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.

Steam Boiler applicable industry

hot spring bath, sauna room, printing and dyeing textile, factory office school, medical pharmacy, hotel catering, food processing, chemical plant, sock factory heat setting, clothing processing, industrial steam washing, heating drying farm.

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.

Executive Standard

1. Design, manufacture, assembly, experiment and acceptance of boilers in strict accordance with national and industrial standards, including but not limited to the following standards: GB/T16508 Boiler Shell Boiler, TSG G0001 Boiler Safety Design Supervision Code, GB50273 Boiler Installation Engineering Construction and Acceptance Code

2. The main steel used in the boiler is 20 GB/T3087, which ensures the safety and reliability of the boiler.

3. Welding materials shall be selected according to NB/T47018. Full penetration welding with argon protection shall be performed on the boiler tube.
