6 Ton Capacity Gas Fuel Fire Tube Steam Boiler

Gas Fired Steam Boiler Introduction

Industrial WNS series oil fired boilers have reasonable price, guaranteed quality, direct supply from source sales mode, sufficient supply, high cost performance. WNS series steam boiler is designed with three-return thread smoke tube, large fuel combustion in furnace and high thermal efficiency. Fully automatic control operation ensures lower energy consumption of the boiler. In terms of safety, it is equipped with multiple interlock protection and aluminum silicate double layer insulation effect to reduce heat loss of the boiler.

Technical advantages

Digitized manufacture

• The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
• The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.

Easy operation and maintenance

• Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.

Longer working life

• Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
• Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
• Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
• Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.

Less fuel consumption

• High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
• Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
• Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.
