Ship Spare Parts Exhaust Gas Economizer with Max. 20t/h Steam Production and 1 Year Warranty

Boiler economizers are heat exchange devices with finned tubes that 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 highly efficient heat exchanger consisting of H-finned tubes. Compared to bare tube economizers, H-finned tube versions 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 with high rigidity for long tube row applications. The spiral finned economizer is a newly designed heat transfer equipment that overcomes serious abrasion issues and extends service life.

The economizer functions to "economize" or save on cooling costs by allowing compressor shutdown while maintaining adequate cooling capacity, resulting in significant energy savings.

• 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
