Your position: 
3500kg/hr Gas and Oil Boiler
WNS gas / oil fired steam boiler
-
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
-
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
-
WNS series steam boiler adopt fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
-
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45 degree to control heat lost.
-
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.
