>> Introduction
WNS condensing boiler is our patent technology, by using full wet back reverse chamber, the reverse chamber butt welded with the back tube head, more reliable. The combustion furnace by using the large diameter full corrugated furnace, large burning space to make the fuel burnt more efficiently. In order to improve the thermal efficiency, we equip economizer and condenser at the outlet of front smoke chamber.
Introduction
>> Features
Professional technology

1. Professional technology

Full wet back reverse chamber, butt welding for the reverse chamber and back dish head.

2. Large corrugated furnace

Boiler chamber by using large diameter corrugated furnace, large burning space to ensure fuel burnt more efficiently and large radiated heating area.
Professional technology
Sufficient output

3. Sufficient output

Calculated by per ton steam generated by ≥ 25㎡ heating surface.

4. Multi-function safety explosion-proof equipment

There is explosion-proof equipment at the back of the boiler, it will release the high pressure in case of the fuel deflagration, and it will reset automatically. It also can be used for fire-watching sightglass and maintenance.
