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 .

Technical parameters

Feature 

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.

FAQ

1. What are the available fuel for the oil gas fired boiler?

Oil gas fired boiler could burn both liquid fuel and gaseous fuel. The liquid fuel could be heavy oil, light oil, diesel, furnace oil, bunker oil, LPG (liquefied petroleum gas), etc. The gaseous fuel could be natural gas, city gas, bio-gas, etc.

2. Whether the boiler can burn dual fuel or multi-fuel?

Industrail steam boilers  have oil burner, gas burner, and oil&gas dual fuel burner, we can offer the specific burner based on customers’ requirement.

3. What is the texture of spirally corrugated tube?

The texture of spirally corrugated tube is 20#.

4. The brand of burner?

The brands of burner are Italy Baltur, Rellio, Elco, etc.

5. What is the thickness of combustion chamber?

the thickness of corrugated furnace is different based on working pressure and furnace diameter, generally, the thickness is between 10~18mm, large combustion space, and combustion sufficient.

6. What is the advantages of fire tube boiler?

This fire tube steam boiler has compact structure and convenient operation, strong load adaptability, lower water quality requirement, and the failure rate of it is lower than 0.1!

7. Details of electric control cabinet.

Electric control cabinet adopts PLC touch screen, display in English. It shows working condition details of boiler, such as water temperature, water pressure, exhaust gas temperature, and over-pressure alarm, etc. In addition, the cabinet is used for set up the parameter, record and analyze the operation data, etc.

8. What is the inlet pressure of gas burner?

The inlet gas pressure is different for different capacity boiler, for example, the pressure for 2 ton steam capacity boiler is about 8~10KPa, while for 4 ton steam capacity boiler is about 18~20KPa.
