Product Description

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.

It is full-automatic oil(gas) fired packaged steam boiler; adopting horizontal internal micro positive pressure combustion, full wetback design, high efficiency spirally corrugated tubes, fuel economizer and reasonable insulation package; the thermal efficiency can reach more than 90%. Its novel design, rational structural and nice performance achieved perfect quality and nice performance.

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.

Gas/oil fired steam boiler is widely used in hospitals, schools, textile mills, garment factories, large supermarket, garment factories, dyeing factory, hotel, dining room, restaurant, food factory, beverage factory, soy products, meat products factory, cannery, brewery, pharmaceutical factory, packaging plant, building materials factory, paint factory, swimming pool and other places of the enterprises and institutions.
