Ship Spare Parts Exhaust Gas Boiler Economizer with Max. 20t/h Steam Production, 1 Year Warranty, and More than 5 Years Warranty for Core Components
Boiler economizers are heat exchange devices with finned tubes that heat liquids (typically water) to temperatures below their boiling points. 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 models offer:
- Expanded heat exchange area
- Reduced number of required tubes
- 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 a new design with spiral fin tubes to overcome abrasion issues and extend service life.
The economizer functions to reduce cooling costs by allowing compressor shutdown while maintaining adequate cooling capacity, resulting in significant energy savings.
