3-Pass Wetback Fire Tube Industrial Steam Boiler

About this part

This 3-Pass Wetback Fire Tube Steam Boiler uses a water-cooled combustion reversal chamber to reduce rear refractory exposure. Actual efficiency, steam dryness, and response depend on the selected boiler, burner, feedwater quality, and operating conditions.

Key features

• Wetback reversal chamber design that reduces dependence on rear refractory maintenance
• Corrugated furnace flue tube maximizing heat transfer and absorbing thermal expansion
• Generous steam disengagement area delivering ultra-dry saturated steam (dryness fraction > 0.99)
• Full front and rear hinged access doors for effortless tube cleaning and annual inspection
• Modulating monoblock dual-fuel burner with automated flue gas oxygen trim integration

Typical applications and wear

Textile processing, RMG dyeing, edible oil refineries, pharmaceuticals, and breweries. Wear is caused by waterside scaling from poor water quality and front door rope seal degradation.

Compliance

Available for designs referencing ASME Section I, EN 12953, CE, and local boiler-inspector requirements; final compliance depends on the exact project and certification.
