Flue Gas Boiler Economizer Heat Exchanger with Max 120t/h Steam Production and 1 Year Warranty

Boiler economizers are heat exchange devices with finned tubes that heat liquids (typically water) to temperatures approaching but not exceeding the liquid's boiling point.

We manufacture three types of boiler economizers:

• Bare tube economizer
• H finned tube economizer
• Spiral finned tube economizer

The H-finned tube economizer is a high-efficiency heat exchanger consisting of H-finned tubes. Compared to bare tube economizers, H-finned tube models offer:

• Larger heat exchange area
• Reduced number of tubes required
• Increased flue gas flow area
• Reduced flue gas flow speed and abrasion

H-finned tubes can be manufactured as double H finned tubes for enhanced rigidity in long tube row applications. The spiral finned economizer features newly designed heat transfer equipment with spiral fin tubes to overcome abrasion issues and extend service life.

• Impact test and Strength calculation report with applied materials information
• 100%NDT(non-destructive inspection) report of steel plate, tube and electrode
• X-ray, γ-ray and liquid penetrant test inspection report (welding seam) to ensure the quality of the entire boiler
• Hydraulic test report to ensure standard working pressure and safety
