This type of boiler has the characteristics of sufficient output, high thermal efficiency and small occupied area to help the enterprise save a lot of fuel costs and basic construction costs.

The WNS series steam boiler produced by ZOZEN Boiler can be fired by two different forms of fuel that are gas and oil, which can meet the special requirement of enterprise for boiler fuel adaptability. The WNS series steam boiler adopts a three-pass structure with the corrugated furnace and threaded smoke tubes to effectively strengthen the heat transfer and reduce the heat loss. In addition, ZOZEN WNS series steam boiler is equipped with the economizer and condenser at the end of flue gas duct to recycle the waste heat in the flue gas and improve the boiler thermal efficiency to over 98%. So far, this set of WNS series gas-fired and oil-fired three-pass condensing steam boiler has stably operated at Wuxi Guotai Color Printing Co., Ltd. for over 5 years, and has also provided a reliable guarantee for the production of flexible plastic packaging products.
