Technical advantages

    Digitized manufacture

  • The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
  • The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
  • Easy operation and maintenance

  • Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
  • Longer working life

  • Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
  • Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
  • Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
  • Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
  • Less fuel consumption

  • High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
  • Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
  • Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.
