The WNS Full Condensing High-efficiency Steam Boiler is an energy-saving equipment adopting advanced condensing technology to recover waste heat from flue gas. It features a lower flue gas temperature with a thermal efficiency of over 100%, saving approximately 10%-15% energy compared with traditional boilers.
The boiler adopts a wet-back central low-position symmetrical layout and a corrugated furnace tank, with a full flanged design for the combustion chamber and threaded smoke tubes. It achieves first-class energy efficiency and two-stage condensation, which reduces exhaust gas temperature and improves overall boiler efficiency.It uses clean fuels such as natural gas and diesel, and can greatly cut long-term operating costs. It is widely applicable to high-end food and beverage, pharmaceutical and chemical, textile printing and dyeing, papermaking & packaging, wood building materials, rubber & plastic, leather, grain and oil feed and other industries.
1、Wet-back design with central low symmetric layout and corrugated furnace tube.
2、Fully flanged combustion chamber design and threaded smoke tubes.
3、Condensing recovery of flue gas waste heat, low nitrogen emission and energy saving
4、Primary energy saving plus two-stage condensation structure reduces exhaust gas temperature and improves boiler efficiency
5、Easy maintenance
Equipped with fully open hinged double-layer sealed smoke box doors. A sight port and inspection door are arranged at the boiler rear, while manholes and handholes are installed on the furnace body to ensure no blind spots for flue gas and steam-water system maintenance.
6、Reliable accessories
Fitted with world-famous brand burners and an advanced and stable control system (all key components are imported brands). Valves and pumps adopt high-quality domestic and international brands to guarantee safe and stable boiler operation.
7、Standardized manufacturing
Design and production are carried out in strict accordance with national and industrial standards throughout the whole manufacturing process. Advanced production processes ensure excellent overall boiler quality.
8、Advanced automatic control system
The boiler supports fully automatic operation with strong expandability of the control system
It is highly suitable for environments with high working pressure, with outstanding heat absorption rate and thermal efficiency.
