150 PSI Industrial Low Pressure Gas And Oil-Fired Steam Boilers Manufacturers In China​

WNS series gas-fired (oil-fired) steam boiler

WNS type automatic horizontal steam boiler is a horizontal quick - mounted internal - burning three - return - trip fire tube boiler.The bifurcated flue gas is used to wash the second and third return flue gas pipes successively, and then the flue gas chamber is discharged into the atmosphere through the chimney.The boiler is fitted with movable front and rear smoke box covers to facilitate boiler maintenance.
Special Structure and High Efficiency: All system is well mounted on the base, its system is portable. The users no need to consider the pipeline installation, wire connection. After receiving the goods, just supply water, electricity, fuel. It is equipped with renowned brand burners(BALTUR, RIELLO, HOFAMAT, ECOFLAM), also finned tube type economizer can ensure boiler's thermal efficiency up to 95%.
High Quality Control: In manufacturing processes, we has adopting steel strength test, automatic steel cutting plate rolling/
welding,100% x-ray welding check, magnetic particle check c-scan ultrasonography Ultrasound check, fluorescent pene-trating check, hydraulic (water) pressure test, boiler thermal efficiency test, etc, to make sure all finished products is qualified.
Automatic Safe Operation: WNS series package steam boiler is equipped automatic burner ignition, automatic water-level control, auto-matic pressure control, automatic interlock chain stop protection, free settable working pressure, free settable ON/OFF time, visible system's working states on screen.
Easy Maintenance: WNS series boiler uses full water back tube-sheets instead of traditional dry back tube-sheet, can avoid the dry-fire broken, reduce the range of steel cooling contraction and hotting expansion. Also, we adopting openable smoke-boxes, users can replace the broken fire-tubes conveniently.
Steam Boiler Specification

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.
SAFETY FEATURES
