality Assurance: Massive overhead cranes (10+ ton capacity) position major assemblies like drums onto robust alignment jigs. Then, rigorous inspection takes over. RT (radiographic testing), UT (ultrasonic testing), and stringent hydrostatic pressure tests rigorously verify every joint and pressure part. On-site spectrometers provide rapid material certification.
- Dedicated Production Lines: High-volume boiler manufacturing requires specialization. Fangkuai operates integrated lines for key components:
- Waterwall Panel Lines: Incorporating automated welding systems for consistent, high-quality membrane walls.
- Serpentine Tube Lines: Combining bending, precise TIG welding stations, and inline NDT for efficient superheater/economizer bundle fabrication.
- Header Fabrication Stations: Equipped for accurate drilling and automated welding of end caps.

2. Pioneering Industrial Boiler Research & Testing
Core Testing Capabilities
A full-condition laboratory validates boiler performance across dynamic operating scenarios. It replicates real-world conditions via multi-loop steam/water simulation systems featuring:
- Multi-fuel burners (gas/biomass/oil) with transient load control (≥5%/min ramp rates).
- Adaptive thermal circuits that mimic cold starts, load changes, and trip events, covering flows (0.5–200 m³/h) and pressures (≤32 MPa).
- High-accuracy instrumentation (300+ sensors, ±0.1% flowmeters, calibrated per ASME PTC 4).
Advanced Analysis & Certification
This lab specializes in failure prediction and performance optimization through:
- Transient diagnostics: High-speed data acquisition (≥100 Hz) detects combustion oscillations/hydrodynamic instabilities.
- Digital twin integration: Combines test data with CFD/FEA models for efficiency decay/NOx prediction.
- Environmental simulation: Climate chambers (-40°C to +50°C) and flue gas recyclers (O₂ control ±0.2%) test extreme conditions.
- Certification testing: TÜV/ASME-accredited for steam purity (Na⁺/SiO₂ monitoring) and burner compliance (EN 676).
