WNS Integrated Condensing Steam Boiler
- New feather-wing tubes replace traditional smoke tubes, with high heat transfer efficiency, improved thermal efficiency, and reduced flue gas temperature.
- New corrugated furnace liners replace straight-segment corrugated composite furnace liners, improving heat transfer efficiency and better offsetting thermal stress.
- With new technical support, the boiler volume is reduced by 40%.
- The optimized FGR flue gas extraction port greatly shortens the length of FGR pipelines, saving space and improving the drawback of condensate water entering the fan.
- The economizer and condenser are integrated, featuring small volume and strong scale tolerance.
- All exposed parts are treated by shot blasting process and sprayed with high-temperature resistant paint, ensuring long service life.
- Large steam space with built-in steam-water separation device ensures steam dryness and quality.
- Reduced water volume enables fast steam response time.
- Shell-type full-wet back downstream double-return structure, micro-positive pressure combustion, low heat load, and low nitrogen oxide emissions.
- Both front smoke box and panel adopt double-layer sealing structure, and airtightness detection is carried out to ensure sealing.
- Detachable explosion-proof door ensures safe boiler operation and can be used as a furnace inspection hole.
- Adopts variable frequency continuous water supply system for stable operation.
- The boiler has a high degree of automatic control, high operation reliability, and simple and intuitive operation.
