Yuanda - Model WNS Series -Gas/Oil Boiler (fire tube boiler)

100% Safety Control Boiler & Strict Boiler Quality Control

1. All welding strictly meet the requirements of China NB/T 47014(JB/T 4708)
2. Anti Dry Heating Control System with double safety valves, double water level gauges, double secure of safe operation
3. With explosion-proof door with fire viewer, If burner failure ignition, this door can release the pressure out, protect the damage to welding parts

Energy Saving & High Efficiency

1. Spiral fire tube, the advanced technology, to enhance the boiler thermal power 10-15% higher than normal, and avoid the spiral tube from ash deposition and wearing
2. Spirally corrugated furnace & Wet back structure, increased 10% heating area, avoid damaged by heat expansion, reduce the back tube sheet temperature and protect it from cracking

High Quality Steam-Wetness Below 1%

1. We equip a steam separation under the steam output port.
2. With continuous water feed function,Make the water level is stable instead of  big differences
3. Bigger water tank design, boiler with bigger water volume and bigger steam space

1. Burner: We use stable brand burner, we have closed cooperation with Baltur, Riello, Unigas, Oilon etc.
2. Economizer: Recycle exhausted smoke to heat feed water, increase 40 ? to the feed water before boiler, reduce exhausted smoke temperature below 95 ?, save fuel at least 6% per hour
