WNS series oil & gas fired steam boiler is horizontal style, fire tube steam boiler with oil, diesel oil, light oil, heavy oil, natural gas, city gas, LPG gas as combustion fuel. WNS oil gas fired steam boiler uses internationally mature three-return structure, which is safe and reliable.

There are many advantages for adopting inner hull with wave shape, which speeds up the stirring of the smokes and increases the heat transfer area, increases the stiffness of furnace and effectively weakens thermal stress, enhances the heat transfer and promotes combustion in the furnace. The heated surface is laid out symmetrically, the structure is reliable, and water circulation system is reasonable. Unique combustion chamber design and scour way of smoke to heated area make the less heat loss.


  • Heating: Provide heating source for radiators, central air-conditioning, floor heating, etc.
  • Industry Users: Heating oil pipe, hot air curtain for industrial plant.
  • Recreation: together with water-water exchanger, provide hot water for swimming pool, saunas, beatuty salons.
  • Aquaculture: winter seafood, fish, shrimp etc


  • Gas fired Pressurized Hot Water Boiler construction is tried and tested three-pass and wet-back structure, more safe and reliable
  • Big combustion room design: increase furnace radiant heating area, decrease the boiler size, educe the emission of the Nox
  • Corrugated hearth make the boiler safe
  • Threaded tube: strengthen the heat transfer, increase the boiler heat efficiency
  • Multi-level sealing for flue gas chamber: no flue gas leakage
  • Boiler controller system can run for a long time under high temperature and high humidity condition
  • Multi-level protections like boiler pressure, hot water temperature, gas pressure protection and so on
  • High efficient thermal insulation material, low boiler surface temperature, the heat loss can be neglected
  • Produce according to the national standard, all pressurized components apply fine quality steel
  • Every boiler must be subject to strict inspection and testing before delivery, including hydraulic text and x-ray inspection
  • Selecting the most suitable burner to match the boiler so as to guarantee safety and reach rated output.
  • All components, such as pumps, valves are limited to choose international or national renowed-brands.
  • Introducing manhole and handhole: maintenance is convenient
  • Customer-tailored design is available
  • An Economizer (Devotion Brand) is optional and possible to save 15% fuel , decrease noise 20Db.
