WNS series gas boiler

Price: $3,500.00 - $48,000.00

WNS series gas boilers are energy-saving boilers with shell type, corrugated furnace and threaded smoke tubes. They adopt a three-pass wet-back structure. The fuel is burned in the furnace to produce high-temperature flue gas. It passes through the backfire chamber, the first convection tube bundle, The front smoke box, the second convection tube bundle, the rear smoke box, the normal pressure condenser, and the rear exhaust of the chimney.

Rated thermal power: 0.7 - 14MW
Rated thermal efficiency: ≥95%
Operating pressure: ≤1.25MPa
Available fuel: Natural gas, city gas, gas, coke oven gas, light diesel, etc.

Low Nitrogen Environmental Protection, High
Efficiency & Energy Saving

Safety

The full corrugated furnace structure avoids cracks caused by stress concentration and has a longer service life. The unique "return water distribution" and "spoiler partition" structural design allows the return water to reach the high temperature area first and ensures that the boiler water flows in the pot without stagnation or dead zones, ensuring safe, reliable and stable operation of the boiler.
More energy efficient

The energy saver adopts patented technology invented with independent intellectual property rights, taking into account heat transfer efficiency and operating resistance. Multi-stage "stepped" sealing has excellent heat insulation and sealing properties. The frameless outsourcing structure design and the overall coating of heat-resistant paint reduce heat dissipation loss.
High efficiency

Reconstruct the radiant heating surfaces of the furnace and backfire chamber to increase the radiant heat transfer. Increase the heating surface of the tail fin tube to strengthen and expand the heating surface. The smoke pipe adopts a special threaded pipe to reduce the flow resistance of smoke and enhance the heat transfer effect.
Low emissions

Brit typical low ammonia gas hot water boilers adopt a large combustion chamber design, which can make the fuel burn more fully and thoroughly when the furnace volume heat load is relatively low, and the nitrogen oxides are less than 30mg/Nm%.
