Advantages WNS boiler features
1. 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
2. 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
3. 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

Optional Auxiliary Equipment
Boiler system can be configured with optional auxiliary equipment :
Economizer, Feed Water Pump, Water Softener, Deaerator, Steam/Water Separator, Condensate Return System, Fuel Storage & Supply System, Burner, Chimney, Boiler Control Cabinet, PLC Control System, Chemical Dosing System, Blowdown System, Water Treatment System

WNS Boiler Configuration Options
1. Component-by-Component Shipment
The boiler and its accessories are manufactured and shipped separately to the project site. Installation and commissioning are carried out on site by our engineers.
2. Skid-Mounted Configuration
For small-capacity boilers, most components and accessories are pre-installed and assembled at our factory before shipment.
For larger boilers, the system can be divided into several skid-mounted sections for easier transportation and faster on-site installation.
Factory Pre-Assembly → Easier Transportation → Faster On-Site Installation
