Flue Gas Boiler Economizer Heat Exchanger with Finned Tubes for Max. 120t/h Steam Production and 1 Year Warranty in Natural Circulation

Boiler economizers are high-efficiency heat exchange devices with finned tubes designed to heat liquids (typically water) without 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 particularly efficient design consisting of H-finned tubes. Compared to bare tube economizers, H-finned tube models offer several advantages:

• Increased heat exchange area
• Reduced number of required tubes
• Expanded flue gas flow area to decrease flow speed and abrasion
• Available in double H-finned tube configuration for enhanced rigidity in long tube rows

The spiral finned economizer represents our latest design innovation, featuring spiral fin tubes that effectively address 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 complete boiler quality
• Hydraulic test report to verify standard working pressure and safety
