This WNS series boiler is extra low nitrogen emission, it is equipped with advanced oil gas burner, has high combustion efficiency and low nitrogen emission. moreover, it takes advantages of high efficiency condenser and economizer, to absorb the sensible heat in the high temperature flue gas that discharged from the boiler and the latent heat released from the vapour condensation, to improve the boiler thermal efficiency, which can reach as high as 105%.  

The boiler is fast assembly fire tube boiler with three pass structure, it has compact structure, small volume, strong load adaptability and low water quality requirement. This boiler adopts wet wet back structure, it can adapt to the high temperature, has a good sealing, increase the radiation heat transfer area and improve the heat transfer efficiency.
