1.Who am I ?

WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.

2. Main structure is the below:

3. What uniqure features do I have ?

Fire Tube Automatic5ton Gas Fired Wns Steam Boiler



3.1 Long working life

3-pass and wet-back are designed to avoid the damage of back tube sheet from the high temperature smoke.

3.2 Compact desegn
Threaded firetube and corrugated furnace are used to increase the heating area. That allows over 30% of the energy to be absorbed in the furnace. This means a shorter boiler overall. Definitely, it can save your boiler room construction costs.

3.3 Ease of maintenance and control
Everything is up front,adjustable and accessible.

3.4 New type economizer
It is made by finned ND tubes. It is smaller but the heat exchanging area is bigger than normal. By calculation, It can save around 5% fuel.

3.5 Low emissions
Lowering emissions in the ZOZEN-WNS series of boiler involves two key factors: (1) advanced burner solution; (2) the proper sizing of furnace to minimize nitrogen oxides and other contaminants from forming during the combustion process.

3.6 Safety control system


Fire Tube Automatic5ton Gas Fired Wns Steam Boiler
We design the safety interlock system with multiple protection and alarm functions

- Protection program of automatic ignition
- Locking and protection program of operation
- Protection program of extinction
- Protection program of completion
- Protection program of water pumps (pressure loss)
- Protection program of ignition failure
- Protection program of combustion engine malfunction
- Protection program of combustion engine flameout
- Sound-light alarm of high pressure
- Sound-light alarm of high limit water level
- Sound-light alarm of low limit water level
- Sound-light alarm of super-high temperature of hot water

8.Technical advantages

Fire Tube Automatic5ton Gas Fired Wns Steam Boiler


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 45ºC 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.
