WNS series gas/oil fired industrial steam boiler use international most mature three-pass all wet back structure,safety and reliable .Use waveform furnace ,strengthens the disturbance of the smoke and increases the radiation heat transfer area ;increases the stiffness of the furnace and effectively reduces the thermal stress of the furnace;enhance heat transfer and promote the combustion of fuel in the furnace.The heating surface is arranged symmetrically with solid structural strength and reasonable water circulation .Boiler up part inside has full water capacity ,big steam space and good quality steam .During procession ,the water level fluctuation is small .Big distance between two ends boiler ,big diameter of tubes ,all of these ensure good natural circulation . Steam boiler with very small heat loss  because of unique furnace and flue gas thermal surface design .

Boiler Feature
1. Safe precipitation time is sufficient
The combustion chamber of the boiler is arranged and the water level is determined in accordance with the national regulations. At the same time, it is strictly in accordance with the time requirements of the water level fluctuation standard of the international general norms. It has sufficient safe precipitation space to ensure the operation safety of the boiler.
2. Boiler maintenance is convenient
The top of the boiler is provided with manhole, and the front and rear of the boiler is provided with hand hole device, which is convenient for inspecting and cleaning the device inside the boiler and the bottom of the boiler.
3. Unique seal of front and rear smoke box
Smoke box with double open door, easy to open, multi-level labyrinth seal, special sealing material, good compression performance, completely prevent smoke leakage, can be used again.
4. Reliable protection of pressure and water level
Multiple control protection for boiler pressure and water level, as well as ultra-smoky temperature protection ensure the safety of boiler operation.
5. Advanced level of automatic control
The boiler controller is made of Siemens and Delixi electric components with reliable performance.Chinese and English menu with LCD display, touch screen with remote control.

This steam boiler is widely used in different industries such as chemical plant, energy field, food factory, hospital, hotel, laundry, package plant, paper-making mill, pharmaceutical factory, slaughter house, tobacco factory, textiles plant, etc.
