High Thermal Efficiency Horizontal Boiler Economizer with 1 Year Warranty and Serpentine Tube Design

Boiler economizers are heat exchange devices with finned tubes that heat liquids (typically water) to temperatures below their 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, it offers:

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

H-finned tubes can be manufactured as double H-finned tubes for enhanced rigidity, making them suitable for long tube rows.

The spiral finned economizer features a new design with spiral fin tubes that address serious 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 boiler quality
• Hydraulic test report to verify standard working pressure and safety
