Product introduction:

WNS series oil / gas fired steam boiler belong to horizontal internal combustion three-return full wet back boiler, boiler radiation heating surface is whole corrugated furnace. Convection heating surface adopts screw smoke tube, big heating area, boiler sufficient steam output, thermal efficiency can reach more than 92%.

Boiler combustion chamber design is reasonable, fully adapted to city gas, natural gas, light diesel oil, heavy oil and other kinds of fuels.

Fuel combustion by micro-positive pressure in the furnace. Combustion completely, Exhaust gas pollution emission low. Boilers smoke blackness, soot blackness, concentration, noise and other technical index are all better than National Standard in same area.

The control system adopts mechatronics Mechanical-electrical integration control equipment and programmable logic controller(PLC) associated control mode, and supporting Italy Riello/Baltur, Finland Olin, Germany Weishaupt etc from International famous brand burner.

Performance Features:

1Three-return structure: adopts the international popular shell-type three-return ,full wet back structure, combustion chamber large volume design, to ensure the combustion more fully. Fuel combustion in the furnace by micro-positive pressure, high temperature smoke gas along the boiler furnace go backward through reverse flow combustor turn 180°into the first smoke flue tube bundle, pass the oppressive front smoke box then turn 180°into the second smoke flue tube bundle, after the convection heat transfer injection into the atmosphere.

2The corrugated furnace: the combustion chamber adopt full corrugated furnace structure, not only strengthen the flue gas disturbance, but also increased the radiation transfer area; not only increase the rigidity of the furnace, but also effectively weaken expansion stress of furnace; both enhance the heat transfer effect, and promote the fuel combustion in the furnace.

3The unique pipe and tube sheet welding technology: adopts the first pre-expansion and then all welding, and then expanded connection advanced technology. Both to prevent the pipe gap corrosion, and enhance the welding strength; adopts the high heat transfer coefficient of the screw smoke tube, to strength the convective heat transfer effect, reduce the exhaust gas temperature, improve the boiler thermal efficiency.

4Symmetrical activities hinge joint front, back smoke door: easy to open, convenient for repair, clean up.

5Wet back structure: the boiler use wet back structure, full pull side butt weld,reliable performance, low maintenance costs.

6Rear-view device: rear view device design, easy to observe the combustion situation.

7Security: design over-temperature, overpressure, water-shortage, leakage detecting, flameout and other protection functions, boiler operation safe and reliable.
