Steam Boiler Structure
WNS series  gas fired steam boiler adopts shell type corrugated furnace structure, two passes design with wet back smoke-transfer chamber, Spirally corrugated tube technology , air pre-heater at the front of boiler.The energy-saving condenser at the top achieves third pass smoke flow,so that fresh air can fully absorb the waste heat from the flue gas to lower the waste smoke temperature to 60 degree centigrade. It is split-type frequency conversion burner, and mature technology, safe and stable operation, high heat efficiency,and is packaged in stainless steel, which looks elegant.

1. Steam boiler
Horizontal internal combustion three return journey full wet back design, corrugated furnace, with good thermal retrability, water cooled retrorse chamber, retrorse chamber and back tube plate butted on the edge, low 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 position of the boiler combustion chamber is arranged, the water level is determined in accordance with the regulations, and the water level fluctuation time requirements strictly in accordance with the international general norms and standards, with 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 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
