Product Description
WNS series oil or gas firde steam boiler is the horizontal,3-pass,fire-tube boiler.
Fuel can be light oil,heavy oil,natural gas,etc.
Dimention and other parameters could be customized.

The steam boiler form TECHTOP in an output range from 1t/h to 20t/h are avilable for a wide range or options.
Performances :
1, maximum energy efficiency,; 
2, Fully-automatic control and running
3, Three-pass and wet-back structure
4, Threaded tube: Strengthen the heat transfer, increase the boiler heat efficiency

1. Adopting tried and tested three-pass and wet-back structure, more safe and reliable
2. Big combustion room design: Increase furnace radiant heating area, decrease the boiler size, reduce the emission of the NOx
3. Corrugated hearth make the boiler more safe
4. Threaded tube: Strengthen the heat transfer, increase the boiler heat efficiency
5. Multi-level sealing for flue gas chamber: No flue gas leakage
6. Boiler controlling system can run for a long time under high temperature and high humidity condition
7. Multi-level protections like boiler pressure, hot water temperature, gas pressure protection and so on. 
8. High efficient thermal insulation material, low boiler surface temperature, the heat loss can be neglected
9. Produce according to the national standard, all pressurized components apply fine quality steel
10. Every boiler must be subject to strict inspection and testing before delivery, including hydraulic test and X-ray inspection
11. Selecting the most suitable burner to match the boiler so as to guarantee safety and reach rated output
12. All components, such as pumps, valves are limited to choose international or national renowned- brands. 
13. Introducing manhole and hand hole: Maintenance is convenient customer-tailored design is available. 
14. An economizer is optional and possible to save 15% fuel, decrease noise 20dB. 
Boiler controlling and safety systems
1. The controlling and safety systems are interlocked in an electric control cabinet (ECC).
2. The burning and security operation are controlled by ECC. It has the following basic functions:
Protection program of automatic ignition
Locking and protection program of operationProtection 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
Protection program of gas leakage
3. Alarm systemSound-light alarm of steam pressure and super-high steam pressure
Sound-light alarm of high and low limit water level
Sound-light alarm of pressure loss in water pumps.
