Fire Tube Boiler  Hot Water Boiler 350kw-14000kw 

WNS series fire tube gas (oil) boiler

WNS fire tube boiler, WNS means horizontal type furnace combustion boiler with gas/oil burner. Its fire-tube boilers and flue gas three pass boiler, special wet back structure make sure long using lifespan.

 Advantages  WNS boiler features 

1. 100% Safety Control Boiler & Strict Boiler Quality Control

1)All welding strictly meet the requirements of China NB/T 47014(JB/T 4708)

2)Anti Dry Heating Control System with double safety valves, double water level gauges, double secure of safe operation

3)With explosion-proof door with fire viewer, If burner failure ignition, this door can release the pressure out, protect the damage to welding parts

2. Energy Saving & High Efficiency

1)Spiral fire tube, the advanced technology, to enhance the boiler thermal power 10-15% higher than normal, and avoid the spiral tube from ash deposition and wearing

2)Spirally corrugated furnace & Wet back structure, increased 10% heating area, avoid damaged by heat expansion, reduce the back tube sheet temperature and protect it from cracking

3. High Quality Steam-Wetness Below 1%

1) We equip a steam separation under the steam output port.

2)With continuous water feed function,Make the water level is stable instead of  big differences

3)Bigger water tank design, boiler with bigger water volume and bigger steam space

Remark  Boiler Auxiliaries 

1. Burner: We use stable brand burner, we have closed cooperation with Baltur, Riello, Unigas, Oilon etc.

2. Economizer: Recycle exhausted smoke to heat feed water, increase 40 ℃ to the feed water before boiler, reduce exhausted smoke temperature below 95 ℃, save fuel at least 6% per hour

3. Control panel: PLC program system + 10” Touch Screen | Voice function | Designed with converter to save electricity | With protection devices for overheating, overpressure, lacking water, gas leak detection, flameout etc.
