Being one-piece condensing steam boiler low nitrogen gas

 Gas steam boiler with high thermal efficiency

WNS condensing integrated gas steam boiler workshop

WNS series

Equipped with an ultra-low nitrogen burner, and adopts flue gas external circulation (FGR) to make the emission of nitrogen oxides below 30mg.

Our factory has launched an integrated low-nitrogen condensing steam boiler. The water temperature of the boiler water can reach 85 degrees after passing through the economizer and the condenser, and the rehearsal temperature of the exhaust gas is about 65 degrees, which significantly improves the thermal efficiency.

One, 2 tons of integrated condensing low nitrogen 30mg technical parameters

# #1.1 Rated evaporation: 2.0T/h    √

# #1.2 Type: Horizontal   √

# #1.3 Internal structure: three return trips,  √

1.4 Rated working pressure (Mpa): 1.0 Mpa 1.25Mpa 1.6Mpa 2.5Mpa
