Zozen boiler WNS series oil&gas steam boiler adopts horizontal three-pass wet-back structure,equipped with international first-level brand burners and valve groups,and independently developed high-matching PLC control system to realize muitiple linkages.
1.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%.
2.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 penetrating check, hydraulic (water) pressure test, boiler thermal efficiency test,etc, to make sure all finished products is qualified.
3.Automatic Safe Operation: WNS series boiler is equipped automatic burner ignition, automatic water-level control, automatic pressure control, automatic interlock chain stop protection, free settable working pressure, free settable ON/OFF time, visible system’s working states on screen.
4.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.
