WNS (LN) condensing boiler

WNS (LN) condensing boiler

Fuel type: natural gas
Typical application: garment factories, laundries, food manufacturers, power plants, district heating, schools, hospitals, heating and industrial steam and hot water supply etc.
Thermal efficiency: ≥100%
Boiler capacity: 1 – 10t/h

WNS (LN) is fitted with a corrugated furnace that is positioned in the lower part of the boiler. It adopts a two-pass flue gas condensing design and the amount of soot emitted complies with national emission requirements. The horizontal internal combustion two-pass wet-back structure consists of the corrugated furnace as the first pass, and smoke tubes with helical internal ribs as the second pass. The back tube plate of the boiler is not directly affected by the high-temperature flue gas, which leads to improved operating conditions and significant energy saving. The gas transported by the gas boiler pipelines serves as energy requiring no additional gas storage facility. The design improves on-site working conditions, significantly reducing labour intensity. It saves space and reduces operating and labour costs. In terms of maintenance, the combustion structures of hot water boilers and gas boilers are relatively simple, which means there are fewer components to maintain or repair. If the recovery rate of the condensing boiler is increased by 50%, the boiler efficiency can increase by approximately 5 to 6%, which makes it the best option for efficient use of resources. Not only heat is recovered, the consumption of water and chemicals are also reduced. At the same time, less harmful gases are emitted, thus, reducing environmental pollution as a result. This boiler has been gaining increasing popularity in many industries.
