WNS Series Hot Water Boiler Introduction

According to the structure can be divided into vertical hot water boiler and horizontal hot water boiler; According to the use can be divided into heating hot water boiler and bath hot water boiler; According to the structure can be divided into atmospheric pressure hot water boiler and pressurized hot water boiler; According to the fuel can be divided into natural gas hot water boiler, city gas hot water boiler, biogas hot water boiler, liquefied gas hot water boiler and so on. The WNS series hot water boiler is featured by environmental protection, energy saving, safety and automatic operation. It is very convenient to use. In addition, due to its economic operation, WNS series hot water boiler is more and more favored by everyone.

WNS Series Hot Water Boiler Advantages

Digitized manufacture

  1. The key processes including material cutting, rolling, drilling are made by advanced CNC machining process to reduce the assembly stress and extend boiler working lifetime.
  2. The front and back smoke chamber plates are cut by CNC plasma cutting machine with tidy and beautiful look.

 

Easy operation and maintenance

  1. Fully intelligent operation, with automatic adjustment and protection of burning, water level, temperature and steam pressure.
  2. The smoke box door uses the hinge structure for easy inspection, inventory and cleaning.

 

Longer working life

  1. The way to weld Smoke tube and tube sheet is to first expand to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boiler service life.
  2. Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint are test by radiographic inspection.
  3. Fin tube uses ND steel or stainless-steel material to avoid corrosion in the low temperature .
  4. Inspection stops are set up to guarantee the sequence of expanding and welding to avoid cracking of the tube sheet holes.

 

Less fuel consumption

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