High Efficiency Boiler Economizer with Max 20t/h Steam Production and 5 Years Warranty for Industrial Use

High-quality ship spare parts exhaust gas economizer designed for optimal performance in marine boiler systems.

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 economizers 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 features newly designed heat transfer equipment with spiral fin tubes to overcome serious abrasion and extend service life.

The economizer's primary function is to "economize" or save on cooling costs by allowing the compressor to shut down while still maintaining adequate cooling, 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 ensure standard working pressure and safety
