WNS series oil/gas fired boiler adopts horizontal three-pass wet-back structure,large corrugated furnace and patented thread pipe technology,equipped with international first-level brand burners and valve groups,and independently developed high-matching PLC control system to realize muitiple linkages.The lock protection function protects the equipment running safely.

Performance advantage

1. Boiler design

Horizontal internal combustion three return journey full wet back design, 100% corrugated furnace, with good thermal retrability, water cooled retrorse chamber, retrorse chamber and back tubeplate butt joint, lowest stress, more reliable quality.

2, large diameter corrugated furnace

The boiler combustion chamber is composed of a large diameter full ripple furnace with large combustion space, complete fuel combustion, effective heat absorption and thermal expansion, and large radiation heating surface.

3. Sufficient heat

The heating area of the boiler is designed to be more than 25 square meters/ton, fully absorbing effective heat, low smoke exhaust temperature, small heat loss, ensuring sufficient output and high efficiency.

4. Steam quality

Pot shell diameter, large water capacity, strong adaptability to load changes, stable output, steam space volume, soda interface and steam outlet net distance is high, low steam humidity.

5. Multi-functional safety and explosion protection device

The back plate of the boiler is equipped with the explosion-proof device which is connected with the furnace to prevent the high energy of the discharge moment when the fuel is violently deflated in the furnace, and it can automatically reset. Meanwhile, it has the function of the fire-viewing mirror and the maintenance channel. It makes use of the adjustment of the burning flame in operation, and makes the furnace inspection and maintenance convenient.

6. 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.

7. 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.

8. 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.

9. 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.

10. 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.
